【Abstract】 In order to upgrade the inspection of injection molded part from manual to automation, an improved Canny algorithm for edge extraction of small injection molded part was proposed.After the improved Canny algorithm was compared with the traditional Canny algorithm, it was confirmed that when the improved Canny algorithm was used for edge extraction of small injection molded part, the noise resistance was significantly enhanced, and false edge can be suppressed to a certain extent, thereby improving the detection reliability of small injection molded part.更多还原
