Abstract
Aiming at the shortages of extracting coastline from LiDAR point clouds,a new method of using UAV DSM point clouds,combining with China offshore tide model is put forward.Firstly,the high resolution UAV images are processed following the computer vision method,and the high resolution and precision DSM point clouds are gained,which are used to produce DEM.Then,the coastline based on MHWS is abstracted based on isoline method.It is tested that the technology established in this research is capable of extracting nature coastline,and its accuracy meets the requirements of hydrographic survey specification.关键词
