ProCam Calibration using Single Pose of 2D Planar Target
This thesis presents a simple and user friendly method for calibrating a procam system from a single pose of a 2D planar target. The camera intrinsic parameters, projector intrinsic parameters, procam system's extrinsic parameters and the distortion coe cients of the camera are returned using this method. Two sets of experiments were conducted: simulation experiments and real data experiments. The purpose of the simulation experiments were to test which poses of a camera and projector relative to a chessboard produce accurate calibration parameters. Several poses of a chessboard were imaged and used to calibrate a real procam system using the technique presented in this thesis and a Zhang-based method was used as the ground truth. The results of the real data experiments are congruent with the simulation experiments; accurate camera intrinsic parameters are returned when absolute sum of the X-axis and Y-axis rotation of the chessboard relative to the camera is greater than 20 degrees and accurate projector intrinsic parameters when the absolute value of the Y-axis rotation of the chessboard relative to the projector is greater than 10 degrees. When the conditions for valid camera and projector intrinsic parameters are met then accurate extrinsic parameters are returned as well.
