NOVEL PROJECTOR CALIBRATION APPROACHES OF MULTI-RESOLUTION DISPLAY
Po Hsun Chiu, Shih Yao Lin, Li Wei Chan, Neng Hao Yu, Yi Ping HungAbstract
This paper proposes convenient and useful approaches to automatically calibrate the projectors of a multi-resolution display. The proposed approaches estimate both the keystone effect and misalignment of the projections with an assistance of a color camera. Structured light patterns are employed to construct the geometric relationship between projectors and the projection surface, and then pre-warp the images so that they appear undistorted as a result. Experimental results demonstrate that the proposed approaches successfully reduce the human-effort and lower the calibration time of multi-resolution display calibration task.
