光学测量大气折射带来的误差已成为限制高精度测量的主要因素。针对实时和事后数据处理两部分分别提出了两种修正方法, 并建立了折射误差修正模型及残差模型, 经试验验证和误差比对分析, 证明两种修正方法计算便捷, 模型准确, 均能提高实时和事后数据处理的精度。

High accuracy measurement is mainly limited by the error from atmospheric refraction. According to data processing parts in real time and afterwards, two correction methods are proposed respectively. And refraction error correction and residual error models are built. By experimental validation and error comparing analysis, the simple calculation process and accurate models can be got by using these two methods, and can enhance the accuracy of data processing in real time and afterwards.
