The project presented in this paper is to develop a prototype of a 3D scanner/tracer laser with stereoscopic vision.This device has the capabilities to automatically acquire templates for cutting materials and reproduce these materials.Both aspects are addressed in this article. The first is the description of the electronic architecture of this system. The second aspect deals with image processing algorithms developed to consider the use of two cameras, to detect areas for future cutting templates and to allow camera calibration by Harris detection. For cutting templates, Hough transform was used in order to automatically detect borders of planes in a picture.
