Camera Link is a universal standard for the transmission of high speed digital images over medium distances (around 10 metres). The standard is well-established in the machine vision industry, and it is broadly adopted. A large number of Camera Link cameras are available. It is therefore important to identify and analyse the factors limiting the performance of Camera Link connections; and to consider methods aimed at compensating those limiting factors, to increase the performance of Camera Link connections.

Image analysis and machine vision have a common goal of extracting information from digital images. They differ mostly in what objects or parts they are applied to and the type of information extracted. Both use image processing - computations that modify an input image to make image elements more obvious. As examples, image processing is used to compensate for variations in lighting and to enhance the edges of objects. Machine vision is primarily concerned with locating, identifying, measuring and inspecting manufactured parts such as fasteners (bolts, screws, etc.). Image analysis is primarily concerned with measuring natural or non-manufactured parts and patterns. Applications include classifying and counting biological cells and characterising particles, textures or foams.

Commercial machine vision software is currently classified along two lines: the conventional vision library and the vision-specific integrated development environment (IDE). Determining which software is right for your vision project depends upon a variety of factors: ease-of-use, productivity, flexibility, performance, completeness, and maintenance. This white paper uses these factors to contrast the two software development approaches and clearly establish the merits and drawbacks of each. The discussion assumes that the vision tools available in both types of software are similar—if not identical—and does not explore possible discrepancies with these tools. Also, the discussion ignores the hardware platform that the vision applications run on as to not bias one over the other.

In an effort to stay ahead of the ever increasing demands of managing and controlling the world’s vast network of roads, the vehicles that use them, and the people that rely on them, transportation systems specialist are turning to computer vision for help. There are numerous software and hardware considerations that need to be considered when deploying a vision system for transportation applications. This Teledyne Dalsa white paper will focus on camera selection and matching camera requirements to various transportation computer vision applications.
