| description | The invention discloses a part surface defect detection method based on sequence image difference, and the method specifically comprises the following steps: firstly, selecting sequence images in the same production batch, and carrying out the registration of front and back adjacent parts; secondly, in an image registration process, carrying out sequence difference on the part image; and finally, judging whether the to-be-detected part is qualified or not. Due to the fact that errors are accumulated step by step in the silk-screen printing process, when the difference between the production sequence of a template part and the production sequence of a detection part is too large, accurate difference cannot be achieved, and therefore the part surface defect detection method based on sequence image difference is adopted. High-precision and high-stability detection of printing quality defects of parts with complex surface features based on a visual detection technology is realized.
