Problems solved by technology
The quality of the pictures collected through snapshots is uneven, blurry, incomplete, etc. If all the pictures can participate in the calculation of the file cover, it will have a negative impact on the archiving of the query pictures
In addition, although the method of using the cluster center as the file cover can avoid the adverse effects of noise data to a certain extent, the same person may change greatly due to orientation, posture, etc., and the cluster center of a single feature cannot fully represent this person. more data is needed

The invention provides a personnel archiving method and device and electronic equipment, and the method comprises the steps: scoring an image in collection data under any ID in an archive database from a plurality of different dimensions through a pre-trained scoring model, and filtering the images with the scores being lower than a preset scoring threshold value, so as to obtain a filtered image; performing feature extraction on the filtered image by using a plurality of pre-trained feature extraction models to obtain a plurality of different types of features; respectively clustering the plurality of different types of features to obtain a plurality of clustering centers corresponding to the plurality of different types of features; and generating an archive cover according to the plurality of clustering centers, and performing personnel archiving according to the archive cover. According to the method, the accuracy and recall rate of archiving can be improved.
Description
technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a personnel filing method, device and electronic equipment. Background technique [0002] In the field of video surveillance, functions such as tracking specific people and discovering strangers in the area have gradually become key requirements. By establishing a personnel file for a person whose identity is known, the person who appears in the monitoring needs to perform a file query to determine whether he is the person he is looking for or a person who is not in the file (that is, a stranger). If it is a person in the file, it will be classified under the target ID (identification), if not, it will be classified under the stranger. [0003] An important basis for judging when archiving is the similarity between the query image and the file cover. The file cover will directly affect the performance of the filing system. The quality of the pictur...
