A positioning method of functional rotation center of shoulder based on rigid upper arm model includes: step: abstracting a human upper arm into a cylinder with FRCS as a center of top surface; step: determining a reference axis vector of the cylinder; step: determining an axis vector of the cylinder and a displacement from the reference axis vector to the axis vector; step: correcting a central axis direction of the cylinder; step: determining a height compensation of the cylinder, and positioning the FRCS. The method has higher accuracy for the positioning result of FRCS, the positioning result of FRCS has better stability relative to the upper arm and trunk, and can be used to establish a more accurate human digital dynamic model and predict more accurate human posture.

A detecting method and a positioning analysis method of human functional joint rotation center are provided. The detecting method of human functional joint rotation center includes: step: in a continuous motion, a human functional joint rotation center FCR is abstracted as a center of a flexible ball; step: at any moment during a test, position coordinates of the center of the ball (i.e. FCR) at the moment are determined according to position coordinates of M1, M2 and M3, and then the motion trajectory of the FCR is obtained in the continuous motion; the positioning analysis method performs positioning analysis of joint positions based on morphological parameters collected by 3D scanning. The detecting method is based on an idea of flexible ball, its operation is simple within a certain error range, and the method performs very well in the continuity of trajectory of joint.
