Gearing Up
Every year, the show organizers at Messe Stuttgart hold a press conference
to promote the world’s largest machine-vision exposition, VISION, which
will be held November 3–5, 2009. Leading off last month’s press conference, Thomas Walter, director of the industrial solutions division of Messe
Stuttgart, spoke of new incentives to attract visitors. These will include a
three-day series of talks featuring more than 40 speakers, tutorial workshops
to introduce engineers to machine-vision technology, a system integration area showing
machine-vision systems in action, and an area devoted to automotive applications.
Thinking about the future, VISION will now include a youth research competition that will
provide 17–20-year-old students an exhibition stand for their machine-vision projects. Moreover, innovative German startup companies will be provided 80% of the funds needed for an
exhibition booth by the German government. Topping this off, the show organizers expect
more than 6000 attendees to visit the 300 exhibitors—roughly the same as in 2008.
After Walter’s positive outlook, however, Dietmar Ley, chairman of the VDMA Machine
Vision Group, brought a dose of reality by predicting that if the current business trend continues, turnover in the German machine-vision industry will probably fall in 2009 by 30%, to
€854 million—the same level of 2003. The glimmer of hope in Ley’s presentation related to
new opportunities for machine vision in areas outside of industrial production, specifically
security, agriculture, biomedical fields, and traffic monitoring.
Winds of change
Some of the new applications covered in this issue as well as traditional applications of machine
vision in manufacturing bode well for the machine-vision industry as global markets begin to
recover from recession. For example, wind turbine power has been expanding at double-digit
rates and has been identified in a recent study by the Automated Imaging Association as a growth
opportunity for machine vision. In this issue, an article by contributing editor Charlie Masi
describes how a thermography-based automated inspection system is being used to find cracks
and delaminations in turbine blades and keep wind turbine power systems in operation.
Machine vision in traditional manufacturing continues to improve product quality as shown in
an article by contributing editor Winn Hardin on automotive glass inspection. Another by editor
Andy Wilson describes a robotic work cell for inspecting military protective eyewear. Finally, in this
month’s Product Focus, Wilson describes how many innovative smart-camera vendors are making
their products easier to use by leveraging embedded processors and on-board software.
Innovation remains the fundamental ingredient in successful machine-vision products and
trade shows. This year, it will be on full display in Stuttgart, provided by students of machine
vision, entrepreneurs, and well-established component vendors and system integrators.

Short takes on the
leading edge
Vision measures diesel engine injectors
In the automotive market, dimensional problems during production of diesel engine injectors may cause problems in engine performance
or fuel consumption. During production, injectors pass through several shaping operations
before reaching the burr removal station, which
is the last phase before packaging.
Traditionally, the injectors are manually
inspected by operators, which is not cost
effective and is subject to human error. Consequently, an industrial vision system was
developed by Vistek (Istanbul, Turkey; www.
___
vistekas.com) for Bosch
Sanayi ve Ticaret to
________________
automate dimensional measurements with
50-μm precision. The burr removal station
was the most suitable point to install the
vision system and execute dimensional controls. Since the dimensional control opera-
tions are performed concurrently with the burr removal
process, the system does not
require additional time in the
production cycle.
To achieve the desired precision of nine height and diameter measurements, the injectors
are divided into eight subsections. The system captures one
image for each section with a
high-resolution camera from
IDS (Obersulm, Germany; www.ids-imag
ing.de) and then performs image processing
____
separately. The camera is mounted on a vertically moving platform to image different sections of each injector. The vision software was
developed using the Halcon interactive devel-
opment environment (IDE) HDevelop from
MVTec Software (Munich, Germany; www.
___
mvtec.com). Total inspection time for each
_______
injector is 7–9 s. A ______________
more complete system
description is available on the Vision Systems
Design web site.

