A design scheme of machine vision measurement system to actuator ring was proposed based on computer visual examination principle. According to structure and quality requirement of actuator ring, the hardware device of vision measurement system was constructed with LED backlight, and the ring images were captured by CCD industrial camera and telephoto lens. The ring imaging was processed by means of HexSight processing software. The results show that the defect and numbered information of ring for example edentulous and die numeration was judged accurately by used of the measurement system. The measuring accuracy of measurement system can realized 0.03mm, and being simple structure and operation. The system basically meets the measurement requirements.
