1. A method for calibrating cameras in a rig, the method comprising:
projecting light patterns onto surfaces of objects in a capture volume;
capturing image data of the light patterns projected onto the surfaces of the objects using the cameras; and
processing the captured image data to estimate a calibration data of the cameras; and
measuring distortions in the light patterns using the estimated calibration data of the cameras as camera angles relative to changes on the surfaces of the objects,
wherein the measured distortions in the light patterns of the captured image data identifies source information about which camera of the cameras is providing the image data.
