Abstract: A system and method for geometric warping correction in projection mapping is provided. A lower resolution mesh is applied to A mesh model, at least in a region of the mesh model misaligned with a corresponding region of a real-world object. One or more points of the lower resolution mesh are moved. In response, one or more corresponding points of the mesh model are moved to increase alignment between the region of the mesh model and the corresponding region of the real-world object. An updated mesh model is stored in a memory. And one or more projectors are controlled to projection map images corresponding to the updated mesh model onto the real-world object.

Abstract: A system and method for automatic alignment and projection mapping are provided. A projector and at least two cameras are mounted with fields of view that overlap a projection area on a three-dimensional environment.

Abstract: A system and method for digital black level blending is provided.

Abstract: A system and method for digital black level blending is provided. The system comprises: projectors located to project respective images, onto a screen, that overlap in one or more overlap regions; at least one camera; and a computing device configured to, for each given projector: determine, using the at least one camera, respective correspondences between projected points of a given image, projected onto the screen by the given projector, and respective points of respective image modulators of other projectors of the projectors, the respective correspondences representing the respective points of the respective image modulators of the other projectors that correspond to overlap regions; determine respective brightness of the overlap regions; and, control pixels of an image modulator of the projector, and each of the respective image modulators, at least adjacent edge pixels corresponding to edges of overlap regions, to increase brightness in corresponding image regions using the respective brightness.

Abstract: A method, system, and a computer readable medium for screen correction is provided. The system includes a memory storage unit for storing model content, a screen having screen parameters, an input device for receiving the screen parameters, a correction engine, and a projector. The method involves storing model content on a memory storage unit, receiving screen parameters, generating screen content, and projection at least a portion of the screen content onto the screen. The computer readable medium encoded with codes for directing a processor to carry out the method.

Abstract: A method, system and apparatus for determining locations in a projected image are provided. The apparatus comprises a light sensor; a body comprising the light sensor, the body enabled to position the light sensor proximal to a screen to detect light from a projector; a communication interface for communicating with a projector system comprising at least the projector; and, a processor enabled to transmit a request to the projector system to project a structured light pattern using the projector; and when at least one pixel in the structured light pattern projected by the projector is detected at the light sensor, transmit a detection indication to the projector system to communicate detection of the at least one pixel.
