Real-time human body gesture supervised training correction system based on quaternion

The invention discloses a real-time human body gesture supervised training correction system based on quaternion. The system comprises a depth-indexing video collection device used for collecting the depth image information of a trainee, a human body gesture analyzing and processing module used for analyzing and processing the main joint information of the trainee, an electrocardio information collection device used for collecting and transmitting the electrocardio information of the trainee, and a human body metal state analyzing and processing module used for obtaining the information such as nervous degree, fatigue degree and emotion change of the trainee by analyzing and processing the heart rate, the breathing frequency and the like of the trainee. The real-time human body gesture supervised training correction system based on quaternion can meet the requirements of self training, assistive training and professional teachers on carrying out digitalized correction and supervising on the metal state or functional change of the trainee in real time, and is applicable to all the fields requiring supervised training correction on a human body gesture.
