抄録

This paper proposes a practical fully-automatic method of 3D modeling for VR-systems by utilizing moving shots of a stereo camera. VR-modeling based on measured data is generally composed of the following process: 3D measurement with high-precision laser range sensors, texture acquisition with high-definition digital cameras, and alignment between 3D model and texture. However, this is often the case laser range sensors are difficult to handle with and the alignment process is mostly dependent on manual work by trained operators. To overcome the above problems, we give an eye to the stereo camera, which is handy to use and can simultaneously acquire the 3D shape and texture, though its accuracy is not as good as that of laser sensors. And utilizing the feature tracking technique on the image sequence, we can automatically align all the partial models estimated from stereo pairs and observe the whole model immediately after the shooting. Our system enables automatic generation of VR-model by simply moving a stereo camera around a target object and taking a series of stereo pair images. Finally, we show several kinds of VR-model generated by our system and confirm that our system is effective for a specific application, such as a VR-contents presented in the theater.
