Sliding-aperture multiview 3D camera-projector system and its application for 3D image transmission and IR to visible conversion

摘要

Abstract: A new architecture of the 3-D multiview camera andprojector is presented. Camera optical system consistof a single wide aperture objective, a secondary(small) objective, a field lens and a scanner.Projector supplementary includes rear projection pupilforming screen. The system is intended for sequential2-D prospective images acquisition and projection whilethe small working aperture is sliding across theopening of the big size objective lens or the sphericalmirror. Both horizontal and full parallax imaging arepossible. The system can transmit 3-D images in realtime through fiber bundles, free space, and video imagetransmission lines. This system can also be used forreal time conversion of infrared 3-D images. With thissystem, clear multiview stereoscopic images of realscene can be displayed with 30 degrees view zone angle.!7
