Generalizable Novel-View Synthesis using a Stereo Camera

In this paper we propose the first generalizable view synthesis approach that specifically targets multi-view stereo-camera images. Since recent stereo matching has demonstrated accurate geometry prediction we introduce stereo matching into novel-view synthesis for high-quality geometry reconstruction. To this end this paper proposes a novel framework dubbed StereoNeRF which integrates stereo matching into a NeRF-based generalizable view synthesis approach. StereoNeRF is equipped with three key components to effectively exploit stereo matching in novel-view synthesis: a stereo feature extractor a depth-guided plane-sweeping and a stereo depth loss. Moreover we propose the StereoNVS dataset the first multi-view dataset of stereo-camera images encompassing a wide variety of both real and synthetic scenes. Our experimental results demonstrate that StereoNeRF surpasses previous approaches in generalizable view synthesis.
