Method and Apparatus for Determining 3D Shapes of Objects

摘要

An apparatus and method determine a 3D shape of an object in a scene. The object is illuminated to cast multiple silhouettes on a diffusing screen coplanar and in close proximity to a mask. A single image acquired of the diffusing screen is partitioned into subview according to the silhouettes. A visual hull of the object is then constructed according to isosurfaces of the binary images to approximate the 3D shape of the object.
