Research Abstract

The main objective of this research is to obtain a target object shape from a set of snapshots simultaneously taken by handheld cameras with little effort. Based on a technique iterating volume intersection and projection, we proposed a method to extract silhouettes from photographs with minimal conflict and a method to optimize camera poses for volume intersection. And experimental results show that the camera placements are good when the shapes of silhouettes taken by the cameras are distinct each other and each shape is preferably complex.
