In this issue of Imaging & Vision, we are focusing on a more detailed technical content. Among other things you can read about the pros and cons of the different interfaces and how the line scan cameras with GigE interface works.

But of course we are also, as always, launching a lot of new products. Matrox expands their family of smart cameras with a 5MP high-resolution version and they took at the same time the opportunity to add color features in Design Assistant, the integrated development environment.

From our supplier of LED illumination, Advanced Illumination, we present some new products. A range of interesting ring lights expands their already broad portfolio of LED lightings for industrial applications and machine vision.

Z-Laser is launching a new series of M18-lasers which you can get in a compact format, from only 76 mm length, depending on configuration.

In our previous issue we presented our new supplier of 3D cameras, Automation Technology. In this issue you can read more about their high-end cameras with GigE interfaces for 3D applications.

Enjoy your reading !

Theintegratedhigh-speedCXprocessingFPGA determines the height profile of the measured surface with a sub-pixel precisionof1/64pixelwithoutincurringany loss of speed. These outstanding characteristics enable integrators to expand their field of three-dimensional measuring solutions in a versatile way.

Applications can not only be found in the automotive supplier industry, for example usingCXcamerastotestthesurfaceprofileoftiresorrubberseals(Picture2),butalsoin the renewable energy generation sector, where solar cells are inspected for criteria

such as shape and thickness. Monitoring weld seams or adhesive beads is another typical application, as is position detection in robotics and inspection of components likeconnectionrods(picture3).

WithCameraLinkandtheGigEVisionstandard, two very common interfaces are availablefortheCXsensors.SincethecamerasarecompatiblewiththeGenICam-protocol, the integration of these sensors into applications is very simple. This means that the complicated configuration of the cameras through camera-specific libraries is already history. Now, the access to the cameratakesplacethroughsimpleXML.

The 3D cameras can be combined with lots of image processing tools available in themarket(MatroxMIL,Halcon,VisonPro,

CVB,etc.).Thisiswhyintegratorscannotonly operate with a high degree of flexibility, but also rely on an experienced flow of work. Developers can concentrade on the application solution without the need to learn another camera specific interface.

The CX Camera Series comprises the world fastest high-resolution 3D sensors

and is a revolution for three dimensional shape measurement. It offers

unique key benefits for OEMs and Vision Integrators while making 3D imaging as easy as 2D vision.

Design Assistant 2.4 – brings color to machine vision

Matrox Iris GT – now in a 5 Megapixel version

MatroxDesignAssistant2.4flowchart-based integrated development environment introduces a set of tools to identify parts, products, and

items using color, in addition to assessing quality from color and isolating features using color.

TheColorMatcherstepdeterminesthebest matching color from a collection of samples for each region of interest within an image. A color sample can be specified interactively from an image or through the use of numerical values. A color sample can be a single color or a distribution of colors(i.e.,histogram).Thecolormatchingmethod and the interpretation of color differencescanbemanuallyadjustedto

suit particular application requirements. TheColorMatcherstepcanalsomatcheach image pixel to color samples, which segments the image into appropriate elements for further analysis using other steps such as Blob Analysis.

Gigabit Ethernet - High data throughput Gigabit Ethernet is the interface with the strongest growth rate. With a cable length limitof100meters,GigEmakesthecablelength maximums for other interface technologies obsolete and offers layout possibilities that are a much better fit for wide-span systems. By adding Gigabit Ethernet switches, system complexity can be greatly reduced. The GigE data rate ofmorethan100MB/sissufficientforallmainstreamapplications.TheGenICamstandard(www.genicam.org)definesthe logical interface for machine vision applications and in combination with the GigE Vision standard, it allows very simple integration into all vision libraries. Gigabit Ethernet has the potential to become the dominant interface. It has the widest flexi-bility regarding bandwidth, cable length, and multi-camera functionality. In addition, 10-GigabitEthernetisalsotechnicallypossible.

Camera Link– Very high data throughputCameraLinkwasdevelopedespeciallyfor industrial cameras and is an extremely robust, stable, and powerful interface for industrial cameras of all classes. Due to its highdatathroughputcapacityofupto850MB/s, it is especially strong in applications with high line or frame rates and high resolutions. It requires cables with special connectors and frame grabber cards that makeCameraLinksolutionsexpensive.Gigabit Ethernet is the main competitor in mainstream applications and nowadays oftenreplacesCameraLinkbecauseofitslow costs, long cables, and flexibility.

FireWire – Moderate data throughput FireWire,orIEEE1394,hasbeenthemostsuccessful interface over the past several years. It allows a very stable connection between a camera and computer. The DCAMStandarddefinesthelogicalinterface and makes for easy integration intosoftwarelibraries.CablelengthswithFireWirearelimitedto4.5meters,butinpractice, special cables can reach up to 8 meters. Multi-camera systems are possible, but they reach their limits very quickly because all cameras share the available bandwidth, and this often causes problems with as few as two cameras connected. FireWire accessories are a bit more expen-sive than GigE devices, but much less than thoseforCameraLink.

USB 2.0- Moderate data throughput TheadvantagesofUSBcamerasaretheirvery low cost and the ease of use that everyoneknowsfromhomePCs.Theirusein industrial applications is limited. Most USBcamerasareverysimpleandhavelittle memory, making image losses quite common.TheUSBinterfacedeliversvoltage to the connected devices, but cannot guarantee a stable power supply. In addition,USB2.0camerasdonotadheretoa standard. This can cause compatibility problems with devices from different vendors.WithaUSB3.0standardonthehorizon, there is a possibility that these problems can be overcome in the future.

