Abstract: Techniques are disclosed for tracking the position of moving parts and assemblies using 3D laser projection, and projecting templates and other information onto the parts and assemblies based on position. The projected template may then be used, for example, to assist in fabrication of an assembly by indicating where to put a next component or layer, or to assist in post-fabrication inspection of an assembly by indicating where the various components or layers should have been placed. Reference targets can be used as fiducial points for aligning a laser projector with the work piece in question. When the work piece rotates or is otherwise moved to a next manufacturing or inspection position, the relative position of the laser projector and the work piece is updated by bucking-in to the reference targets. The laser projector can then project patterns or other information onto the work piece at the appropriate locations.
