An efficient projector calibration method for projecting virtual reality on cylindrical surfaces

In this paper, we propose a fast and easy-to-use projector calibration method needing a minimum set of input data, thus reducing the calibration time. The method is based on the Direct Linear Transformation (DLT) mathematical model, which makes it simple and fully automatic. We show the application of this method on cylindrical surfaces, as well as some real application examples. The results show that with the minimum configuration of 6 control points (CPs), the standard deviation in the projector positioning yielded by the calibration process is less than one per cent of the position values.
