Aspects of the present invention include systems and methods for recalibrating projector-camera systems. In embodiments, systems and methods are able to recalibrate automatically the projector with arbitrary intrinsic and pose, as well as render for arbitrarily desired viewing point. In contrast to previous methods, the methods disclosed herein use the observing camera and the projector to form a stereo pair. Structured light is used to perform pixel-level fine reconstruction of the display surface. In embodiments, the geometric warping is implemented as a direct texture mapping problem. As a result, re-calibration of the projector movement is performed by simply computing the new projection matrix and setting it as a camera matrix. For re-calibrating the new view point, the texture mapping is modified according to the new camera matrix. |
