Outline of Final Research Achievements

This research is aimed at estimating the full 3D shape of objects using a single camera and multiple mirrors. Given kaleidoscopic images of an object, our method can estimate the mirror poses and the object 3D geometry simultaneously without using any other reference objects in the scene. We proposed a new linear algorithm for such mirror pose and 3D geometry estimation, and designed a mirror arrangement that is optimized in terms of coverage and triangulation accuracy for full 3D capture. Also we developed a real system with a kaleidoscopic mirrors with a projector-camera system to demonstrate the performance of our method.
