Abstract

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.