(Kelheim, Germany; www.pco.de), and has
applications in biomedical research, astronomy, and security and defense.
The researchers said that sCMOS
can be considered unique in its ability to concurrently deliver on several
key parameters. Performance highlights of the first sCMOS technology sensor include 5.5-Mpixel (2560
× 2160 pixels) format; read noise of
<2 e- rms @ 30 frames/s and <3 erms @ 100 frames/s; 100-frames/s
maximum rate; 6.5-mm pixel size;
dynamic range of >16,000:1 @ 30
frames/s; QEmax of 60%; and rolling or global shutter.

Vision system reads pesticide packages
To track the millions of bottles of pesticides
it produces per year, a global chemical manufacturer required a system to confirm the
traceability of its products after they were
packed into cases. After each bottle is filled
and sealed, an inkjet printer applies a Data
Matrix code on the top of each cap.
Once the open cases are packed, batches of
cases move along a conveyor for palletizing at 70
ft/min. To read the Data Matrix codes of these
bottles before palletizing, the company called
upon Matrix Systems and Solutions (Sanborn,
NY, USA; www.matrix-ssi.com) to develop an
automated machine-vision system.
Instead of using multiple cameras, a single,
monochrome 16-Mpixel GE4900 4872 ×
3248-pixel CCD camera from Prosilica (Burnaby, BC, Canada; www.prosilica.com) running at 3 frames/s was selected because of its
Gigabit Ethernet output, resolution capabilities, and speed. To capture a wide field of view,
a Planar T* 1.4/50 ZF 35-mm lens from Carl
Zeiss (Maple Grove, MN, USA; www.zeiss.
com) was mounted to the camera.
___
With a focal length of 51.7 mm, an aperture range of f/1.4–f/16, and a focusing range
of 0.45 m to infinity, the lens was selected
instead of a telecentric lens to reduce cost.
Since more than one type of product
needed to be inspected, the application required a relatively large field
of view with the dimensions of the
largest case being 397 × 320 mm and
the smallest being 271 × 205 mm.
In the initial system design,
Matrix tested Smart Vision Lights’

swivel mounts on the DFL allow the
lights to be adjusted, it was thought
that this would provide a good overhead lighting array. However, initial
testing of the DFL showed that the

technical pre-sales and support with JAI
(San Jose, CA, USA; www.jai.com) outlined two new proposals that will substantially increase the bandwidth of camerato-computer interfaces.
“Recent advances in high-speed
CMOS imagers,” says Kinney, “will
demand interfaces that are far faster
than the existing 6.25 Gbits/s currently
supported by the Camera Link standard.” To accomplish this, the committee is now studying two proposals.

failed to provide a useful image.
To overcome this problem, SVL customized its Large Light Panel (LLP) backlight
as a large diffuse ringlight, or tent light, by
cutting a hole in the center of the light for
camera placement (see Fig. 1). After the
LLP-2 was laser cut with a 30-mm hole in
the center, it was shipped and tested, virtually
eliminating the glare issues associated with
the DFL (see Fig. 2).
As the cases of product move into
the inspection station, a CMOS
GV-H450 laser sensor from Keyence
(Woodcliff Lake, NJ, USA; www.
___
keyence.com) triggers the lighting and camera system to capture
an image. After the image is captured, it is transferred via the camera’s Gigabit Ethernet interface to a
quad core processor with 8 Gbytes
of RAM running Linux.
Custom software is then used to
unskew the large image captured by
the lens, locate different quantities
and orientations of bottles, and to
read the Data Matrix code printed
on each cap. Where this data can
be read, cases are then moved along
the production line, sealed, picked
by a robot, and placed in cases.
If this data is unreadable, then

