10 What is a Camera Interfacing Standard Physical Interconnect Communication Protocols Camera Control Standards include Machine Vision Standards Multimedia Standards Broadcast Standards

11 The Evolution of Camera Interfacing The early days, practical but still just a collection of ill-matched components! A modern integrated system with power, speed and flexibility Better and more integrated, but still not optimised for ease of use.

12 The Evolution of Camera Interfacing The Early Years

13 Early Interfacing Methods

14 The Evolution of Camera Interfacing The First Standards

15 CameraLink

16 CameraLink Objective Simplify the cabling and inter-connect between camera and interface Scale to support wide range of camera performances Solution Standard Cable design including serial for camera control Different configurations for different speed cameras 10 Meter cables* * Dependent on Clock Speed

17 CameraLink Configurations Base : 1 cable, up to 24 ( 3 tap), 255 Mbytes/sec max Medium : 2 cables, up to 48 bit@85mhz ( 4 tap), 510 Mbytes/sec max Full : 2 cables, up to 64bit@ 85Mhz ( 8 tap), 680 Mbytes/sec max Full+ : 2 cables 80 bit@85mhz (10 tap), 850 Mbytes/sec* *Not officially in the standard as of 2010

18 The Reality of Cable Length

19 CameraLink Evolution Initial Standard mid 1990 s Administered by the AIA Power over CameraLink option in the early 2000 s Mini connector for smaller cameras introduced early 2000 s Version 2 plans to incorporate all the enhancements CameraLink Lite for lower performance even smaller cables late Gen<i>Cam camera control Formalisation of ten tap configuration

20 IEEE-1394 (FireWire)

21 IEEE-1394 FireWire Standard Initial software used consumer drivers such as direct show IEEE trade association defined DCAM for industrial applications DCAM Defined register map and feature set. Camera Manufactures added special features outside DCAM Key Features First network protocol Deterministic data transmission 10 meter cable length (1394 a tested) 4.5m official specification

22 FireWire Evolution Mid 1990 s IEEE-1394a released Data Rate <40MByte/second Mid 2000 s IEEE 1394b released Data rate <80Mbytes/second Backwards compatible The Future Standard details S3200 providing 320MByte/s Unclear if these will materialise, slow adoption

23 USB 2.0

24 USB 2.0 Consumer Driven Interface Standard Industrial camera applications use manufacturer drivers No real standard for industrial camera interfacing The most cost effective method to add camera to computers Some manufactures have produced Gen<i>Cam drivers Cable lengths limited to 4.5meters

25 The Evolution of Camera Interfacing Now & The Future

26 Gig-E Vision

27 Gig-E Vision The Industry s second camera interfacing standard Administered by the AIA Deliver long cable lengths - 100m 100 Mbytes/second Development spawned separate camera control standard Gen<i>Cam First plug & play standard

28 Gig-E Vision Evolution 2011 sees Version 2.0 of the standard IEEE-1588 or PTP for over network synchronisation Compression LAG Link aggregation increases speed to 200 Mbytes/second Interlaced Camera support The Future Talk of 10 Gig-E Vision Power dissipation possible stumbling block Gig-E Vision is an ideal lower speed standard

29 Gen<i>Cam

30 Gen<i>Cam Initiated from the needs of Gig-E Vision Administered by the EMVA Gen API focussed on camera control Gen TL extended to deal with different transport types Provides information to control any camera receive data from an interface

31 Gen<i>Cam GigE Vision is first standard defines the use of GenAPI CameraLink v2.0 makes the used of Gen API an option Expected to be used in future camera interfacing standards CoaXpress First standard to make the Gen TL a requirement CameraLink-HS Other interface providers are delivering Gen<i>Cam Support going beyond camera control

32 Gen<i>Cam

33 Where We Are today Latest high end cameras already pushing existing standards * Technically not included in the standard

34 Moore s Law

35 2010 A Crossroads High-end GB/sec CameraLink is not fast enough Extended cable length Camera control included Mid-range up to 600 MBytes/sec Progression from CameraLink Extended cable length Cost reduction Camera control included Low-end up to 100 Mbytes/sec Gig-E Vision, Firewire, CameraLink Lite

36 What s Next CameraLink HS CoaXpress USB3 Light Peak HD-SDI HDMI HD-CCTV

37 CoaXpress

38 CoaXpress Winner of the Vision award 2009 Now being administered by JIIA Over 80 companies involved in adopter and liaison groups Specification v 1.0 beta released at vision 2010 Finalisation of standard by end of Q1 2011

39 CoaXpress Key Features Delivers up to 600Mbytes/sec per single coax cable Up to 100 meter cable length (40m at 600MBytes/sec) Scalable first interface cards to have 4 channels 4 x 600, 2 x 1200 or 1 x 2400 MByte/sec camera Single cable for power, camera control and data Trigger latency 3.4 us Embraces Gen<i>Cam Error Detection

40 CoaXpress Key Features Single coax enables: Retrofitting analogue applications Ideal for applications that require slip ring Products in development that go beyond machine vision Defence Medical Risks Single source chipset Standard requires Escrow and alternative circuit design

41 CameraLink HS

42 CameraLink HS Originated by DALSA as HS-Link Technology handed to AIA for standardisation Objectives Scales to beyond CameraLink Improve Image transmission reliability Simplified cabling & ease of use Commonly available components Timescale to standard not yet fully defined 12 members and expanding

43 CameraLink HS Key Features Range of proposed speed/ cable options Coax - up to 300 Mbytes/sec length undefined CX4 (10 GigE copper) up to 20m CX4 (10 GigE) fibre optic at SFP two core fibre 100 meters CXP Meters

44 CameraLink HS Key Features IP core can be implemented with FPGA Packet based with resend and efficiency of over 98% Real time trigger to 3.2ns latency Data forwarding built in Very Scalable X1 to X20 300MBytes/sec to 6GBytes/second

45 Summary of MV Camera Interfacing **** *On V2.0 only sync ** Technically, more cables possible *** V2 support network timing **** Error detection, manual resend

46 How do the machine vision standards compare to other camera interfacing standards?

47 Hardware The future

48 Cable Distances by Interface

49 Interfaces by Speed

50 Software Interfacing Consumer standards exist such as Direct Show and Twain Machine Vision needs device control and reliability Develop using an interface library the is Gen<i>Cam Compliant Camera and interface providers will supply compliant drivers Choose a Hardware independent SDK Supporting non Gen<i>Cam compliant interfaces Look for robust image handling and error reporting built in

51 Gen<i>Cam

52 Choose CVB The only Certified Gig-E Vision and Gen<i>Cam compliant SDK
