Claim 0:
1. A multi-view camera-based iterative calibration method for generation of a 3D volumetric model, the multi-view camera-based iterative calibration method comprising:
(a) receiving one or more multi-view color-depth images;
(b) performing a point cloud of each viewpoint by converting each multi-view color-depth image into the point cloud;
(c) performing top-bottom calibration by optimizing a transformation parameter by calibrating top-bottom point clouds which are point clouds of viewpoints adjacent in a vertical direction, and matching the top-bottom point clouds;
(d) performing round calibration by optimizing the transformation parameter by calibrating top-bottom matched point clouds of viewpoints adjacent in a horizontal direction; and
(e) performing viewpoint calibration by generating a point cloud of a virtual viewpoint by combining some of the top-bottom point clouds of at least two viewpoints, and optimizing the transformation parameter by calibrating a viewpoint adjacent to the virtual viewpoint.
