抄録

We are researching a modeling algorithm for the moving human body to generate a fine, dynamic, 3D object. In this paper, we propose a modeling method from multiple viewpoints. This modeling method uses an approximate shape, obtained by the volume intersection method with restrictive conditions set by the stereo matching method.<BR>In addition, in order to map the image texture on the surface of the dynamic 3D objects, we propose a vertex texture mapping method based on ray-casting. Our modeling experiments were performed using 19 Firewire cameras. <BR>We were able to confirm that the proposed methods are effective for generating fine, dynamic, 3D objects. The dynamic 3D object generated can be displayed as an “animation” by using a VRML browser.
