base line measurement

基本解释

A laser collimating system supplies a base line which is used for coaxiality measurement.
激光准直系统的研制是为了提供大轴同轴度测量中需要的一条基准直线。
A high-precision base line indoor was build using double frequency laser interferometer as the measurement standards.
采用室内双频激光干涉仪为计量标准，建立了一条高精度室内基线。
The contrast analysis of measured results showed that the length of the image base line had no effect on the measurement of height difference under stereomodel.
测量结果的对比分析表明，象基线对立体模型下的地形高差测量没有影响，现用高差计算公式不能给出正确的结果。
