Automatic Recognition System of Key Tooth Based on Machine Vision

Abstract:

Key tooth recognition is an important procedure of lock core assembly, it directly affects the assembly efficiency and qualified product rate. The current method is artificial and mechanical recognition, which has defects of mechanical loss, low precision and automatic degree. This paper proposes an innovative solution based on machine vision technology. The recognition system uses TMS320DM642 as the core processor. The image sensor MT9M001 acquires key image. The operation of image processing algorithm produces the key tooth code. Communication with the lock core assembly system uses 485-bus. The experimental result indicates that the method proposed in this paper is superior to the existing methods.
