Abstract
Two projected images from two projector-camera systems, each defined by characteristics c1=T1p1 and c2=T2p2, respectively, are used to create mosaic composite of a desired image c. Formulas p1=T1−1 (c−T2p2) and p2=T2−1(c−T1p1) are iteratively repeated with p2 initially set to zero until p1 converges to a first mosaic image and p2 converges to a second mosaic image.
Claims11
A method for mosaicing a first projected image from a first projector-camera system and a second image projected image from a second projector-camera system, comprising:
- (a) establishing a first light transport matrix T1 that relates a first camera image c1 of said first projector-camera system to a first projector image p1 of said first projector-camera system according to relation c1=T1p1;
- (b) establishing a second light transport matrix T2 that relates a second camera image c2 of said second projector-camera system to a second projector image p2 of said second projector-camera system according to relation c2=T2p2;
- (c) defining a desired composite image “c”;
- (d) setting P2 equal to zero, solving for p1 in formula p1=T1−1 (c−T2p2);
- (e) using the current solved value for p1, solving for p2 in formula p2=T2−1 (c−T1p1);
- (f) using the current solved value for p2, solving for p1 in formula p1=T1−1 (c−T2p2);
- (g) repeating steps (e) and (f) in sequence until p1 converges to a first mosaicing image and p2 converges to a second mosaicing image.
