Geometric Correction For A Spherical Mirror Projection On A Nonplanar Surface, Methuen J. Bell-Isaac

Senior Projects Spring 2019

This paper discusses an approach for removing distortion from an image projected on a non-planar surface. With a single projector setup in a spherical mirror projection system, it becomes possible to preserve image features. The approach takes advantage of the configuration of the surface, specifically, the geodesic dome in this project. The configuration acts as a mold so that a warp mesh can be designed to match the surface configuration. Points in an image are then mapped to their corresponding point on the destination multi-planar surface represented by the mesh. The removal of distortion brings us a step closer to …
