Method and device for managing information of lost person

Abstract

The present invention discloses a method and a device for managing information of a lost person. The method comprises: acquiring a first to-be-searched image containing a human face of a first to-be-searched object; performing human face recognition on the first to-be-searched image to obtain human facial feature information of the first to-be-searched object; searching in a known lostness image collection stored in a known lostness database for a particular known lostness image, wherein a similarity between human facial feature information of a particular known lost person corresponding to the particular known lostness image and the human facial feature information of the first to-be-searched object is larger than a similarity threshold; determining whether the particular known lostness image exists according to a search result, and if the particular known lostness image exists, determining the first to-be-searched object is the known lost person, and if the particular known lostness image does not exist, determining that the first to-be-searched object is not the known lost person. According to the method and the device provided by the present invention, fast search and accurate identification of the lost people can be realized.

Now, although the Ministry of Public Security and people from all walks of life have carried out rescue work for lost children, the existing rescue work is usually based on the comparison of genetic information (that is, DNA), which takes a long time, costs a lot, and is easy to implement The number of lost children who were disturbed by criminals and finally successfully recovered is not many

For most of the existing lost children database systems, they usually only provide simple search functions based on names, lost locations, etc., but do not provide search functions based on faces, so the search efficiency is low, and the entered children’s photos are only It can be used to show that it is very difficult to find lost children through their photos
