实时单目狭缝光栅自由立体显示系统的设计

Design of the Auto Stereoscopic Display System for a Single Camera

设计一种半自动式的单目自由立体显示系统。采用FPGA(现场可编程门阵列)实现视频源采集、存储、立体合成和显示,显示器采用倾斜狭缝光栅液晶显示器。基于灰度信息从图像中获得深度信息,据深度信息投影原理以及仿人眼成像原理加入双眼视差来重构立体图。解决了视角窄、黑带以及处理速度慢的问题。

This paper presents the hardware implementation of an auto stereoscopic display system for video capture, storage, stereogram reshaping and display through FPGA by a single camera. The slanted parallax barrier is used in the display. In the algorithm proposed, a 2D image is converted to a series of disparity views by depth information calculation based on gray level information and adding disparity according to depth information projection principle and human eye imaging principle, some problems including narrow view angle, black zone, and slow processing rate are solved. Results show the system has the advantage of good effectiveness and real time. Thus, it has a wide application.
