Abstract: Detecting and positioning analysis methods for human body functional joint rotation center. The detection method for human body functional joint rotation center comprises the following steps: 11, abstracting a human body functional joint rotation center FCR into the sphere center of a flexible sphere in a section of continuous movement; and 12, at any moment in the test process, determining the location coordinates of the sphere center (namely FCR) at the moment according to the location coordinates of M1, M2 and M3, and further obtaining the motion trajectory of the FCR in the continuous motion. The positioning analysis method conducts positioning analysis on the joint location on the basis of morphological parameters collected by three-dimensional scanning. Based on the idea of a flexible sphere, the detecting method is simple and convenient in operation within a certain error range, and is excellent in continuity of a joint trajectory. According to the positioning analysis method, the location of the rotation center of the joint of the whole body can be obtained only by performing transient three-dimensional scanning on the human body, such that positioning analysis of the joint location gets rid of complex kinematics analysis, and the positioning is faster.
