MULTI-EPIPOLAR LINES MATCHING-BASED RAY-SPACE INTERPOLATION FOR FREE VIEWPOINT VIDEO SYSTEM

Ray-space based arbitrary viewpoint rendering without complex object segmentation or model construction is the main technology to realize Free Viewpoint Video （FVV） system for complex scenes. Ray-space interpolation and compression are two key techniques for the solution. In this paper, correlation among multiple epipolar lines in ray-space data is analyzed, and a new method of ray-space interpolation with multi-epipolar lines matching is proposed. Comparing with the pixel-based matching interpolation method and the block-based matching interpolation method, the proposed method can achieve higher Peak Signal to Noise Ratio （PSNR） in interpolating ray- space data and rendering arbitrary viewpoint images.
