Paper Abstract

This paper describes a machine vision dedicated to the dimensional control of power capacitors. The geometry of these pieces is parallepipedic. This system is in keeping with the category of the active vision systems. It is built with two cameras and a LCD projector. This one will be used to determine the deformation of the parallelepiped. The calibration of the system is done with the Faugeras-Toscani's method. The set of points for the calibration is obtained by detecting the corners of the black squares on the 3D pattern. For this, we have used a technique based on the Harris corner detectors. The LCD projector is calibrated by using the last calibration. It is used to determine the deformation of the parallelepiped. The capacitor is held on a rotating table and we examine it from all sides. So we can find all the points of interest of the capacitor. Detected points are stored and will be used to give the dimensional measure. In the beginning of the process, an operator enters the references of the capacitor and the dimensions that he wants to control. All the dimensions of the capacitors produced are stored in a data base. It's easy and quick to check if these measurements are in adequacy with the specifications.
