Problems solved by technology

[0011] An object of the present invention is to overcome the defects that the existing Newton-Euler equation cannot satisfy both no-singularity and no-over-constraint in the correction of human body motion capture data, thereby proposing a method based on Euler angle-quaternion Hybrid Newton-Eulardo Rigid Body Dynamic Equations
This equation can effectively solve the problem of singularity of Euler angles and minimize the hindrance of the constraint that the quaternion modulus length is one to the optimization of motion data

Description

technical field [0001] The invention relates to the capture of human motion data, in particular to a method for correcting noise and errors in the captured data of human motion. Background technique [0002] Human body motion capture technology is a technology that can directly capture human body movements, represent these movements with numbers, and use computers to process the movement data. It has important applications in many ways. In the field of computer animation, realistic human animation can be generated by capturing motion data; in the medical field, the force and moment on each joint of the human body can be calculated through motion capture data, and then the physiological condition of each joint can be analyzed. Similarly, in the field of sports, it is possible to analyze whether the athlete's movement is reasonable and how to improve the movement based on the calculated speed, acceleration and force. [0003] In human motion capture technology, the most wide...