allows image data to be transferred
over 50 m of coaxial cable at a data rate
of 6.25 Gbits/s. For higher speeds, more
cables can be used in parallel. The proposed standard does not limit the number
of cables, so virtually unlimited bandwidth
can be made available.
“One of the benefits of this approach,” says
Kinney, “is that low-cost coaxial cables can
be used to transfer data from camera to computer. However, by designing camera interfaces using this approach, designers are tied
to one specific semiconductor vendor.” To
overcome this potential problem, Peter Helfet,
CEO of Eqcologic, has said that he is willing to
license other silicon vendors to ensure multiple sources for the devices.
The second high-speed link (HSLINK)
approach, proposed by DALSA (Waterloo, ON, Canada; www.dalsa.com) and
also being considered by the Camera Link
committee, is based on CX1 or CX4 cables.
HSLINK proposes that each twisted pair in
the cable runs at 3.125 Gbits/s, with options
for one pair (1x, so 3.125 Gbits/s total), four
pairs (4x, 12.5 Gbits/s), and 20 pairs (20x,
62.5 Gbits/s) using a 12x InfiniBand cable.
DALSA specifies a maximum cable
length of 15 m, although in the Camera

TR ADE SHOW RE VIE W
Lights, cameras, and action
highlight Robots & Vision Show
Despite the currently dire economic landscape, exhibitors at the June 2009 International Robots, Vision & Motion Control
Show (Rosemont, IL, USA) were pleasantly
surprised at the number and quality of the
attendees. In the space of three days, more
than 4000 visitors managed to visit some of
the 140 exhibitors on the floor and attend
tutorials and application sessions on robotics, machine vision, and motion control.
Reflecting the vibrancy of the industry, several companies used the show to
announce new products targeted firmly
toward developers of machine-vision systems. For example, as a first-time exhibitor at the show, Vieworks (Gyeonggi-do,
South Korea; www.vieworks.com) displayed a range of high-speed Camera Link
and GigE-based megapixel cameras.
Artur Didyk, engineering manager at
Components Express Inc. (CEI; Woodridge, IL, USA; www.componentsexpress.
com) showed how CEI’s ___________

allow non-PoE cameras to operate with a
Power over Ethernet switch. “Some sys_____________
tems require more than the 12.95 W supported by the current IEEE 802.3af (PoE)
standard,” says Didyk, “but by using the
new IEEE 802.3at (PoE+) standard, the BIT
MAXX adapter extends the power delivered
through Ethernet cables to 24 W, nearly
doubling the power that can be delivered
to a PoE system.”
“By using the BIT MAXX splitter, system
developers can eliminate lengthy power
cables, power supplies, and AC outlets they
may be using since the BIT MAXX splitter
FIGURE 1. System
developers can effectively eliminate any
lengthy power cables
they may be using
with GigE cameras since CEI’s BIT
MAXX splitter recovers both power and
data signals from the
attached PoE+ hub.
Using image sensors from Kodak and
Aptina, Vieworks currently offers 15 different cameras ranging from the VH-V264, a
640 × 480-pixel, 264-frame/s Camera Link
camera to the VC-4M160C-MC10, a 2352
× 1728-pixel, 160-frame/s Camera Link
camera based on an Aptina CMOS imager.
According to sales manager Peter Lee, the
company is currently looking for distribution in both the United States and Europe.
Like many GigE-based
cameras, the

recovers both power and data signals from
the attached PoE or PoE+ switch to deliver

Berst, president of CEI (see Fig. 1).
Reducing the number of components
needed to implement a vision system was also
the theme of Latab Elektronik (Vällingby,
Sweden; www.latab.se), another first-time
exhibitor at the show. Hendrik Schumann,
international sales manager, presented an

