METHOD FOR THE POSITIONALLY ACCURATE PROJECTION OF A MARK ONTO AN OBJECT, AND PROJECTION APPARATUS

摘要

Disclosed is a projection apparatus (1) in which a capturing and/or measuring device (2) is used for measuring a three-dimensional position and/or orientation of an object (3), a projection pose of a projection means (4) is calculated from the result of said measurement, and the projection means (4) is oriented in such a way that a mark (20) predefined in a 2D or 3D model (13) of the object (3) is projected in a positionally accurate manner onto the object (3).
