The invention relates to a category label generation method and device, electronic equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: based on the target number, selecting a target image group from the alternative image set, generating a first category label for each target image in the target image group; based on the presetnumber, selecting a reference image group from the alternative image set, and obtaining a first accuracy rate according to the category label marked for each reference image in the reference image group, adjusting the target number according to the first accuracy rate, continuing to select a target image group from other alternative image sets based on the adjusted target number, and generating afirst category label for each target image in the target image group. According to the method, the first category label is automatically generated for the target image, manual labeling is not needed,the cost is reduced, and the generation efficiency is improved. Moreover, the target images are selected from the alternative image set by adjusting the number of the targets, so that the accuracy isimproved.
