Defect Inspection on Bearing Cylindrical Surface by Linear CCD

In view of the low efficiency and high inspect leakage rate to find the defect on micro bearing surface by manual method, an on-line automatic inspection system was developed by using linear CCD for inspecting the defect on micro bearing cylindrical surface. The system was based on the general requirement of computer vision inspection system for micro bearing defect. Several experiments were carried out to validate the effectiveness of the proposed system. The results show that it realizes the expected functions and has a high stability, real-time performance and accuracy. Thus the system can be used for actual production. [Ch,5 fig.10 ref.]
