| Abstract: This research studies the production line of detecting gear defects by using machine vision based on OpenCV. The real-time images are obtained by CCD (Charge-Coupled Device) industrial camera. After preprocessing the gear with grayscale, ltering, binarization and morphological operation based on OpenCV, the in uence of background image is eliminated, and the clear gear pro le is obtained. Then, the gear pro le is screened to detect the teeth, and the positions of the defective gears are transmitted to the SCARA (Selective Compliance Assembly Robot Arm) manipulator, which picks up the defective products. In this way, the automatic detection of gears is realized through combining machine vision algorithm and the manipulator. |
