The invention discloses an image difference detection method and device. The method is applied to an integrated circuit, and comprises the following steps: preprocessing a collected sample image; constructing a difference detection model based on a neural network; performing model training on the difference detection model according to the preprocessed sample image to obtain a target difference detection model; and detecting the to-be-detected images according to the target difference detection model, determining difference information between the to-be-detected images, and determining abnormal image data according to the difference information. According to the technical scheme of the embodiment, the image difference is detected through the target difference detection model constructed by the neural network, the efficiency and accuracy of mass image difference detection can be improved, and finally the extraction rate and accuracy of a super-large-scale digital circuit are greatly improved. 本发明公开了一种图像差异检测方法和
