Methods for Geometrical Video Projector Calibration

J. Draréni, P.F. Sturm and S. Roy. In, Machine Vision and Applications Journal (MVA), January 2012, Volume 23, Issue 1, pp 79-89. In this paper we present two methods to geometrically calibrate a video projector using a markerless  planar surface. The first method assumes a partial knowledge on the camera parameters whereas the  second method […]

Projector Auto-Calibration

J. Draréni, S. Roy and P. Sturm In this paper we address the problem of geometric calibration of video projectors. Like in most previous methods we also use a camera that observes the projection on a planar surface. Contrary to those previous methods, we neither require the camera to be calibrated nor the presence of […]