Eye Defense
Robots and linescan-based vision system team
for automated inspection of protective eyewear
Andrew Wilson, Editor
Protective eyewear destined for military use must withstand the effects
of different types of munitions and be free of defects such as scratches,
pits, or bubbles. The eyeglasses are molded from impact-resistant polycarbonate that is covered with a scratch-resistant coating. In addition to
inspecting these eyeglasses for defects within the polycarbonate itself,
any drips or runs caused by the application of the scratch-resistant coating must also be detected during the manufacturing process.
To ensure its product has no such defects, a US-based eyewear manufacturer called upon AV&R Vision & Robotics to develop an automated inspection system capable of analyzing surface defects.
“Usually,” says Michael Muldoon, business solutions engineer with
AV&R, “surface imperfections on the eyeglasses are inspected manually and compared to a ______________
scratch and dig paddle.” The paddle, available from Edmund Optics and other suppliers, is a means by which
any scratch or dig in the surface can be compared.
Using the paddle, any defect is defined by a scratch number followed
by the dig number. This _____
standard was developed during World War II
from Frankford
Arsenal in Philadelphia, PA, and is based on the appear__________
ance of a scratch. Because different scratch structures could have the
same appearance, it is difficult to determine the physical size of these
standards. But they are still in use for optical quality requirements. In
highly demanding optical quality, as in the defense industry, the biggest crack acceptable in the viewing area is a scratch-dig of 20-10, which
roughly corresponds to 2-μm width scratch and 1-μm diameter dig.
FIGURE 1. To perform
automatic surface inspection
of military eyewear, AV&R
has developed a roboticbased work cell that uses
robots and vision to inspect
eyeglass blanks at a rate
of approximately 15 parts
per minute.
Rack them up
After each individual lens blank is molded and coated, it is placed in a
rack that can contain between 6 and 24 pieces, depending on the type
of lens being manufactured. This rack is then manually placed inside

SynergX developed a brightfield inspection

with red LED line generators to inspect the surface of the glass. Initial results

they are aligned parallel to the glass edge. A laser line generator illuminates the edge of the window as it passes through the inspection station.
Each camera will inspect a portion of the edge for shiners, chips,
and other defects. The portion is determined by the AGI system based
on information collected by the squaring camera.
Since the edge detection creates a surface map based on how the
laser light deflects from the edge, the distance between laser light, glass
edge, and camera must be known. To stay within a set area, mirrors are
mounted on four vertical towers placed in each corner of the AGI inspection station. Based on the window’s edge location—as determined by the
squaring camera—the mirrors are moved up and down to maintain an
equal distance between laser, edge, and camera (see Fig. 2).

line that shines down on the glass as it passes below on the conveyor.
Below the conveyor, SyngerX mounted three more 2000-pixel Piranha2 Camera Link cameras to capture the transmitted light.
Each camera/LED pair can inspect an area up to 400 mm across,
hence the need for three cameras to capture the entire window as it
moves through the inspection zone. Above each camera is another
Fresnel lens that collects the light and focuses it onto the linear array.
Again, images are sent line-by-line to the compactPCI computer
and filtered for noise on the FPGA mezzanine board. Using pixelintensity information, the AGI system searches pixels for values that
fall within three ranges: acceptable, defective, and borderline.
When potentially defective values are located, the FPGA performs a
blob analysis and histogram of the blob to determine whether the defect is
large enough to be a defect and, if so, what type of defect. Based on the size,
type of defect, and location within the window, AGI makes a final determination whether the defect is acceptable, failed, or borderline (see Fig. 3).
The vision system stores defect statistics and images locally on a
hard drive and displays them on a separate operator’s PC located next
to the reject station. The display shows each window in the defect
accumulator in order, with defects highlighted in green for acceptable, yellow for borderline, and red for fail.

NEW High-End Performance Meets
Mainstream Pricing – The Basler aviator
The Basler aviator is a new
series of high-speed mainstream
cameras. Based on Kodak’s new
KAI-1050 CCD sensor with a
resolution of 1024 x 1024 pixels,
the first models of the aviator
series push the speed barrier to
a new height of 120 frames per
second. Progressive scan readout
and global shutter technology combined with a Camera Link
data interface make the aviator camera well suited for various application areas such as semiconductor and electronics
manufacturing, metrology, and medical imaging. Two additional models with two megapixel resolution will be available
in Q4/2009.
The Solution for Maximized Throughput –
The Basler sprint

