Abstract

In this article a measuring system based on artificial vision techniques is described. Even if this problem is not new, several aspects, including sub-pixel algorithms, system programming and lighting, that are addressed in this paper, are still under study. Among them, the vision system calibration is focused. The theoretical model and the practical details of a fast method for 2-D problems are described, by comparing 3-D techniques already in the literature. The main features of the developed system are: cheap and easy to use. An example application is provided for the overall performance assessment.
