The automatic sorting production line of automotive components based on DFK 33GX174 industrial camera is designed. Harris corner feature detection was used to identify the components and to determine the components orientation, three dimensional (3D) to locate the grab points, so as to improve the assembly precision. The actual application shows that the production line shortens automotive components sorting production cycle, which solves the key problem of automatic identification and sorting of the component orientation of parts with high requirement on automobile assembly process, what to achieve automatic detection and elimination. It has very high reliability and practicality and a certain reference value for industrial application.
