            Abstract : 
A new positioning method based on image recognition technologies is presented to identify the six DOF of a shooting device, on which a light beam emission device is fixed, relative to the projection plane in a three-dimensional space. The intersection points emitted by the light beam emission device on the plane are picked up by a calibrated camera and the positions of the projecting points are computed. With the data acquired above, the position and attitude of the shooting device are acquired. Experiments of such a system have been implemented and the factors affecting the positioning accuracy are analyzed.
