摘 要: 在山区,温度代表性误差是影响光电测距精度的主要因素。该文介绍一种利用近地面大气层的垂直温度分布模型估算测线的平均温度,进而有效削减山区光电测距温度代表性误差对测距精度的影响。 Representative error of temperature is main factor to affect precision of EDM in a mountainous area. An effective method to decrease representative error of temperature in EDM for mountainous region is given in this paper. The essential of the method is to compute average temperature of survey line by means of vertical temperature distributing model in near atmosphere. The effect of distance measurement precision by the error in EDM can be decreased usefully.
