Abstract
A method for verifying performance of a light projector includes establishing a reference artifact that include reflective makers and an interior edge line, determining with a laser-tracker-based three-dimensional (3D) measuring system 3D coordinates of the reflective targets and the interior edge line, determining with the light projector angles to the reflective markers with the light projector, and projecting with the light projector a pattern of light onto the interior edge line.
