ABSTRACT:
A method adjusts a pose of a projector with respect to a display surface. A homography HD,Pis determined between a display surface and a projector. The homography HD,Pis decomposed into rotation and translation parameters expressing a pose MPof the projector. An ideal pose M0of the projector corresponding to an ideal homography H0is determined. A pose adjustment MAis determined according to MA=M0(MP)−1. The pose adjustment MAis decomposed into rotation and translation adjustment parameters. Then, the projector is adjusted mechanically to the ideal pose M0according to the rotation and translation adjustment parameters.
