Human body movement recognition system based on acceleration sensor and method

Abstract

The invention relates to a human body movement recognition system based on an acceleration sensor, comprising a computer, a plurality of information acquisition subsystems and a main control machine, wherein the information acquisition subsystem and the main control machine are respectively worn on a human body; the main control machine controls the information acquisition subsystems to acquire human body acceleration information and transmits the human body acceleration information to the computer for analysis; the information acquisition subsystem and the main control machine carry out data transmission by a communication mode of wireless radio frequency, thus avoiding inconvenience and uncomfortableness of excessive wires caused by electric connection; even under the lightless condition, only a user carries out movement of relevant modes, the movement of the user can be recognized, therefore, the human body movement recognition system is less influenced by the ambient environment, and has stronger adaptability; and the movement in each movement recognition mode can be adjusted dynamically, a certain movement can be deleted or added, therefore, the user can add or delete the movement to be recognized according to his / her own needs, thus improving the adaptability of the product.

Description

technical field [0001] The invention relates to the field of sensor applications, in particular to a human motion recognition system and method based on an acceleration sensor. Background technique [0002] Human action recognition technology is an important research direction in robotics research, and it has become an indispensable technology to improve people's daily life. It can recognize user actions and intentions without the help of traditional input devices of any computer system. In recent years, the use of computer technology to identify human body movements has attracted much attention in the field of computer vision. People use video means to track and capture human body movements, obtain human body movement parameters and reconstruct human body structure and posture from the movement. The ultimate goal is to To understand and apply human movement behavior. It is mainly used in intelligent monitoring, virtual reality, advanced user interface, motion analysis, mod...

AI Technical Summary

Problems solved by technology

However, it is mainly for the auxiliary analysis of the accuracy of the athlete's movements, and fails to process the acceleration data, dig deeper, and establish a motion model related to acceleration. Because it is mainly used in competitive sports, according to the acceleration and The direction evaluates the completion effect of the athletes' movements during the exercise process, so it is not its function to recognize the movements of the human body; moreover, it mainly realizes the electrical connection between the collector and the controller through wired methods, which is inconvenient to use

Undoubtedly, the scope of application of this invention is greatly reduced by the method used in the acceleration test device for distributed human motion links.
