Multi-feature extraction of contour is the key process in parts visual measurement. It is presented that a multi-feature extraction method of contours with additional constraints based on existing method to identify the composition primitives of the contour accurately, such as lines, arcs, circles, and acquire the parameter of each primitive. At last, the simulated and the actual industrial parts experimental results demonstrate that the introduction of constraint relations can effectively improve the accuracy of multi-feature extraction.
