  • System and method for calibrating and adjusting a projected image of a projection apparatus
    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.

  • Calibration Method and Calibration System for Projection Apparatus
    Publication number: 20090067749
    Abstract: The invention relates to a calibration method and a calibration system for at least one projection apparatus for projecting images onto at least one projection area, where the geometric data from the 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 and the data from the calibration image are transmitted to the computer unit, 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 p
