Problems solved by technology
[0003] The embodiment of the present invention provides a method for generating representative pictures of archives, which can solve the problem that the representative pictures of existing archives are relatively single, and cannot provide more accurate and comprehensive judgment basis for picture filing, resulting in low recall rate and low accuracy rate of picture filing. Thereby improving the recall rate and the beneficial effect of the accuracy rate of image archiving

The embodiment of the invention provides an archive representative picture generation method and device and electronic equipment, and the method comprises the steps: obtaining a face attitude angle ofan archived picture in an archive, and the archived picture being an archived picture, except for an existing representative picture, in the archive; comparing the face attitude angle with a preset attitude condition, and judging a face attitude type of the archived picture according to a comparison result; judging whether a representative picture corresponding to the human face posture type exists in the file or not based on the human face posture type; and if the representative picture corresponding to the face posture type does not exist in the archive, determining the archived picture asa newly added representative picture of the archive. According to the invention, representative pictures of various face pose types can be set for the archives, so that a more accurate and comprehensive judgment basis is provided for picture archiving, and the accuracy and recall rate of picture archiving are improved.
Description
technical field [0001] The present invention relates to the technical field of archives management, in particular to a method, device and electronic equipment for generating representative pictures of archives. Background technique [0002] Clustering and archiving the captured photos, and further analyzing valuable information that can improve the efficiency and effectiveness of public security in a certain area based on the archived information is becoming an important research direction. When a new picture is connected to the system, its feature value is compared with the feature value of the representative picture in the existing archives to calculate the similarity, and then determine whether to file based on the similarity and some decision strategies. In the existing file aggregation methods, each existing file generally has only one representative picture, which mainly comes from real-name information such as ID photos, or non-real-name pictures with better quality. ...
