The invention discloses a calculation method capable of correcting multiple initial attitude angles with arbitrary deviations to a unified coordinate system, which is used in an attitude measurement capture analysis system. The attitude measurement capture analysis system has a first coordinate system, and the attitude measurement capture analysis system has a first coordinate system. The analysis system includes a predetermined sensor, the predetermined sensor has a second coordinate system, and the calculation method includes: adjusting the predetermined sensor to a first state, and obtaining the second coordinate system of the predetermined sensor in the first state the first data in the predetermined sensor; adjust the predetermined sensor to the second state, and acquire the second data in the second coordinate system of the predetermined sensor in the second state; adjust the predetermined sensor to the first a state; adjust the predetermined sensor to a third state, and obtain third data in the second coordinate system of the predetermined sensor in the third state; and calculate the predetermined sensor relative to the first coordinate Calibration quaternion for the system.
Description
technical field [0001] The invention relates to a calculation method and an attitude measurement capture analysis system, in particular to a calculation method and an attitude measurement capture analysis system capable of quickly obtaining the positions and attitudes of human joints. Background technique [0002] At present, attitude sensors, especially MEMS attitude sensors, have been well applied in the field of acquiring human joint attitude. Such attitude sensors include accelerometers, gyroscopes, and magnetic sensors, which, combined with specific algorithms, can be used to measure spatial attitude. Install the posture sensor to the human skeleton, and obtain the posture angle to obtain the posture of the human joints. However, due to the uncertainty of the installation position of the attitude sensor and the randomness of human joint movement, it is often necessary to reset and calibrate after each installation of the attitude sensor, which is not only time-consumin...
