摘要
全景成像在特种车辆内夜间驾驶与观察、警戒监视等应用中具有广泛的应用需求。本文提出了一种基于OLED微显示器和变形目镜的全景图像显示方法,并设计了一套全景显示实验系统,通过图像处理模块完成全景图像数据的存储、缓存、图像预处理和传输,以OLED微显示器的子像素作为显示像素进行驱动信号重编码,实现全景灰度图像的水平3倍压缩显示,最后利用变形目镜将OLED微显示器上显示的压缩图像复原,以供人眼正常观察。实验结果表明: 采用现有系统搭建的变形目镜基本实现了双像素靶标条纹的亚像素分辨,并验证了本文全景显示方案的可行性。
Abstract
Panoramic imaging has been widely used in the applications of night driving, observation and surveillance in special vehicles etc. In this paper, a method of panoramic display based on OLED micro-display and anamorphic eyepiece is studied and proposed, and a set of panoramic display experiment system is designed. The image processing module is responsible for storing, buffering, pre-processing and transmitting the panoramic image data, and re-encoding the driving signal with the sub-pixels of the OLED micro-display as the display pixels. A horizontal 3× compression display of the panoramic gray image is realized in this paper. Finally, the compressed image displayed on the OLED micro-display is restored by anamorphic eyepiece for normal observation by human eyes. The experimental results show that the anamorphic eyepiece constructed by the existing system has not achieved the single-pixel resolution of the panoramic display, but the subpixel resolution of dual pixel target stripe has basically been achieved, and the feasibility of the panoramic display scheme proposed in this paper has been verified.
