    EXTRACT OF THE INTRODUCTION:

    "[This] is a list of observations, comments, suggestions, etc ... based upon our direct and our colleagues' experiences. It is offered in a light-hearted manner, but encapsulates some important lessons that we have learned but which are unfortunately not universaly acknowledged. We hope it is will bring enlightenment and promote discussion among our colleagues.[...]"

VISION SYSTEMS - The Standards

Genicam | EMVA 1288

 

GENICAM™ - Generic Programming For Cameras

"The goal of GenICam™ is to provide a generic programming interface for all kinds of cameras. No matter what interface technology (GigE Vision™, Camera Link, 1394 DCAM, etc.) they are using or what features they are implementing, the application programming interface (API) should be always the same. [...]"

EMVA 1288

"EMVA has launched an initiative to define a unified method to measure, compute and present specification parameters for cameras and image sensors used for machine vision applications. Application of this standard will be at the benefit of the customers of vision components component manufacturers. It will avoid misunderstanding and reduce pre and post support cycles."

"[...] The chosen parameter definitions are based on physical properties and units. The standard comprises the mathematical model behind the parameters, the measurement setup and the matching of the measurement data to the model as well as the data presentation. [...]"
