Markerless geometric registration of multiple projectors on extruded surfaces using an uncalibrated camera

摘要

A method for registering multiple projectors on a vertically extruded three dimensional display surface with a known aspect ratio includes recovering both the camera parameters and the three dimensional shape of the surface from a single image of the display surface from an uncalibrated camera, capturing images from the projectors to relate the projector coordinates with the display surface points, and segmenting parts of the image for each projector to register the projectors to create a seamlessly wall-paper projection on the display surface using a representation between the projector coordinates with display surface points using a rational Bezier patch. A method for performing a deterministic geometric auto-calibration to find intrinsic and extrinsic parameters of each projector is included.
