Embodiment Construction

[0052] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0053] refer to figure 1 As shown, a behavior recognition system based on sub-action perception of the present invention includes: a wearable terminal, a cloud processing server and a communication device;

[0054] The wearable terminal is used to collect inertial sensor data. If the local processing capability of the wearable terminal is sufficient (that is, the wearable terminal can recognize the user's movement locally), the user's movement will be recognized locally. If the local processing capability of the wearable terminal is not enough, then Forward the data to the cloud processing server for processing;

[0055] The communication device is used to process the information transmission...

Abstract

The invention discloses a behavior identification system based on sub-action perception and a work method thereof. The system comprises a wearable terminal used for acquiring inertia sensor data, if the wearable terminal has sufficient local processing capability, a behavior identification algorithm based on sub-action perception operates, action of a user is identified, if the wearable terminal has insufficient local processing capability, data is forwarded to a cloud processing server for processing; communication equipment used for processing information transmission between the wearable terminal and the cloud processing server, and the cloud processing server used for acquiring the inertia sensor data acquired by the wearable terminal in real time, the behavior identification algorithm based on sub-action perception operates, and user action is identified. The method is advantaged in that accuracy generally does not decrease when action of a new user is identified, problems caused by customized user action can be excellently solved, required training data is small, training cost is small, an identification speed is fast, calculation is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of behavior recognition, in particular to a behavior recognition system based on sub-action perception and a working method thereof. Background technique [0002] Behavior recognition technology refers to the technology of recognizing human actions through algorithms such as mathematics and pattern recognition. Behavior recognition has a wide range of applications in motion detection, human-computer interaction, healthy life guidance, and monitoring of the elderly and children. With the development of society, people's health needs are also increasing, which also makes the role of behavior recognition more and more important. more and more important. In recent years, with the gradual popularization of smart bracelets and smart watches, new opportunities have been provided for behavior recognition; wearable terminals basically integrate various inertial sensors, such as acceleration, gyroscope, magnetometer ...
