Abstract:
A method adjusts a pose of a projector with respect to a display surface. A homography HD,P is determined between a display surface and a projector. The homography HD,P is decomposed into rotation and translation parameters expressing a pose MP of the projector. An ideal pose M0 of the projector corresponding to an ideal homography H0 is determined. A pose adjustment MA is determined according to MA=M0(MP)-1. The pose adjustment MA is decomposed into rotation and translation adjustment parameters.