developed high-speed line
scan camera family in the
Camera Link arena. Its sensor
was specifically developed
for Basler and is designed to
run at the highest possible
speed, to be very light sensitive, and to have an outstanding signal-to-noise ratio (SNR) under low light conditions.
The new Basler sprint line scan family includes models with
resolutions from 2k to 8k pixels and line rates from 20
kHz to 140 kHz. This means that the sprint is currently the
fastest line scan camera in its class.
Quick Integration and Easy Operation – The
Basler pylon Driver Package
The comprehensive Basler pylon driver package integrates
both a GigE Vision and an IEEE 1394 interface. The free
pylon software package provides drivers, a C++ camera
API, a viewer tool, comprehensive
documentation, and code samples
to make it easy to star t using and
integrating Basler cameras.

C.G. Masi, Contributing Editor
Finding flaws inside fiber-reinforced plastic
(FRP) wind-turbine blades is important to
organizations charged with keeping wind
turbines running and making electricity.
They can be owners of wind farms, windturbine producers and installers, or even
specialized crews providing turbine-blade
inspection as a service. To meet this need,

posite structures.
FRP is a composite material in which
highly inelastic fibers, oriented to resist
tensional loads, are “laid up” in layers held
together by a thermosetting plastic (such as
epoxy resin) matrix. Fibers in various layers
have different orientations to resist differently oriented stresses. For example, there
will be layers with fibers running directly
from a wind-turbine blade’s root to tip to
resist centrifugal forces. Other layers will
have fibers running diagonally to resist twisting forces. The plastic matrix carries compression and shear stresses between fibers,
forcing them to work together to achieve the
desired mechanical properties.
Delaminations arise when the plastic matrix fails under shear loads between

fiber layers. This may
be caused by the matrix
failing directly, or by
fibers failing and increasing the shear stress on
the matrix surrounding them, which causes
it to fail in turn. In any
case, the result is a flat
crack parallel to and at
some depth beneath the
blade’s surface.
These flaws form weak
spots that cause stress to concentrate in the
unbroken plastic at their margins, so they
tend to grow over time. Each time the load
peaks—for example, due to a wind gust—
the crack advances into previously unbroken
material, further weakening the blade. After
many load cycles, the blade weakens to the
point where it fails catastrophically.
AT’s customers use the company’s lock-in
thermal-wave inspection system to evaluate
the FRP skin’s condition on an ongoing basis
and as a failure-analysis tool.
The technique utilizes a phenomenon
called thermal waves, which can be set up
by depositing heat at the material surface in
a time-varying fashion. The thermal-wave
phenomenon exploits a similarity between
the general diffusion equation
ut = D uxx
[1]
and the wave equation
wtt = c2 wxx
[2]
where subscripts refer to partial differentiation. Thus ut is the first partial derivative of u
with respect to time, and wxx is the second partial derivative of w with respect to position. In
the diffusion equation, u represents the concentration of whatever is diffusing (such as
heat), so in Eqn. 1, it represents temperature.

In the wave equation, w represents whatever
is waving, such as water depth or sound pressure. Both D and c are scalar constants, and
both equations refer to plane waves.
Both equations have solutions when driven
by a sinusoidal forcing function
f = A sin(ωt)
[3]
Evanescent waves
If it were an ordinary wave, over time a standing wave would build up with constant amplitude through the material’s thickness. Being
an evanescent wave, however, by the time
it has reached one wavelength in, its amplitude is drastically reduced. Should the wave
encounter a crack or delamination, its penetration is even more drastically reduced
where A is a scalar amplitude, ω is the angular
frequency in radians per second, and t is time.
The difference is that the solution for Eqn. 1 is
an ordinary wave, which has a constant amplitude as it moves along, whereas the solution to
Eqn. 2 is an evanescent wave whose amplitude
decreases exponentially with distance from the
surface (see Fig. 1). While an ordinary wave
carries vibrations through the material, like a
sound wave through FRP, the oscillations in an
evanescent wave are trapped in a layer about a
wavelength thick below the material’s surface.
Thus, a sinusoidally varying source depositing heat on the surface of a turbine blade will
set up evanescent heat waves. When the heat
deposition is high, the surface temperature
rises rapidly and heat soaks into the material,
raising the temperature beneath. As the heat
source cools, however, the temperature at the
surface cools rapidly, pulling heat back out of
the interior and setting up a heat wave.

