DEVICE AND METHOD FOR FINDING 3D SHAPE OF OBJECT |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a device and a method for finding a 3D shape of an object by generating a viewed volume cross region based on a single image obtained from the object in a scene. <P>SOLUTION: The object 101 is illuminated and a plurality of silhouettes are projected onto a diffusion screen coplanor and in close proximity to a mask. A single image obtained from a diffusion screen like this is divided into a plurality of sub-views according to the silhouettes. Then, the visual hull of the object is constructed according to isosurfaces of a binarized image to approximate the 3D shape 103 of the object. <P>COPYRIGHT: (C)2010,JPO&INPIT |
