Problems solved by technology

Existing autostereoscopic display systems cannot fully achieve true real-time display. First, the collected video is processed by PC software to extract the depth information of the scene, and then the depth information is used to generate and save the stereoscopic video. Finally, the generated Stereoscopic video for playback

Abstract

The present invention discloses a binocular vision auto-stereoscopic display system. The system comprises a binocular camera, an interface conversion circuit, an FPGA acceleration circuit and an auto-stereoscopic display, wherein the binocular camera is used for collecting real scenes, and transmitting collected videos to the interface conversion circuit through an HDMI interface; the interface conversion circuit is used for transmitting the received videos to the FPGA acceleration circuit through an LVDS interface; the FPGA acceleration circuit is used for receiving the videos, processing the videos frame by conducting frame through stereo matching, multi-view generation and stereoscopic image synthesis in sequence, and outputting the finally synthesized stereoscopic image to the auto-stereoscopic display. A watcher can perceive a stereoscopic effect when standing in corresponding position in front of the stereoscopic display to watch. The auto-stereoscopic display system uses an FPGA to support parallel and pipeline processing characteristics, thereby realizing real-time auto-stereoscopic display. An experimental result shows that the frame rate of displaying a stereoscopic video with the resolution of 1920*1080 by the present invention is about 30 frames/second.

Description

technical field [0001] The invention belongs to the technical field of image processing, and more specifically relates to a binocular vision autostereoscopic display system. Background technique [0002] With the progress of science and technology, the digital multimedia technology is constantly developing, and now 3D video applications have appeared in people's lives, such as in entertainment, military and medical fields. When watching general stereoscopic video, people need to wear auxiliary equipment such as red and blue glasses or polarized light glasses, when the viewer watches for a long time, they will feel tired, which limits the popularization and application of stereoscopic video display technology. [0003] The so-called autostereoscopic display technology refers to a technology in which the viewer can perceive the three-dimensional effect by directly observing the display screen without any auxiliary equipment, that is, naked-eye 3D technology. The autostereosco...
