摘要
本文以嫦娥一号激光测高数据为基础,研究滤波和插值的方法,以具有典型意义的虹湾、酒海、湿海3个地区的数据为例详细说明;提出基于可靠最小值的滤波方法,建立适合月球特点的数字高程模型(DEM),并进行质量评定。研究结果可为月球地形地貌的科学研究提供参考。
This paper studied the methods of filtering and interpolation based on the data of Chang' E-1 laster-measured height, and explained this process by taking laser-measured height data of Rainbow area, Mare Humorum and Mare Nectaris with typical signif- icance as examples. And the filtering method based on reliable minimum was put forward, the lunar digital elevation model ( DEM ) which is fit for the characters of the moon was built, and the quality of the DEM was evaluated finally. This paper could provide a refer- ence for the future scientific research on the topography of the moon.
