摘要
在车载、舰载等运动载体或单兵警戒值守等狭窄空间,传统显示方法难以兼顾显示视场与显示分辨率。针对该问题,本文研究了一种基于变形目镜的全景/周视成像技术与系统。系统采用3路低照度摄像机+4 mm焦距镜头,构成150°左右的全景成像视场,基于FPGA处理平台完成全景图像解析、拼接、校正和显示等算法,实现视频图像大视场拼接与1/3缩放实时显示;由OLED微显示器、变形目镜组和大目镜组成的显示系统使视频图像横向扩大3倍,实时显示全景高分辨动态场景图像。实验系统对全景成像显示技术进行了验证,在军用和民用领域具有广泛的应用前景。
Abstract
In narrow spaces, vehicles, carriers or for single guards on duty, traditional displays have a dilemma wherein it is difficult to balance a display’s field of view and its resolution. This paper studies panoramic/periodic imaging technology and a system based on deformable eyepieces, which is expected to provide a technical solution to effectively solve the above problems. The system uses three low-light cameras with 4 mm focal length lens to form a panoramic imaging field of view of 150°. Panoramic image analysis, stitching, correction, and display are carried out by adopted FPGA processing platform. It also has a real-time zoom display; a display system consisting of OLED micro-displays, an anamorphic eyepiece group and large eyepiece enlarges the video image horizontally by a factor of 3 and displays a panoramic high-resolution dynamic scene image in real time. The experiment verifies the feasibility of a day and night panoramic imaging display. The system has a wide array of possible applications inside and outside of the military.
