STEMMER IMAGING

This training is based on the directive VDI/VDE 2632 Sheet 2 (from German industrial engineering association). It forms the basis for learning how to create optimised performance and requirement specifications for machine vision systems. Consideration of all influences on the vision system, a detailed task and features description improves communication between planners and users, and assures that your projects run smoothly and will be completed faster with greater success. At the end of the course you will be able to understand the interaction of all components in a machine vision system and you will know which influencing factors you have to consider while designing and assessing your own solution.

Target audience

People new to the machine vision domain who need to specify vision systems as well as people planning to design or use machine vision systems. No prior machine vision knowledge is required.
