Abstract. In this paper a vision-based integrated system, relying on Active Contour Models (ACM) will be presented. ACM is a popular technique for extracting the object's boundaries based on the a priori knowledge of the objectshape. The algorithm is implemented in industrial parts of circular cross-section with undefined radius. The objective of ACM is to define the boundaries of the incoming part. Based on the coordinates of these boundaries, a proposed algorithm based on Least Squares calculates the center of the part. An x-y transposition table is responsible for moving the recognized part in a predefined place, where a welding-process will take place. 1
