Abstract

The invention relates to a pen electric shell defect rapid detection algorithm, which comprises the following steps: respectively collecting a to-be-detected image of a to-be-detected pen electric shell and a standard template image of a defect-free pen electric shell, intercepting partial images for comparison in the to-be-detected image and the standard template image, and converting the partial images into a two-dimensional array containing gray values; correspondingly projecting a part of the image intercepted to the standard template image into an image to be detected through coarse positioning and accurate positioning, performing sum-difference operation to find out different positions in the part of the image, and finally performing traversal comparison to obtain a target image. Whether the to-be-detected image of the to-be-detected pen electric shell is different from the standard template image of the defect-free pen electric shell or not can be found out, so that whether the notebook computer shell has defects or not is automatically judged, and the defect detection efficiency of a notebook computer shell is improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a fast detection algorithm for defects in a laptop case. Background technique [0002] During the assembly process of the notebook computer, it is necessary to judge the integrity of the notebook computer shell, otherwise it is easy to cause the parts to not be assembled during the assembly process, resulting in damage to the parts and the shell during the assembly process. Therefore, in the notebook computer assembly process, it is necessary to first Inspect the case of the laptop for defects. [0003] However, the existing inspection methods rely on human eyes to judge, and the inspection efficiency is low. Contents of the invention [0004] In view of this, the object of the present invention is to provide a fast detection algorithm for the defect of the notebook computer case, so as to improve the efficiency of defect inspection of the case of the notebook comput...
