Motion tracking system based on stealthy code road sign

The utility model discloses a motion tracking system based on stealthy code road sign. It contains the vision positioning module and arranges the stealthy code road sign in the environment. The vision positioning module includes camera module and image processing module. Camera module wherein for catch the stealthy code road sign in the environment, image processing module is used for the image decode that catches the camera module, and obtains orientation module 6 -degree of freedom's in the space position and gesture. Sign indicating number on the stealthy code road sign of deployment in the environment adopts to return reflective material, can postback light department with light reflection. Its stealthy function mainly through the code road sign rather than of the adhering to the object the colour the same or realize recently mutually. The utility model provides a location is accurate, the algorithm complexity low, the reliability is high, need not to mark, arranges the motion tracking system who hangs do
