Abstract

The invention relates to a gait database construction method and a gait database construction system under a multi-camera environment. The method comprises the following steps of determining the number of cameras and the coverage angle of each camera to the target to ensure that the target is completely covered by a plurality of cameras; using each camera to extract the gait information of the target and compensating each other for the missing information; after each camera is compensated, adjusting the weight of each camera to obtain the compensated general eigenvalue, and extracting the gaitinformation of the target by using the compensated general eigenvalue to form the gait database. Through the method and the system of the invention, a more accurate gait database can be established,and the application scene of the gait database can be enlarged.

Description

Technical field [0001] The invention relates to the technical field of gait recognition, in particular to a system and method for constructing a gait library in a multi-camera environment. Background technique [0002] Traditional video analysis is to carry out identity recognition by extracting facial features. However, the tracked target will deliberately cover the face, avoid the camera and look straight away or stay away from the camera to blur the captured video, making the identity difficult to identify. The camera can also collect human gait information, including height and posture, behavior habits, and physical defects. At present, the extraction and recognition of gait features and the design of the gait library are still in their infancy, mainly involving the extraction of gait features from a single camera. However, due to the limitation of the installation location, angle and other factors, the key part of the gait data collected by a single camera is easily missin...
