  • Patent number: 9237320
    Abstract: The invention relates to a method and an apparatus for generating a calibrated projection, wherein the method for example includes providing a projection surface (1) for the projection of at least one image (2), wherein the projection surface (1) includes a calibrating structure (5) following its spatial extension, which has a first side (51) and a second side (52), which extends parallel to the first side (51), and a constant height as measured in direction of the first or the second side (51, 52), generating an image (5?) of the calibrating structure (5) in an image plane by means of a camera (4), reconstructing the spatial extension of the projection surface (1) in the region of the calibrating structure (5), and generating a projection calibrated with respect to the calibrating structure by using the spatial extension of the projection surface reconstructed according to the providing projection surface step.

  • Patent number: 8311366
    Abstract: The invention relates to a calibration method and system for at least one projection apparatus, where the geometric data from at least one projection area has been or are stored in advance in a computer unit, wherein a) the at least one projection apparatus projects previously known calibration patterns onto at least one portion of the projection area, with the calibration patterns having at least one overlap region among one another, b) the calibration patterns are recorded by at least one camera apparatus as a calibration image, where c) the computer unit is used to automatically ascertain the difference between the recorded real calibration image and an ideal depiction result from the previously known calibration pattern on the projection area as a reference pattern, and where subsequently the difference between the real calibration image and the reference pattern is used to ascertain a correction transform.

  • Patent number: 7215362
    Abstract: The method for automatically calibrating a multi-projector system with at least two projectors, a digital camera and a control unit for controlling the projectors and the camera is performed according to the following steps: production, capture and image-filtering of strip patterns, finding the largest projection surface possible, and calculation of warp fields and image-warping.
