In order to solve the problems of labor-intensive,low efficiency and accuracy in car door manual detection,designed a car door lock automatic detection system based on machine vision which consisted of hardware and software.Due to the low con-trast surface,the number of assembly parts and the complex of structure in car door lock,studied the improved distance preserving level set image segmentation algorithm and improved SIFT image matching algorithm,programmed the image processing software and system interface software.The test results show that the system hardware selection is rational,the system software is highly stable and efficient which improved the efficiency and accuracy in detection process of the car door lock with practical signifi-cance and high economic value.Meanwhile,the system can also be extended to other industrial assembly quality detection.