The topic of interface technology keeps users and manufacturers of digital cameras

busy. Until now, there has not been one interface that fits well in all applications and

that dominates all other interface technologies. However, you can see some trends.

Line Scan Cameras and GigE Interface TechnologyThere are still some critical voices about using line scan cameras with GigE Interface. These doubts are unnecessary from a tech-nologicalstandpoint.Ofcourse,forsomedemandinglinescanapplications,CameraLink is still the interface of choice, for example if very high data rates or speeds are required. But for mainstream appli-cations, you are on the safe side with state-of-the-art GigE cameras such as the Basler runner that provide several benefits:

•GigEtechnologycaneffectivelytransmitaround100megabytesofdatapersecond.This lets you achieve line rates for 1k and 2 kcamerasthatarecomparabletoCameraLink based cameras.•Withthemaximumcablelengthof100meters, image data transmission over long distances is easy.

Gigabit Ethernet offers layout possibilities that are a much better fit for wide-span systems. By adding Gigabit Ethernet switches, the system complexity can be greatly reduced.•OverallGigEsystemcostcanberedu-cedsignificantlycomparedtoCameraLinksystem layouts. Several accessories that usedtobenecessarywithCameraLinkcanbe eliminitaed. In addition, GigE accessories such as cables or switches are usually less expensivethanCameraLinkaccessories.

The most important differences compared to Camera Link are the following:

•Theframegrabberisreplacedwithanetwork adapter card. Image transmission tothesystem’shostcomputerisdoneviaa common Gigabit Ethernet port. Gene-ric GigE network cards are commercially available and widely used in consumer net-works. Specifically recommended Gigabit Ethernet cards are also available from Intel. These recommended models allow the use of a higher performance device driver and are more reliable in terms of long-term availability.Highendnetworkcardswith pre-processing functionality are also available and can be used to easily replace CameraLinkframegrabbersonaone-to-one basis.

GigE Vision standard compliant cameras ensure compatibility, reliability, and robust-ness

•Costsforcablinggodownwhilecablelengths are enhanced. Gigabit Ethernet uses standard Ethernet cables, known asCategory6(Cat6)cablesthatcanbeobtained in different shielding classes. In accordance with the Gigabit Ethernet stan-dard, GigE cables are available in lengths upto100meters.Thisisagreatenhance-mentincomparisontoCameraLink’s10meter limitation. GigE cabling offers a great potentialforloweringcosts.Astandard10meterCameraLinkcablecanbepriceduptotentimeshigherthanaCat6GigEcable.Ausermightsave100eurosormoreincabling per camera while gaining flexibility in system design.

•Theconverterboxiseliminated.Com-paredtoeitherCameraLinkoraconverterbox, Gigabit Ethernet simplifies the camera to host computer interface. The frame grabber can be eliminated and a simple Gigabit Ethernetnetworkcarddoesthejob.Taskssuch as color conversion that have been performed on the frame grabber in the past are now directly embedded in the camera. In Basler cameras, they can be activated viaBasler’senhancedpylonAPIorpylonViewer.EliminatingtheCameraLinkframegrabber represents a several hundred euro savings that can be achieved. And with a direct GigE connection, very expensive “CameraLinktoGigabitEthernetconverterboxes” are history, again saving several hundred euros.•TheinterfaceisGigEVisionandGenICamstandard compliant.

FLIRA-SeriesThermal imaging cameras for

automation and safety applicationsProduction engineers and technicians are faced by the demand for higher production output at a constant quality and at lower cost.TheFLIRA-seriesthermalimagingcameras are the most effective tool available forInfraredMachineVision,ClosedloopProcesscontrolandQualityAssuranceimaging, helping you to validate and in-crease product quality and throughput and thereby give your products a competitive edge and increased profitability.

TheFLIRA-Seriesthermalimagingcamerasare also great tools for safety applications. Safety applications exist in any industry where protection of lives and assets is of importance and where an early warning of a potential critical condition is of utmost importance.

Automation

Problems can occur at any time in a production process. In most cases, it will not be possible to see the problem with

the naked eye or to quickly spot potentially harmful temperature variations. For many applications, such as the production of parts and components for the automotive or electronics industry, thermal data are critical.

While machine vision can see a production problem, it cannot detect thermal irregula-rities. Thermography provides much more information to production specialists and decision makers. Indeed, for non-contact precision temperature measurement there is nothing to equal thermography. It adds a new dimension to machine vision and is the perfect solution for applications involving non-contact precision temperature measu-rement and non-destructive testing.

Thermal imaging cameras for automation applications

For machine vision application, fixed mountedthermalimagingcameraslikeFLIRA615/A315 can be installed almost any-where to monitor your production process by detecting and measuring temperature differences and visualize heat patterns.

Affordable, compact, and powerful, the FLIRA615providesover300,000pixelsof accurate temperature measurement data.Theworld’sfirst640×480uncooledinfrared camera to be fully-compliant with bothGenICamandGigEVisionprotocols,theFLIRA615isreadyforinstallationintocutting-edge networks right out of the box, and plug-and-play with software from machine vision providers National Instru-ments,Cognex,Matrox,MVTec,StemmerImaging, and many more.
