SYSTEM AND METHOD FOR CALIBRATING A DISPLAY SYSTEM USING A SHORT THROW CAMERA

摘要

This invention overcomes disadvantages of the prior art by providing a system and method that allows for the calibration of a display system using one or more cameras whose lenses are not modeled, or are modeled with limited accuracy, and are potentially incapable of imaging the entire projector system. The illustrative system and method generally relies on well-established models of the projectors, rather than well-established models of the cameras. Illustratively, the cameras serve mainly to map the projectors into one coordinate system, where the overlap between the projectors can be established very precisely using a camera, even if the model of the camera lens properties is not known, or known only minimally.
