3D Photography

Jean Ponce


Abstract

This talk addresses the problem of automatically acquiring three-dimensional object and scene models from multiple pictures, a process known as 3D photography. I will introduce a relative of Chasles' absolute conic, the absolute quadratic complex, and discuss its applications to the calibration of cameras with rectangular or square pixels without the use of calibration charts. I will also present a novel algorithm that uses the geometric and photometric constraints associated with multiple calibrated photographs to construct high-quality solid models of complex 3D objects in the form of carved visual hulls. If time permits, I will also briefly discuss our most recent results on category-level object recognition. Joint work with Yasutaka Furukawa, Svetlana Lazebnik, Kenton McHenry, Theo Papadopoulo, Cordelia Schmid, Monique Teillaud and Bill Triggs.
