Abstract
A system includes a camera, a visual target including a GPS receiver, and a processor. The camera images the visual target at a plurality of locations to obtain a plurality of images. The processor receives GPS coordinates for each respective location. Also, the processor determines a 3D location of the visual target in a camera reference frame for each of the images. The processor derives a plurality of estimated GPS camera locations for each of the plurality of images and mitigates an error associated with each of the derived estimated GPS camera locations to derive an average GPS camera location. This location is used to determine and store a transformation usable to describe objects viewed by the camera in the camera reference frame in terms of the GPS reference frame.
