The invention discloses an image difference detection method and device and a computer readable storage medium, and the method comprises the steps of obtaining a to-be-detected image and a reference image, the to-be-detected image and the reference image being images shot in the same scene at different moments; performing feature extraction on the to-be-detected image and the reference image by using a difference feature extraction network to obtain a first feature map of the to-be-detected image and a second feature map of the reference image, wherein the difference feature extraction network is obtained by training an intervention sample, and the intervention sample comprises an image sample and an interference sample carrying image background information; and performing feature comparison on the first feature map and the second feature map to obtain image difference information of the first feature map and the reference image. In this way, the accuracy of image difference detection can be improved.
Description
technical field [0001] The present application relates to the field of image processing, in particular to an image difference detection method, a detection device and a computer-readable storage medium. Background technique [0002] As the degree of automation in industry grows, the quality requirements for discrepancy detection work continue to increase. The existing image difference detection methods are not effective in some scene detection, it is difficult to overcome the background interference in specific scenes, and it is easy to cause missed detection and false detection. Contents of the invention [0003] The technical problem mainly solved by this application is to provide an image difference detection method, a detection device and a computer-readable storage medium, which can improve the accuracy of image difference detection. [0004] In order to solve the above technical problems, a technical solution adopted by the present application is to provide an image...
