Abstract

The invention relates to a defect detection method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: carrying out graying processing on a to-be-detected image to obtain a grayscale image; determining gray scale information of a background in the gray scale image and gray scale information of a target object in the gray scale image according to the gray scale value of each pixel point in the gray scale image; performing ternary processing on the grayscale image according to the grayscale information of the background and the grayscale information of the target object; and determining defect information in the to-be-detected image according to a ternary processing result. According to the embodiment of the invention, the defect detection precision of the image can be effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a defect detection method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Defect detection usually refers to the detection of surface defects of objects. Surface defect detection uses advanced machine vision detection technology to detect defects such as spots, pits, scratches, color differences and defects on the surface of workpieces. Defect detection can be applied to items that have strict requirements on appearance and clear indicators, such as metal surfaces, glass instant noodles, paper surfaces, and electronic component surfaces. [0003] The current defect detection technology is mainly based on the defect detection model to realize defect detection, that is, collect a large number of defect training samples in advance, perform binary processing on the defect image to obtain a binary image, and then ...
