Simultaneous Geometric and Radiometric Calibration of a Projector-Camera Pair

We present a novel method that allows for simultane- ous geometric and radiometric calibration of a projector- camera pair. It is simple and does not require specialized hardware. We prewarp and align a specially designed pro- jection pattern onto a printed pattern of different colorimet- ric properties. After capturing the patterns in several ori- entations, we perform geometric calibration by estimating the corner locations of the two patterns in different color channels. We perform radiometric calibration of the projec- tor by using the information contained inside the projected squares. We show that our method performs on par with current approaches that all require separate geometric and radiometric calibration, while being more efficient and user friendly.
