  • Patent number: 10276075
    Abstract: A device, system and method for automatic calibration of image devices is provided. Triplets of at least three image devices, including a projector, are in non-collinear arrangements, and pairs of the image devices have overlapping fields of view on a physical object. Pixel correspondences between the pairs are used to determine relative vectors between the image devices. Relative locations between each of the image devices are determined based on the relative vectors with a relative distance between one pair of the image devices is to an arbitrary distance, the relative locations being further relative to a cloud-of-points representing the object. A model of the object and the cloud-of-points are aligned to transform the relative locations of each of the image devices to locations relative to the model. The projector is controlled to project onto the object based at least on the locations relative to the model.

  • Publication number: 20180139423
    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.
