Camera-assisted automatic screen fitting

A method comprising:

• image capturing one or more projected solid field patterns as one or more imaged solid patterns via one or more cameras;
• for one or more camera perspective planes of the one or more cameras, determining first corner coordinates of user-defined sub-screens, based on differences in pixel values of the one or more imaged solid patterns;
• determining homography matrices associated with the one or more camera perspective planes and associated with one or more projector perspective planes of one or more projectors;
• for the one or more projector perspective planes, transforming the first corner coordinates to second corner coordinates of the sub-screens, based on the homography matrices;
• and
• projecting images based on the second corner coordinates.

Apparatus comprising:

• a projector to project solid field patterns onto a screen, wherein the screen includes user-defined sub-screens;
• a camera to image capture the projected solid field patterns as imaged solid patterns;
• and
• a processor to:
• for a camera perspective plane of the camera, determine first corner coordinates of the sub-screens, based on differences in pixel values of the imaged solid patterns;
• determine a homography matrix associated with the camera perspective plane and associated with a projector perspective plane of the projector;
• and, for the projector perspective plane, transform the first corner coordinates to second corner coordinates of the sub-screens, based on the homography matrix.
