Gait Behavior Features Single New Identity Recognition Helps Smart Home

Biometrics technology is not new anymore. There are various ways of identification from fingerprints, face to iris, finger veins, and identification technology is constantly updated. The application in the field of security has received increasing attention. Recently, a way of identifying technology based on the characteristics of human walking gaits is being tapped. It can overcome the shortcomings of fingerprint, vein, and face recognition methods that cannot be identified remotely. The use of gait recognition in smart homes provides new impetus to the development of smart homes.

Identification principle and safety

The working principle of gait recognition is to record the gait image of the authorizer by the camera beforehand. When someone approaches, the camera automatically records the walking posture, matches and judges to confirm its identity.

In the field of intelligent monitoring, remote identification is more advantageous than close-range identification. Gait is a complex behavioral feature because people have differences in height, weight, muscle, bones, physique, individual contours and sensitivity, flexibility, and so on, which determine the characteristics of the gait, identification and uniqueness Sex!

At the level of security recognition technology, the human body feature extraction method consists of the following: based on "a human body appearance model that can be learned from a spatiotemporal pattern of walking motion", based on "the walking motion of human body largely depends on the shape change of the contour over time. "Based on the changes in joint angles of walking movements that contain rich individual identification information". Each aspect has its own implementation methods and features, and select different feature extraction methods in different contexts. Strict algorithm and feature extraction recognition ensure the safety and reliability of gait recognition.

Prospects and Applications

Intelligent monitoring will be a trend, and gait recognition plays an indispensable role in many fields. In terms of ****, the policing security camera can record the gait of passers-by and match with the back-end database to predict the identity and purpose of this person and provide feedback if necessary.

Today's popular home Internet of Things provides opportunities for gait recognition to enter the homes of ordinary people. Considering the example of the IoT community, it is assumed that when the children returning from school pass to the floor lobby, the camera confirms their identity and data through gait recognition, automatically opens the entrance gate, opens the elevator door and presets the floor, and the home lights up and starts. The TV goes to a cartoon channel, automatically sends home information to parents and so on. Strong security application features and excellent user experience vision, gait recognition prospects and applications will be very broad.
