Public person database establishment method and system based on face recognition

Abstract

The invention discloses a face recognition-based public person database establishment method and system. The method comprises the following steps of: 1, acquiring person information, processing to obtain individual person data of each person, and generating person document data; 2, obtaining figure pictures and performing multiple filtering to obtain individual figure picture data of each figure; 3, extracting face feature data of each person in the person picture data, and adding the face feature data to the corresponding person document data to generate a person data set; 4, storing the character data set into a character database; 5, inputting information data, performing multi-dimensional retrieval in the character database, and optimizing the character database; the system comprises a data acquisition module, a filtering module, a feature extraction module and a character database.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to a method and system for establishing a database of public figures based on face recognition. Background technique [0002] In the application of face recognition technology, a common application scenario is to input a picture of a public figure (such as a movie star, singer, etc.), identify the person in the picture and output some attribute information of the person in the picture (such as: gender, Occupation), in order to realize this function, it is necessary to establish a character database that stores the face information of the characters and can correspond to the attribute information of each character one by one. New public figures are constantly being generated, so a method for establishing a character database that can quickly and easily add new figures and be easily modified is required. Contents of the invention [0003] The technical problem to be solved by the pr...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the application of face recognition technology, a common application scenario is to input a picture of a public figure (such as a movie star, singer, etc.), identify the figure in the picture and output the picture of the figure. Part of the attribute information (such as: gender, occupation), in order to realize this function, it is necessary to establish a character database that stores the face information of the characters and can correspond to the attribute information of each character one by one. Due to the large number of public figures , the information is updated quickly, and new public figures will continue to be generated. The present invention provides a method for establishing a public figure database based on face recognition. The present invention also provides a system for establishing a public figure database based on face recognition, which can Screen the pictures of people to remove the pictures that cannot detect faces or detect more than one face; store the collected person information separately, one document for each person, named after the person's name; use the RetinaFace model to extract the face feature value and generate a Unique ID; store each character's facial features, ID and its character information together to create a character library; after the first character library is established, new characters can be added to the existing library at any time, with simple preparation, easy operation, The characteristics of new characters can be added at any time to solve the defects caused by existing technologies
