Your application defines the requirements for the interface

Speed of the interface

Cable length needed

Cost of the interface

How important is data integrity

Plug and play set-up

Can the PC accomodate an additional frame grabber card

Need to network the cameras

Number of interface ports available on the PC

CONSIDERATIONS SELECTING THE INTERFACE

Standardised connectors & cables suitable for industry

Standardised camera control

Standardised integration with a range of software

Ability to migrate between manufacturers

Ability to migrate between interfaces

WHAT SHOULD A CAMERA I/F STANDARD DELIVER

12

Before 1995 there were no standards for Machine Vision and only two interfaces

LVDS

Analogue

CAMERA INTERFACING BEFORE STANDARDS

13

Physical Standards

Machine Vision Camera - On the Wire Standards

Umbrella Software & Control Standards

UNDERSTANDING STANDARDS

14

1995 to 2005 there was one standard plus two consumer interfaces

Cameralink

IEEE1394/Firewire, USB 2.0

All were physical standards

EARLY MV INTERFACING STANDARDS

15

2005 saw the development of GigE Vision

First on the wire standard

This drove the start of the umbrella standard, Gen<i>Cam

THE FIRST ON THE WIRE STANDARD

16

Separate from generic Ethernet

Power, Control & Data

GEVision – 100 Mbyte/s 100 m

GEVision LAG 200 MByte/s 100m

Gen<i>cam camera control compliance

Standard on the wire

IEEE 1588 PTP synchronisation

No trigger through the interface

Networkable

CVB Camerasuite – Image Manager for GigE Vision Cameras

Provided free with all GigE Vision cameras from STEMMER IMAGING

Will expand to USB 3 Vision when ratified

CVB Image Manager

Same API for any Gen TL supported interface

Same API for proprietary and manufacturer specific interfaces

Can expand with machine vision tools using CVB foundation

IF FLEXIBILITY IS IMPORTANT

36

Featuring the wide range of hardware supported by Stemmer Imaging using CVB

Standard and non standard

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 Gen<i>cam compliant camera solution

Provided free with cameras from STEMMER IMAGING

INTRODUCING CVB AQUISTION ENGINES

37

For the integratorFlexibility to change interface and camera manufacturerDeveloped by a supplier who is active on all standards commitees

For the application developerLicence support for all interface types and GenTL in your application or library.

For algorithm developersPlatform to market & sell your tool with a wider marketing base

For the hardware camera manufacturerLicence a high quality SDK with proven customer base.

ADVANTAGE OF USING CVB

38

Cable length and data rate often defines the interface to be selected

Consider you needs before choosing software SDK

Camera Manufacturers SDK ties you in to camera vendor

Frame Grabber SDK ties to to interface supplier but camera independence

GenTL allows choice of interface and camera manufacturer

On the wire standards allow easy change of camera if SDK is not tied to camera

Host based interfaces will encroach performance of direct interfaces

Direct interfaces offer more advanced features and via cable triggering
