Projection Center Calibration for a Co-located Projector Camera System
AbstractA co-located projector camera system where the projector and camera are positioned in the same optical position by a plate beam splitter enables various spatial augmented reality applications for dynamic three dimensional scenes. The extremely precise alignment of the projection centers of the camera and projector is necessary for these applications. However, the conventional calibration procedure for a camera and projector cannot achieve high accuracy because an iterative verification process for the alignment is not included. This paper proposes a novel interactive alignment approach that displays a capture of the projected grid pattern on the calibration screen. Additionally, a misalignment display technique that employs projector camera feedback is proposed for fine adjustment.
