Abstract: Provided are a defect detection method and apparatus, and a computer-readable storage medium. Specifically, the method includes: obtaining a to-be-detected image; obtaining a feature map of the to-be-detected image based on the to-be-detected image, where the feature map of the to-be-detected image includes a feature map of spatial position coordinate information; and performing defect detection on the to-be-detected image based on the feature map of the to-be-detected image. By modifying a neural network structure of defect detection and extracting the feature map of spatial position coordinate information during the detection, this application makes the neural network for use of defect detection sensitive to a spatial position, thereby enhancing sensitivity of a detection neural network to the spatial position, and in turn, increasing accuracy of detecting some specific defect types by the detection neural network, and increasing accuracy of defect detection.

Abstract: Disclosed, in one embodiment, are a method and device for detecting imaging consistency of a system, and a computer storage medium. The method includes: determining a target region in an image acquired by the system, where the target region is a partial region that includes a target object in the image acquired by the system; obtaining first image information of the target region; and detecting the imaging consistency of the system based on the first image information. By obtaining the first image information of the target region in the image acquired by the system and determining the imaging consistency of the system based on the first image information, this application can effectively detect the imaging consistency of the system and improve accuracy of product detection.
