While traditional method of estimating joiont model using thinning process of 3D shapes cannot deal sphere joint model, this paper shows a method of estimating sphere joint model by comparing 3D shapes of many frames with using texture data and technique of Reeb Graph. 3D shapes is calculated by markerless motion capture with using viewing field intersection method. This method don't need previous knowledge of joint structure. In addition, this method can create joint model of the subject which don't have any joint, for example soft-bodied creatures.