Lock-in detection relies on the fact that if you multiply two sinusoidal signals together, then integrate their product over an infinite time,
the resulting signal amplitude is a Dirac delta function (also called an
impulse function) of the difference in frequency between the two signals.
This technique, called convolution, makes it possible to pick out a particular signal in a noisy environment. The convolution integral equals the
product of the two signals multiplied by a delta function.
Scientists and engineers have used the convolution integral as the
basis for (among other things) Fourier transforms, resonant filters, heterodyne and superheterodyne radio receivers, and lock-in detectors.
Practical implementations generally combine an incoming signal (such
as a thermal-wave signal) and a locally synthesized comparison signal
at the frequency of interest. Lock-in detection’s ability to separate waves
at the forcing-function frequency from out-of-band noise makes it possible to improve lock-in thermography’s SNR.
In AT’s turbine-blade inspection application, the lock-in detector
is implemented in software. An infrared camera collects thousands of
images of the surface temperature pattern in an approximately 1-m2
area on the turbine blade during a test session. The frame rate is typically on the order of 1000X the forcing function frequency, so the
total number of images is roughly the number of forcing cycles in the
test times 1000. The amount of image-storage memory is thus another
practical constraint on how deeply engineers can look into a turbine
blade and how precisely they can pinpoint a defect’s depth.
The AT software, named IrNDT, multiplies the temperature of each
pixel in each image times the forcing function value at the instant the
image was taken, then adds the result to a memory location for that pixel.
After repeating the process for every image in the data set, the computer
holds a map of the convolution integral for each pixel in the image.
Random environmental influences do not correlate well with the
forcing function, so they have little influence on the map. Thermal
waves, however, correlate strongly with the forcing function and
thus strongly influence the map. Stronger thermal waves produce
larger integral values.
After subtracting a gray level and rescaling to fill the dynamic range,
the result is an image of the turbine blade with a more-or-less uniform
background level and darkened islands outlining cracks and delaminations. The closer a flaw is to the surface, the darker it appears. Grayscale levels can also be translated into false color maps coding depth
against a spectrum (see Fig. 2).

The technique starts with engineers specifying approximately seven
test areas at critical positions on the turbine blade. They predetermine
test parameters, such as modulation periods, frame rates, and acquisition durations, tailored to each particular area to be inspected. If these
sample areas show no defects, the blade passes. If any defects are found,
additional inspections covering more of the blade might be called for.
Damage severity depends on the size and location of defects found. For
example, a small delamination at the blade root, where both flexural

moments and tensile forces are highest, might be more serious than a
much larger void at the tip, where stresses are relatively small.
Wind turbine blades are made by encasing a relatively light core,
which determines the overall blade shape, in a sheath or skin made of
FRP, which carries the bulk of the stresses. This skin tends to be thicker
near the blade root, where forces and momentum are largest, and thinner farther along the blade. Thus, modulation periods and acquisition
times tend to be longest near the root. Frame rates, however, tend to be
controlled by the available image-acquisition memory. Generally, engineers want to acquire as many images as possible at each test location, so
they usually fill up the available memory for each test. So longer acquisition times call for lower frame rates.
The IrNDT software allows engineers to load the entire test procedure, including sample-area locations and the test parameters for
each area, into computer memory. Technicians can then mount the
test set, consisting of the computer, halogen lamp assembly, infrared
camera, and support electronics onto a movable platform attached
to the wind turbine (see Fig. 3). The platform provides 360° access

