A Flexible Projector-Camera System for Multi-Planar Displays

We present a novel multi-planar display system based on an uncalibrated projector-camera pair. Our system exploits the juxtaposition of planar surfaces in a room to create ad-hoc visualization and display capabilities. In an office setting, for example, a desk pushed against a wall provides two perpendicular surfaces that can simultaneously display elevation and plan views of an architectural model. In contrast to previous room-level projector-camera systems, our method is based on a flexible calibration procedure that requires a minimum amount of information for the geometry of the multi-planar surface scenario. A number of display configurations can be created on any available planar surfaces using a single commodity projector and camera. The key to our calibration approach is an efficient technique for simultaneously localizing multiple planes and a robust planar metric rectification method which can tolerate a restricted camera field-of-view and requires no special calibration obj...
