A system and method for registering images captured by a camera of heliostats in a heliostat field for use in tracking control of the heliostats is disclosed. The method includes calculating a geographical location of a reflection of the sun on a reflective dome surface of fiducial markers positioned relative to the heliostat field that are in a field of view of the camera, the geographical location calculated based on a location of the sun at a time corresponding to a time-stamp of the captured image, a geographical location and a radius of the reflective dome of the fiducial markers, and a geographical location of the viewing camera. A correct mapping of the fiducial markers in the captured image is identified. Optionally, an affine transform is applied to the captured image via rotation and translation so that pixels in the transformed image for the fiducial markers map to geographical coordinates of the fiducial markers.
