Abstract
A system and method of calibrating a light source relative to an optical device comprise virtually projecting by an image projector an image onto a three-dimensional surface of at least one object, the image comprising a virtual grid comprised of predefined points onto an area having the three-dimensional surface of at least one object, each predefined point of the virtual grid corresponding to one of a plurality of termination points of beams cast by the directional light source, at least one of the termination points of the beams are on a surface of the at least one object; simultaneously capturing by at least one optical device data for a plurality of points on the virtual grid by projecting the image into a field of view of the at least one optical device; and calibrating a location and orientation of the light source relative to the optical device using the captured data for the plurality of points.
