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.

System and method of calibrating a directional light source relative to a camera's field of view

An apparatus comprises a mount body by which the apparatus is secured to a structure. A camera assembly includes an image sensor adapted to capture images within its field of view. A lighting assembly houses one or more light sources including a directional light source. A control-board assembly, fixed to the mount body, houses control boards including one or more processors configured to acquire information about an object, to associate a location within the field of view of the image sensor with the object, to point light emitted by the directional light source at the location associated with the object by rotating the lighting assembly and turning the laser assembly, and, based on an image acquired from the camera assembly, to detect change within the field of view of the image sensor corresponding to placement or removal of the object.

Computer-vision-based object tracking and guidance module

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.
