Auto-Calibration of Multi-Projector Display Walls
Andrew Raij, Marc Pollefeys · 2004
By treating projectors as pin-hole cameras, we show it is possible to calibrate the projectors of a casually-aligned, multi-projector display wall using the principles of planar auto-calibration. We also use a pose estimation technique for planar scenes to reconstruct the relative pose of the camera, the projectors and the display plane they project on. Together with assumptions about the pose of a camera observing the display plane, we use the reconstruction to automatically compute the projector-display homographies needed to render properly scaled and oriented imagery on the display wall.
