Abstract

The invention discloses a method and device for dynamically updating a face feature database, and a face capture system. Each face information stored in the feature base library; the face feature information of the currently captured face information is compared one by one with the face feature information of the face information in the face feature base library to generate a face similarity; When the face similarity is less than or equal to the preset minimum similarity threshold, the currently captured face information is added and stored in the face feature base library; when the face similarity is greater than the preset minimum similarity threshold and the preset When the maximum similarity threshold is reached, replace the stored face information in the face feature base library with the currently captured face information. The technical scheme of the invention can automatically update the information of the face feature base database, and improve the quality of the face photos stored in the face feature base base and the real-time update.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for dynamically updating a face feature database, a face capture system, computer equipment and a storage medium. Background technique [0002] In the existing face capture system, the specified personnel are manually photographed in advance, and the standard face photos, feature information and identity information are stored in the face feature base library to realize the initialization of the static face feature base library; Point, after the camera captures the real-time face information, it searches in the face feature base database, compares the feature information, and matches the face feature base database photos as a kind of identification. For the face capture system in the actual application of multi-channel face capture camera cascade, the static face feature base database is initialized and loaded, and the back-end platform is reli...