support mast allows them to reach the entire
blade length (see Fig. 4).
To set up the test, they aim the lamp assembly at an angle to the blade surface and aim the
camera normal to the blade. Thus, the camera
has a direct view of the blade with no projection effects and avoids specular reflections of
the lamp from the blade’s smooth surface. This
arrangement allows the camera to monitor surface temperatures across the test area while the
lamp assembly heats it more or less uniformly.
The slight variation in heat rate caused by bladesurface curvature is predictable and easily compensated by the IrNDT software.
The software controls the acquisition
through a proprietary interface called the
IRX-Box. It generates trigger signals for the
camera, and an illumination power-level
signal for the lamp-assembly power supply
(PowerBox). The camera returns acquired
images through a standard digital video interface such as GigE or FireWire.
Because wind-turbine installations vary so
much, AT builds what amounts to a semicustom system for each installation. They
have designed the IRX-Box, for example, to
accommodate most IR camera models and
specify the camera interface to match the
camera selected. The company so far has
more than 200 installations in the field.
“This method works very well for detecting defects near the surface,” Ferber points
out. “Users typically detect defects as deep as
10–15 mm below the surface. If you want to
see defects that are deeper into the material,
you have to do measurements over a longer
period of time. At some point, the measurement time becomes so long that it’s not worth
doing. For lock-in measurements, typical
measurement times would be between 30
sec to 5 min depending on what you want
to achieve. You can do measurements over a
half hour and you would see defects that are
deeper in, but imagine if you have to cover an
area of so many square meters! With 5 min
you could reach about 10 mm.”

The technique’s main advantage is that it
can cover large areas in one measurement and
routinely check condition of many blades rapidly. Also, the equipment is easily transportable
from one turbine to another. A third advantage
is that lock-in thermography is less affected by
external influences such as sun and wind, so
blades can be checked in situ, with no need to
dismount them and bring them into a shop.
Finally, software control allows engineers to
predefine a test procedure for a given blade type,
then have technicians use it for routine monitoring of many blades of that type. The engineers can then concentrate on failure analysis of
blades found to be running into trouble.

time to market is important, companies such
as Cognex have begun strategic alliances
with camera manufacturers.
Started in January this year, the Cognex
alliance now has 10 members including
Allied Vision Technologies, DALSA, Point

these companies do not (yet) offer smart cameras, Sony now offers VisionPro from Cognex
as an option on its XCI

Capitalizing on the growing trend toward
embedding software in smart camera products, companies that presently only develop
machine-vision software have also ported
their software to smart cameras. _______
Halcon 9.0
software from MVTec Software also runs on
_____
Sony’s XCI-V100/C and XCI-SX100/C and, by
using Windows XP Embedded in the camera,
application development can be performed
either in the smart camera or on a PC. This
can be done using MVTec’s Integrated Development Environment (IDE) that allows developers to build image-processing solutions fast
while acquiring images (see Fig. 4).
In addition to running on Sony smart
cameras, Halcon is supported on the ____

__________
also performed initial performance measurements of Halcon 9.0 running on smart
___
cameras from Vision Components.
_____________________
Despite the large number of cameras
available, the number of companies currently offering smart camera products is still
relatively small. Perhaps the main reason
for this is the cost of embedding sensors,
FPGAs, on-board processors, memory, and
interfaces into standalone systems. However,
with miniaturization on the upswing, it will
become increasingly easy for camera manufacturers to develop ever smaller smart cameras at lower cost.
To compete, companies that currently support limited software capability with their
camera offerings may be forced to develop
more sophisticated programs. Those companies that only offer machine-vision software on their own camera products may also
move toward deploying this software across
cameras from multiple vendors. Likely as not,
a meeting of both of these approaches will
occur, providing a boon for software developers and system integrators alike.

Camera Link units come in two- or four-tap models
The AViiVA II camera series features sensors with resolution up to 4k pixels with various pitches. Available with Camera Link interface in either four or two
taps, the camera delivers 68-dB dynamic range with up to 160MHz operation in standard format (higher speeds available for custom versions). The first releases will be the
EM2 CL series two-tap Camera Link and the EM4 CL
series four-tap Camera Link models. They maintain the
mechanical footprint of the current AViiVA models—
specifically the 56 × 60-mm front face.

