| Abstract(in English) | In this paper, we propose a new approach for reconstructing existing architectures from some photographs for the landscape simulation. Stereo vision techniques are employed. For accurate shape reconstruction, two cameras must be located far each other. To realize free camera allocation, we calibrate the camera position and direction from three ridge-lines crossing at right angles in each photograph and alength of them. By two photographs calibrated by the same ridge-lines, we reconstruct 3D shapes of architectures by stereo vision. And then correcting process is executed with parallelism and perpendicularity of edges. Finally, we get textures of the reconstructed architecture from its photographs. Experimental results confirmed that our approach can reconstruct architectures within an error of 1.0% with enough length of base line. In case of low precision, we obtain good architecture by shape correction. |
