Abstract: This paper presents a novel image based stereoscopic rendering method without mosaic. It reduces the 3D plenoptic function in [Shum and He 1999] to a 2D plenoptic function, called impeller matching, by constraining camera motion to a planar circle. Impeller matching can provide a binocular panoramic vision. Comparing with panoramas and other image-based rendering methods, all kinds of geometric and photometric scene models are unnecessary to recover in our method, and image data can be captured very conveniently only by a single camera and tripod without mosaic processing. A prototype has been implemented including image capturing, binocular vision reconstruction, and real time impeller matching. It produces strong immersive binocular vision and proves to be a potentially better solution for stereoscopic display.
