In this paper, we propose geometry based image-based rendering method for sparse multicamera system using multiple local ray-space representation and 3-D model generation. In this system, the quality of walk-through view experience is impaired by inaccurate camera parameters and 3-D model. In order to eliminate these affects, we enhance the reconstructed local ray-spaces using stereo matching approach. Hence, free viewpoint rendering quality is improved significantly for walk-through image synthesis. Experimental results for several multiview sequences verify the effectiveness of our approach.
