Abstract

The invention belongs to the technical field of safety monitoring, and particularly relates to a human body gait recognition system based on millimeter wave radar. The system comprises a millimeter wave radar subsystem, a data processing subsystem, a feature database subsystem, a classification and recognition subsystem and an interactive interface subsystem. The millimeter wave radar subsystem isused for transmitting and receiving millimeter waves to obtain digital intermediate frequency original data containing human body gait information; the data processing subsystem is used for performing digital signal processing on the original data to extract radar features; the feature database subsystem is used for storing and updating a feature data set of the set gait; the classification and recognition subsystem is used for carrying out gait classification and recognition by utilizing a traditional classification method and a deep learning method; and the interactive interface subsystem is used for interactively controlling and displaying a gait recognition result. The method focuses on gait characteristic analysis of indoor and outdoor human bodies, and is suitable for human body walking state analysis, walking characteristic recognition, identity recognition and the like in intelligent home and intelligent safety and protection scenes.

Description

technical field [0001] The invention belongs to the technical field of security monitoring, in particular to a human body gait recognition system based on millimeter wave radar. Background technique [0002] In the field of security monitoring, the existing main monitoring recognition technology is based on camera monitoring and recognition. However, cameras are easily affected by lighting conditions and occluders, have poor concealment, are easily damaged, and are not suitable for privacy-sensitive scenes. [0003] Gait recognition is a non-contact biometric recognition technology, which can be used for identity recognition and walking characteristics analysis through people's walking posture habits. Compared with other biometric identification technologies such as fingerprint recognition, iris recognition, and face recognition, gait recognition has the advantages of non-contact, long-distance and not easy to disguise. The feasibility of gait recognition technology comes f...
