What is a Camera Interfacing Standard

Physical Interconnect

Communication Protocols

Camera Control

Standards include

Machine Vision Standards

Multimedia Standards

Broadcast Standards


11/54


The Evolution of Camera Interfacing

The early days, practical but still

just a collection of ill-matched

components!

Better and more integrated, butstill not optimised for ease of use.

A modern integrated system with

power, speed and flexibility


12/54



The Early Years


13/54


Early Interfacing Methods


14/54



The First Standards


15/54


CameraLink


16/54


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


17/54


Configurations

Base : 1 cable, up to 24 bit @85Mhz ( 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

CameraLink


18/54


The Reality of Cable Length


19/54


CameraLink Evolution

Initial Standard mid 1990s

Administered by the AIA

Power over CameraLink option in the early 2000s

Mini connector for smaller cameras introduced early 2000s

Version 2 plans to incorporate all the enhancements

CameraLink Lite for lower performance even smaller cables late

GenCam camera control

Formalisation of ten tap configuration


20/54


IEEE-1394 (FireWire)


21/54


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


22/54


FireWire Evolution

Mid 1990s IEEE-1394a released

Data Rate


23/54


USB 2.0


24/54


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 GenCam drivers

Cable lengths limited to 4.5meters


25/54



Now & The Future


26/54


Gig-E Vision


27/54


Gig-E Vision

The Industrys second camera interfacing standard

Administered by the AIA

Deliver long cable lengths - 100m

100 Mbytes/second

Development spawned separate camera control standard

GenCam

First plug & play standard


28/54


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


29/54


GenCam


30/54


GenCam

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


31/54


GenCam

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 GenCam

Support going beyond camera control


32/54


GenCam

41/54


CameraLink HS


42/54


CameraLink HS

Originated by DALSA as HS-Link Technology handed to AIA for standardisation

45/54


Summary of MV Camera Interfacing

*On V2.0 only sync ** Technically, more cables possible *** V2 support network timing **** Error detection, manual resend

Cable Distances by Interface


49/54


Interfaces by Speed


50/54


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 GenCam Compliant

Camera and interface providers will supply compliant drivers

Choose a Hardware independent SDK

Supporting non GenCam compliant interfaces

Look for robust image handling and error reporting built in


51/54


GenCam
