Abstract
A method for compensating for cross-talk in a 3-D projector-camera system having a controller including a processor and system memory and at least two channels, includes the steps of calibrating the projector-camera system, computing cross-talk factors applicable to the projector-camera system, and correcting new image data for cross-talk based upon the computed cross-talk factors. The system is calibrated by sequentially projecting and capturing, with a camera, a calibration image for each channel, to capture cross-talk between the channels. The controller can compute the cross-talk factors based upon the captured calibration images.
