On Degeneracy of Optical See-Through HMD Calibration
光学透视式头盔显示器标定的退化影响

For a successful augmented reality application,precise projection information of the viewing device is required,which has to calibrate the optical see-through head-mounted display in use.Based on our system,this paper selects the calibration algorithm of the virtual camera which models the combination of HMD and user's eye.According to the influence of degenerate point configurations of projection matrix,the number of calibration correspondences and the track of user's head are improved.Experiments reveal that the calibration effect is meliorated distinctly and the success rate is increased greatly.
