Abstract

The invention discloses an image processing method and system based on machine vision, and relates to the technical field of image processing. The method comprises the following steps: acquiring an RGB image; carrying out gray processing on the obtained RGB image; removing the background and extracting an R-B difference grayscale image as a target image; processing pixel points in the target imageto obtain an image detection area: extracting a reference image of the target image by using a deep neural network in machine vision, and processing the sub-target image and the reference image in the detection area to obtain a binary image of the sub-target image and the reference image; and calculating a binary image of the reference image and a binary image of the sub-target image by utilizinga deep neural network in machine vision to carry out difference operation, obtaining a defect value, and carrying out image defect judgment. By means of the technology, the image processing efficiency of machine vision is effectively improved, and the time of research and development personnel is saved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image defect detection method based on machine vision. Background technique [0002] Machine vision inspection refers to the technology of shooting an object through a camera, and then processing the captured image to detect the characteristics of the object, and then obtain the quality of the object. [0003] Machine vision inspection is more and more widely used, mainly in dimension measurement and appearance defect detection. Among them, appearance defect detection plays a decisive role in improving the quality of the entire product. [0004] At present, when machine vision processes images, it needs to process the entire image, and no effective feature area can be obtained; in addition, machine vision processing image calculations is complex, and the image processing speed is relatively slow. Contents of the invention [0005] In order to solve the above probl...
