| 摘 要： | 机载雷达点云的主要应用是生产数字高程模型(Digital Elevation Model,简称DEM).由于机载雷达所获得的雷达点云包括地面点和非地面点,所以在生产DEM之前要进行非地面点的滤除,在国外很多研究文献提出全自动或半自动的方法用来过滤地物点,保留地面点用以生成数字高程模型.

| Abstract: | The main application of light detection and ranging point cloud is the production Digital Elevation Model(DEM).Before producing DEM we must carry on a non-ground filtration because the light detection and ranging point cloud includes ground and non-ground points.In the overseas many research literature proposed the completely automatic or the semiautomatic method to filter the object point,and retain the ground point to produce the digital elevation model. |
