Projector-camera systems are commonly used for projector calibration. Conventional methods usually use stationary cameras and temporal coded structured light (SL). In this paper, we propose a projector calibration method using a mobile camera and spatial coded SL. Our method allows the users to use a handheld camera to carry out projector calibration and therefore reduce the effort and time required for camera setup. Although the decoding of temporal coded SL can be error-prone in a real-world situation, our method can achieve robust calibration results by taking advantage of the multi-view observations of the projection thanks to the mobility of the camera. Experiments show that the result of our method is comparable with that of a checkerboard-based approach.
