Abstract
A system and method for calibrating location and orientation of a directional light source relative to a field of view of an optical device includes a directional light source that directs light to points on a virtual grid overlaying the field of view of the optical device. The optical device captures an image for each point on the virtual grid at which the directional light source directs light. A light dot is located in a plurality of captured images. The location and orientation of the directional light source are calibrated relative to the field of view of the optical device based on coordinates of each located light dot and on relative coordinates of the optical device.
