【Abstract】 Binarization method is used to preprocess the target image. Median filtering method is applied to clear the image. Mathematical morphology algorithm is used to fill the defects in the target image. The central axis data of the adjacent tooth top image is extracted to realize the visual detection of the external thread pitch.更多还原
