Problems solved by technology
However, due to the limitation of installation location, angle and other factors, key parts of the gait data information collected by a single camera are easily missing, which greatly reduces the accuracy of gait recognition
The gait library generated by the target gait features collected by a single camera cannot be effectively applied to other camera scenes, which greatly restricts the application ability of the gait library

The present invention relates to a method and system for constructing a gait library in a multi-camera environment. The method includes the steps of: determining the number of cameras and the coverage angles of each camera on a target, so as to ensure that the target is fully covered by multiple cameras; Extract the target gait information, and compensate each other for the missing information; after each camera is compensated, adjust the weight of each camera to obtain the compensated general eigenvalue, and use the compensated general eigenvalue to realize the gait of the target The information is extracted to form a gait library. Through the method and system of the present invention, a more accurate gait library can be established, and the application scenarios of the gait library can be expanded.
Description
technical field [0001] The invention relates to the technical field of gait recognition, in particular to a system and method for building 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, when the tracked target commits a crime, he will deliberately cover his face, avoid looking directly at the camera, or move away from the camera to blur the captured video, making it difficult to identify his identity. The camera can also collect human gait information, including height and posture, behavior habits, limb defects, etc. At present, the extraction and recognition of gait features and the design of gait library are still in their infancy, mainly involving the gait feature extraction of a single camera. However, due to the limitation of installation location, angle and other factors, key parts of the gait data information collected by a single came...
