On the basis of the study of cadavers with the technigue of CT and DIP in this project, 50 young females were undergone investigations through scanning, image analysis, examination and statistics. The inertial data of the Chinese female young bodies including the length, volume, mass and density of the segments of the body, etc. were obtained. The mass distribution of the Chinese female young bodies was determined. A series of reliable data is then provided for establishing the model with inertial parameters of the Chinese human body.
