摘要

对三线阵测绘相机热光学试验交会角测试系统进行了研究，设计了试验测试系统，研究了交会角的测量方法，提出空间交会角测量方法即定量检测法。详细地阐述了针对测绘相机热光学试验热真空试验设备和光学测量场等测试系统要求，特别是平行光管的改造和特种分划板的要求。同时，描述了三线阵测绘相机热光学试验前的需准备工作。利用Labview软件编制数据采集系统，采用定量测量法对三线阵测绘相机交会角进行了测量。结果表明，测试相机在工况转变后交会角的变化在1″的范围内。综合来看，该测量方法可以准确得到相机交会角的变化量，测量数据对三线阵立体测绘相机在轨测量及地面影像分析提供了可靠的分析依据

Abstract

Making research on space intersection angle measurement system for three-line mapping camera in thermal-optical test. Designing the test system and making research on the test method for intersection angle. The method for quantitative measurement is put forward. The requirement of thermovacuum test equipment and optical measurement field is interpreted in detail

especially the collimator and special reticle. At the same time

the needed preparation is issued before thermal-optical test. The measurement software system is made with Labview software. The three–line mapping camera intersection angle is tested with quantitative measurement. The results show that the change of intersection angle is below when the temperature operating condition is changed. In a word

quantitative measurement method can get the accurate change of intersection angle. The measurement data can benefit to the analysis on earth.
