摘要
本文介绍了低空摄影测量在火电厂地形测量的应用尝试及数据处理方法。结合现代航空摄影测量技术的发展,分析了低空摄影测量的特点;结合火电厂地形图测量的实际情况,分析了低空摄影测量的作业流程,对通过低空摄影测量获得的高程数据进行了精度评定,提供了利用外业实测高程数据对低空摄影测量高程数据进行拟合从而提高高程数据精度的处理方法。
This paper introduces the application of topographic survey and data processing methods by Low-altitude UAV photogrammetry at thermal power plant.Compare with modern aerial photographic measurement technology,the paper analyzed the characteristics of low-altitude aero-photogrammetry and low-altitude photogrammetric work flow combined with measurement of power plant topographic map.By assessing the precision of the low-altitude photogrammetric elevation data,provide the data processing method of improving the precision by filed elevation data and regional linear fit method.
