We have created a suite of automated tools to calibrate and configure a projection virtual reality system. Test subjects (rats) explore an interactive computer-graphics environment presented on a large curved screen using multiple projectors. The locations and characteristics of the projectors can vary and the shape of the screen may be complex. We reconstruct the 3D geometry of the screen and the location of each projector using shape-from-motion and structured-light multi-camera computer vision techniques. We determine which projected pixel corresponds to a given view direction for the rat and store this information in a warp map for each projector. The projector uses that view direction to look up pixel colors in an animated cubemap. The result is a pre-distorted output image which appears undistorted to the rat's viewpoint when displayed to the screen. |
