Abstract

In this paper, we present a fully automatic method for the geometric calibration of a video projector. The approach is based on the Heikkila’s camera calibration algorithm. It combines Gray coded structured light patterns projection and a RGBD camera. Any projection surface can be used. Intrinsic and extrinsic parameters are computed without a scale factor uncertainty and any prior knowledge about the projector and the projection surface. While the structured light provides pixel to pixel correspondences between the projector and the camera, the depth map provides the 3D coordinates of the projected points. Couples of pixel coordinates and their corresponding 3D coordinates are established and used as input for the Heikkila’s algorithm. The projector calibration is used as a basis to augment the scene with information from the RGBD camera in real-time.
