  A novel user friendly method is proposed for calibrating a procam system from
a single pose of a planar chessboard target. The user simply needs to orient
the chessboard in a single appropriate pose. A sequence of Gray Code patterns
are projected onto the chessboard, which allows correspondences between the
camera, projector and the chessboard to be automatically extracted. These
correspondences are fed as input to a nonlinear optimization method that models
the projector of the principle points onto the chessboard, and accurately
calculates the intrinsic and extrinsic parameters of both the camera and the
projector, as well as the camera's distortion coefficients. The method is
experimentally validated on the procam system, which is shown to be comparable
in accuracy with existing multi-pose approaches. The impact of the orientation
of the chessboard with respect to the procam imaging places is also explored
through extensive simulation.
