Method for projecting image data on projection surface, involves projecting image data on projection surface by laser beam, where laser beam is emitted by projector

摘要

The method involves projecting the image data on the projection surface (1) by a laser beam. The laser beam is emitted by a projector (2). The position information to the relative position of the projector is detected by an optical detector, which detects reflections of the laser beam from three measuring points (6,7,8,9) of the projection surface. The measuring points are not positioned in straight lines. An independent claim is included for a device for projecting image data on a projection surface.
