Experimental development of a multi-view stereo endoscope system

This paper reports on developing experimentally a multi-view stereo endoscope system that reconstructs once 3D data from each stereo image handled in the medical field, enhances the 3D data, and renders a set of multi-view images being available to an arbitrary multi-view glasses-free 3D display in contrast to a conventional stereo endoscope system being unavailable to multi-view displays. The developed system is similar to a CT reconstructing 3D data but is different in the respects that the former inputs one-shot stereo images with visible light to observe the surface of object in real-time while the latter inputs multidirectional projections with X-ray to observe the inside of object in non-real-time.
