The traditional approaches are suffering from the problems of expensive computation, low efficiency, and lack of vitality. A new approach called tight-clothing and camera calibration based human animation is proposed in this paper. After videotaping the model dressed in tight-clothing, people can track human joint in image sequence automatically, then construct corresponding three-dimension human motion skeleton sequence under the perspective projection, finally the mapping of human motion onto the motion of other roles is completed by making BVH(biovision hierarchy)file.This approach has the characteristics of the rich source materal,efficient production,low cost and realistic animation result.It is possible to release the animators from the redious work.Also such technique can step into families for its low cost.
