ABSTRACT:
A projector system having a process utilizing three-dimensional data, thereby allowing the system to account for rotational and translational differences between the projector and the object upon which the laser light is directed. Reference targets located on the object are in a known relationship to the projected three dimensional data. The reference targets are retro-reflective, such that light steered by the projector, when impinging on the reference targets, will return to the projector for detection and determination of the relative translation and orientation between projector and object. The three-dimensional data is then converted to a format suitable for projection using said translation and orientation information.
