Computer vision based technique for online monitoring of blank geometry in sheet metal forming processes

Résumé

The objective of this research is to develop a computer vision technique for online monitoring of blank geometry in sheet metal forming processes. An on-line machine vision system is presented. The acquisition system includes a camera and a diffuse illumination system. Camera and illumination have been mounted in the metal forming device to monitor de displacement of tracking elements. The acquired images are processed in order to assess the current position of the tracking elements.
