APPARATUS AND METHOD FOR ESTIMATING JOINT STRUCTURE OF HUMAN BODY
First Claim
1. An apparatus for estimating a joint structure of a human body, comprisinga multi-view image acquisition unit for receiving multi-view images acquired by capturing a human body;
- a human body foreground separation unit for extracting a foreground region corresponding to the human body from the acquired multi-view images;
a human body shape restoration unit for restoring voxels indicating geometric space occupation information of the human body using the foreground region corresponding to the human body, thus generating voxel-based three-dimensional (3D) shape information of the human body;
a skeleton information extraction unit for generating 3D skeleton information from the generated voxel-based 3D shape information of the human body; and
a skeletal structure estimation unit for estimating positions of respective joints from a skeletal structure of the human body using both the generated 3D skeleton information and anthropometric information.

Abstract
Disclosed herein is an apparatus and method for estimating the joint structure of a human body. The apparatus includes a multi-view image acquisition unit for receiving multi-view images acquired by capturing a human body. A human body foreground separation unit extracts a foreground region corresponding to the human body from the acquired multi-view images. A human body shape restoration unit restores voxels indicating geometric space occupation information of the human body using the foreground region corresponding to the human body, thus generating voxel-based three-dimensional (3D) shape information of the human body. A skeleton information extraction unit generates 3D skeleton information from the generated voxel-based 3D shape information of the human body. A skeletal structure estimation unit estimates positions of respective joints from a skeletal structure of the human body using both the generated 3D skeleton information and anthropometric information.
