Abstract

The invention discloses a printed circuit board defect image registration method, device, equipment and storage medium. The method includes: obtaining a product picture and a preset template picture of a printed circuit board; Points are matched with the corresponding non-deformable key points in the preset template image to determine several non-deformable registration positions; several deformable key points in the product image are matched with the corresponding deformable key points in the preset template image, to determine a number of deformable registration areas; perform image transformation on the product picture according to the number of non-deformable registration positions and the number of deformable registration areas, and obtain a defect registration image of the printed circuit board. The invention reduces the influence of interference factors and improves the accuracy of defect registration images by separately matching non-deformable key points and deformable key points.

Description

technical field [0001] The present invention relates to the technical field of defect detection, in particular to a method, device, equipment and storage medium for defect image registration of printed circuit boards. Background technique [0002] When classifying the defect images of printed circuit boards, it is necessary to register the defective product images generated in real time with the template images drawn according to the design files to obtain registration images, so as to classify the defect images according to the registration images , the accuracy of the registration image determines the accuracy of the defect image classification. The existing image registration methods are greatly affected by interference factors, resulting in low registration accuracy. Therefore, how to improve the accuracy of image registration has become an urgent technology to be solved. question. [0003] The above content is only used to assist in understanding the technical solution...