Lens optimized for use with up to 1.3-in. sensors
The APO-Xenoplan 2.0 24-mm lens is designed to perform with
Kodak 4-Mpixel microlens-based sensors. The angle from light
farther and farther from the sensor’s center will strike the microlenses at nearly the same angle and produce equal illumination
across the entire sensor. This eliminates off-axis shading caused
by employing conventional C-mount lenses. The 24-mm lens is
optimized to cover the 1.3-in. C-mount format and can be used
on smaller formats that do not contain the microlenses.

A glowing future
The advances in electronics integration in consumer products can help machine-vision system
designers—if they are willing to tear into the details
Ever since I was young, I have always liked
taking things apart, and my father, being a
mechanical engineer, was only too willing
to encourage me in my endeavors. And so
in 1979 when his expensive wooden cabinet-sized tube-based stereo system failed, I
decided to attempt to repair it.
After my brother and I lifted the cabinet to
the center of the living room, I unscrewed the
stiff card backing of the machine and peered
inside. There, in a large metal chassis was
an array of valves that stood proudly in shiny
round sockets.
I instructed my brother to turn the equipment on while I watched to see what happened. During the next few moments, the
glass valves began to warm up and emit their
eerie orange glow. That is, of course, all but
one. This, I thought must be the culprit so,
after turning off the stereo system and letting
it cool down for ten minutes, I removed the
valve in question.
Being a member of the press, I then tried
to leverage my contacts at Philips to obtain
a free sample of the Mullard valve in question. After being informed that Philips had
not made the product for more than ten years,
I was told that they could be obtained from a
small company in India. My contact generously offered to obtain the product for me and
ship it to my dad’s house. I was delighted.
Several weeks later, a package arrived at
the door from Philips. Excitedly, I opened
the package and gazed upon the shiny new
device. Following the same procedure as

before, I located the socket of the defunct
tube and placed in the new one.
To my delight, after switching the stereo
system on, the voice of a BBC newscaster
sprang from the speakers. Without engineering drawings, signal generators, or oscilloscopes, I had brought the stereo back from
the dead. Even my old man could not believe
it. In the decades that followed, valves were
replaced by discrete transistors, transistors by
TTL logic, and TTL logic by microprocessors,
VLSI devices, and gate arrays. And, of course,
everything is now smaller. In the machinevision industry, for example, system integrators can now purchase a smart camera replete
with sensor, CPU/DSP, memory, interface,
and on-board software for less than $2,500.
System integration par excellence
Nowhere, however, has this level of integration been more significant than in the development of consumer products. To develop
products such as mobile telephones, MP3
players, and portable televisions, engineers
use sophisticated electronic and mechanical
CAD packages rather than data sheets and
drawing boards.
Using these packages, it is possible to
cram more technology into a single square
inch than ever before. And, if well designed,
these products are less expensive, more reliable, and longer lasting than any valve-based
system could ever expect to be. For those
tasked with repairing such devices the task is
more complex. More than likely, should the
devices fail under warranty, they are replaced
free of charge by the manufacturer.
Today, it has become more expensive to
repair these devices than replace them with
new ones. Although this is not yet the case in
much of the machine-vision industry, those
developing products for this market are also
concerned with reducing cost and size.
To gain an advantage in this area, inquisitive engineers may want to take a look at what
their counterparts have accomplished in the
consumer market. Although purchasing
every latest miniature device, tearing it apart,
and characterizing each design may not be
a wise idea, companies such as Portelligent
(Austin, TX, USA; www.teardown.com) have
emerged that can provide this data for you.
Replete with external and internal photographs, parts lists, component counts, and
a manufacturing cost analysis, the reports
could provide you with just the edge you
need when developing your next product.
And you will not need a screwdriver, signal
generator, or an oscilloscope—just a check
or credit card.
