Abstract: This paper presents a system for measuring and analyzing 6D motions of model with non-touched style.There are
three modules including video capture，image processing and user interface.Video cameras are used to capture the motion of
the model at each moment，and improved self-calibration technology，feature point extraction technology in 3D vision and six dimensional calculation methods are used to get the motion in six degrees.User interface makes it easy to get the information
at any time and any angle of view.Experiment in real environment has proved that the system is simple to use and
with high efficiency.It can work in complicated environment and long distance.

Key words: six degrees of freedom, self-calibration, motion measuring equipment, non-touched style
