3D shape recovery with no explicit video projector calibration

3D shape reconstruction is a common task in many areas of interests. Yet, very often it involves sophisticated hardware and software. This paper represents cheap and simple system, both in hardware and software sense, for 3D subjects shape reconstruction. It consists of video camera(s) and video projector and is based on well known principle of structured light. A major contribution of the paper is method, which avoids explicit traditional video projector calibration. A system accuracy results are shown along with experimental results of reconstruction for human face and toy mushroom. The system can be easily implemented and adjusted for all kinds of other applications
