Abstract
A method and apparatus for tracking a location of an object or target in a 3D space. At least one target including unique sub-targets is attached to a vision object in the 3D space. A camera disposed in a 3D space, and coupled to a computing device captures a 2D image of a target. The camera computing device identifies the sub-targets of the target and transfers the sub-target data to a computing device associated with the camera which accesses a data base of target data to identify target an, using sub-target separation distances in the database to determine 3D location and orientation of the target. Another computing device transforms the 3D locations of the detected target in the camera coordinate system into a single 3D coordinate system for the 3D space. The 3D location of targets detected by multiple cameras of different computing devices maybe daisy chained together to convert the target location in the 3D coordinate systems of each computing device into a single 3D coordinate system.
