摘要

由于单台高速摄像机无法满足高速测量领域对大视场、高帧频、高分辨力和高数据量处理的要求

本文对通过外视场拼接来实现大视场角目标测量的技术进行了研究。在分析和比较各种拼接方式的基础上

提出了由4个测量相机的外视场拼接实现大视场测量的系统方案。4台测量相机以"田"字型配置在跟踪架水平轴两端

拼接后在视场上实现了"一"字型大视场测量。采用提出的方案

设计和研制了外视场拼接测量系统样机。采用视场角为10的镜头进行视场拼接

实际拼接后最大视场为40(方位)10(高低);视差为360 mm时

目标距摄像机大于247 m无盲区

可以拍摄到完整的图像。

Abstract

As a single high-speed camera can not meet the requirements of high-speed target measurement for large fields

high frame rates

high resolutions and large volume data processing

the high speed target measuring technology completed by external field stitching was researched. On the basis of analysis and comparison of external field stitching methods

a ultimate scheme of external field stitching with external fields from four cameras was proposed. In the scheme

two cameras were mounted at one side along the horizontal axis of a 'T' type tracking frame and the others were at the other side. A prototype of external field stitching measuring system made of four lenses with 10field-angle was designed

and its actual stitching field of view is 40 (horizontal) 10 (vertical).When the parallax is 360 mm

the complete image can be obtained for the target over 247 m away from the cameras without blind spots.
