I designed a robust, fast, low-cost method to achieving high-quality automatic calibrations between target surfaces and projectors. Using RGB sensors, a microcontroller and off-the-shelf projector as hardware, I encode the sensor data into 2.5d location coordinates and implement homography to warp the image. This system allows adjustment of the image to fit the target surface in the 3d space even when it changes position and orientation with respect to the projector.
