Problems solved by technology

The source of these multi-viewpoint information is a problem to be solved. If multiple cameras are used to collect images, the amount of information will increase sharply, and a better coding scheme needs to be designed. At the same time, it requires high transmission bandwidth and hardware requirements. The storage space requirement is large, so this solution is generally not advisable

Abstract

The invention discloses a real-time stereo image generating system, and belongs to the technical field of image processing. The real-time stereo image generating system comprises a multi-view generating module, a caching module and a stereo image synthesizing module. The multi-view generating module is composed of N parallel depth-image-based rendering processing units, and used for generating N virtual view images according to original image and disparity map information. The data of the generated virtual view images is stored into N dual-port dual-cache units of the caching module. The stereo image synthesizing module reads the data of the virtual view images from the caching module, synthesizes the N virtual view images into a stereo image which is applied to a lenticular grating auto-stereoscopic display for displaying. According to the real-time stereo image generating system, the characteristic that FPGA supports parallel and pipeline processing is used, thus the generation speed of the stereo image is improved, and the real-time processing performance of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and more specifically relates to a real-time stereoscopic image generation system. Background technique [0002] Now 3D video applications have appeared in people's lives, and can be seen in entertainment, military, and medical fields. When viewing general stereoscopic video, people need to wear auxiliary equipment such as red-blue glasses or polarizing glasses, thereby limiting the popularization and application of stereoscopic video display technology. 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. Autostereoscopic display technology not only enables the viewer to obtain a three-dimensional sense, but also facilitates viewing. It has broad development prospects and is a current research hotsp...
