containers that are free from defects and contamination. At
high production speeds, a human operator is not able to
perform this task: high-speed cameras are the ideal solution
for such a highly automated inspection system.
For applications in the food sector, manufacturers
are turning to camera solutions like Teledyne DALSA’s
GenE Nano GigE Vision family and Adlink’s Neon
series. Teledyne’s GenE cameras combine several
advanced CMOS sensors, including Sony’s Pregius,
On Semiconductor’s Python, and Teledyne e2V’s
Saphire, Emerald to produce a highly-integrated system
that’s optimized for high speeds. Advanced processing
techniques and an improved I/O architecture allows it to
achieve data transfer speeds up to 40 percent more than
the standard GigE Vision values (Figure 2).
Teledyne also offers its Calibir series of long wave infrared
(LWIR) cameras, which offer excellent image acquisition
performance and maximum flexibility in a very compact
format. The microbolometer-based platform covers the
wavelengths from 8 to 14 μm and supports a wide range of
advanced on-board interfaces and processing capabilities.
Adlink’ Neon cameras also provide image capture
solutions for these applications. They have a quad-core
Atom processor in addition to a FPGA and a GPU that
allow a high processing speed. These components,
combined with a 32GB memory for images, provide
an ideal motor for industrial applications requiring high
speeds and high resolutions. The IP67 enclosure with
M12 connectors allows to be used even in non-aseptic
NEON-1040 cameras suit them for inspecting objects on
high-speed lines, particularly to check information on labels,
read barcodes, and perform inspection in the food industry
3D vision to grow
The global machine vision market is expected to reach USD
$19.22 billion by, according to a report by Grand View
Research, Inc. While conventional 2D vision applications for
tasks such label orientation, barcode reading and printing
verification will continue, there will be an increasing demand
for 3D vision applications that provide three-axis viewing for
more detailed inspection.
Fabio Marezza, District Sales Manager at Cognex
Corporation, said, “The future of machine vision market
mainly consists of two separate, but simultaneous, phases:
‘evolution’ and ‘revolution’ of the traditional vision systems.
“On one side, the ‘evolution’ of the machine vision market
brings more customers to leverage the benefits of 3D
vision, applying the same concepts of the traditional 2D
vision (quality inspection, measurements, robot guidance,
OCR, etc.) to a 3D image.
Marezza expects the ‘revolution’ of the machine vision
market to be the implementation in industrial environments
of Artificial Intelligence solutions. He expects 3D technology
to allow to an even more accurate analysis of the objects.
For this reason, many companies have introduced market
solutions for dynamic 3D scans and for stationary 3D image
Another trend for machine vision is to have more
compact and powerful solutions that can provide high
speed and accuracy in a compact footprint. Machine
vision suppliers such as Cognex, Teledyne, Sony, Adlink
and others are developing “Smart” solutions both for
general purpose vision applications and for automatic
identification applications. This will enable OEMs to reduce
the need to implement industrial controllers and PC-based
architectures, while maintaining high performance.
