Abstract :
This paper focuses on the device tracking method for augmented reality. Based on stereo vision principle, marker location in the space is realized. The nonlinear model of camera, structure parameters of stereo vision system and marker´s sub-pixel tracking by gradient method which influence the system´s accuracy have been discussed. The problem of transformation matrix for rigid body structure in the space is resolved based on iterative closest point method. The research results can be used in the precise field for augmented reality.
