Abstract
This disclosure relates to the field of image processing technology, and provides an image deduplication method and apparatus for equipment security inspection. The method includes: acquiring a group of images to be deduplicated, the group comprising multiple pairs of images to be deduplicated; extracting spatial feature vectors for each pair of images in the group of images to be deduplicated based on a preset Siamese network model; calculating a similarity value between the spatial feature vectors of each pair of images in the group of images to be deduplicated; extracting color data feature vectors of images in each pair of images to be deduplicated based on the similarity value and a preset image threshold; and determining whether duplicate image pairs exist in the group of images to be deduplicated based on the color data feature vectors. This disclosure can quickly and in real-time find and filter out duplicate images taken at the same angle in the same scene, saving time and effort, increasing work efficiency, and improving the efficiency of subsequent equipment security inspection.
