| Abstract: |
| This paper proposes a computer vision-based method to detect connector pin. This method uses a high-resolution industrial camera and imaging system to take a picture of the tested electrical connector as test sample. After image preprocessing, pin feature point extraction, coordinate point registration and template comparison, etc., test sample would be compared with template in order to realize qualification judgment. A set of image measurement system was built to verify the method. The results show that the method can basically realize the automatic detection of aerospace connector pins, and the eligibility judgment successfully exceeds 98.67%, which basically meets the application requirements. |
