Currently 6 links aggregated downlinks Optional fast uplink channel. Can be expanded Through-the-cable trigger with 6µs latency, 10ns jitter Hot-pluggable Embraces GenICam Compulsory GenICam TL 22 CAMERALINK HS KEY FEATUES Dedicated frame grabber Copper or fibre Power, control & data 300MByte/s channel CX4 connector x7 channel plus 1 fast uplink @ 15m SFP (x1 channel) SFP+ (x4) plus uplink @ 300m Through cable trigger 300ns latency and 3ns jitter Hot-pluggable Hardware error detection and resend 32 GPIO lines with 300ns latency Data forwarding Embraces GenICam for camera control GenICam transport layer is optional 23 HOST INTERFACE EVOLUTION 24 USB3 VISION KEY FEATURES USB3 Vision sits on USB 3.0 generic interface Host based standard on-the-wire Power, control & data 400MByte/s 7.5W Power Full GenICam compliance Lockable connector 5m + cable length (3.5m current tests at full speed) 0 copy transfers supported No real-time trigger through the interface Keeps ethernet port free 25 WHAT DOES THE FUTURE HOLD 26 WHAT IS GENICAM Generic cameras interface 27 GENICAM How is GenICam Structured GenAPI – Standardised XML based control interface for cameras Genicam Standard Features Naming Convention (SFNC) for cameras GenTL – Generic transport layer from driver to application GenICam compliance standards: 28 GENICAM Picture of a scanner 29 PROPRIETORY HOST BASED CAMERAS Optional Gen TL Configuration 30 PROPRIETORY WITH GENICAM TL DRIVER Optional Gen TL Configuration 31 HOST BASED ON-THE-WIRE STANDARDS Compulsory GenICam 32 DIRECT ON-THE-WIRE STANDARDS Compulsory GenICam 33 CVB - MAKING INTERFACING EASY 34 IF FLEXIBILITY IS IMPORTANT CVB CameraSuite – Image Manager for GigE Vision & USB3 Vision cameras Provided free with all compliant cameras from STEMMER IMAGING CVB Image Manager Same API for any GenICam TL supported interface Same API for proprietary and manufacturer specific interfaces Can expand with machine vision tools using CVB Foundation Package 35 INTRODUCING CVB AQUISITION ENGINES Supporting the wide range of hardware supported by STEMMER IMAGING using CVB Standards based and manufacturer proprietory Direct support inside popular imaging applications CVB AQ for Sherlock CVB AQ for Cognex Vision-Pro CVB AQ is part of AQSense 3D Express - making 3D easy Enabling any product to support any GenICam compliant camera solution Provided free with USB3 Vision & GE Vision cameras from STEMMER IMAGING 36 ADVANTAGE OF USING CVB For the integrator Flexibility to change interface and camera manufacturer Developed by a supplier who is active on all standards commitees Option to expand to use a strong range of machine vision tools For the application developer Licence our driver to support any GenICam Provider in your application Option to expand and use a strong range of additional tools to aid development For algorithm developers CVB provides a platform to market & sell your IP For the hardware/camera manufacturer Licence a high quality SDK with proven customer base. 37 CONCLUSIONS Cable lengths and data rates often define the interface that will be required Consider your needs before choosing the software SDK Camera manufacturer SDKs ties you into the camera vendor Frame grabber SDKs tie you to an interface supplier but offer camera independence GenICam Transport Layer allows for a choice of interface / camera manufacturers On-the-wire standards allow cameras to be easily swapped if SDKs are not tied to them Host based interfaces will encroach performance of direct interfaces Direct interfaces offer more advanced features via cable triggering 38 Thank you for listening.
