Abstract

We present in this paper an image processing system to analyze and to detect some defects on metallic caps in movement with a speed of ten caps per second. We explain in detail the image acquisition method, the choice of the process parameters (in particular an edge detection parameter), the software development compatible with a micro computer (486 33 Mhz), and the working explanation of this system. We propose another solution which is more performant in words of processing time and image resolution. This solution uses an ASIC device that we have developed and which operates the real time edge detection (25 images per second). This work has been performed in relation to an industrial contract.
