Image deduplication method and device and electronic equipment

The invention discloses an image deduplication method and device and electronic equipment, and the method comprises the steps: obtaining a target image of the same target object and a target data set corresponding to the target image, determining at least one target parameter meeting a preset condition in the target data set, determining image replacement data corresponding to the at least one target parameter, and storing the image replacement data corresponding to the at least one target parameter in the target data set; and replacing image data of the same type as the image replacement data in the preset data set with the image replacement data. According to the method, the image replacement data corresponding to the target image is determined through the at least target parameter meeting the preset condition, and the same type of image data is fixed in the image replacement data and the preset data set, so that the image data in the preset data set is more accurate; the accuracy of identifying the target
