Embodiment Construction

[0034] It can be seen from the background technology that the accuracy of the current detection results still needs to be improved.

[0035] In product surface quality inspection, image processing is usually used to identify defects on the product surface. Specifically, a template matching algorithm is used to make a difference between the template image and the image to be processed, so as to realize product defect detection.

[0036] The object to be tested includes a plurality of unit structures arranged periodically and cutting lanes between the unit structures. Correspondingly, the image to be processed includes a plurality of periodically arranged unit images and the cutting lane area between the unit images.

[0037] However, the kerf area in the image to be processed is easy to cause interference to the defect detection structure. Specifically, the pixel value difference between the pixel points of the kerf area and the pixel points of the unit image is large, so that...

Abstract

The invention discloses a detection method, a detection device, equipment and a storage medium, and the method comprises the steps: carrying out the cutting channel and unit pattern filtering processing or cutting channel avoiding processing of a to-be-processed image according to the size of a unit image in the obtained to-be-processed image, and carrying out the cutting channel and unit pattern filtering processing or cutting channel avoiding processing in a subsequent detection process of defect pixel points. And the interference of the cutting channel region on the detection result is eliminated, so that the accuracy of defect pixel point detection can be improved, and the accuracy of defect detection can be further improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a detection method, a detection device, equipment and a storage medium. Background technique [0002] With the continuous development of technology, precision machining is used in more and more fields, and at the same time, there are higher and higher requirements for machining accuracy. [0003] In order to meet the requirements of processing accuracy and improve the pass rate of products, it is necessary to carry out online inspection of products. For example, through defect detection, to determine whether there is a defect in the product, and to detect the position and size of the defect to ensure that the relevant indicators of product manufacturing are met. Require. [0004] However, the accuracy of the current detection results still needs to be improved. Contents of the invention [0005] The problem to be solved by the present invention is to provide a detection method...
