Discussion on the Analysis and Processing of Problems in Terrain-level 3D Real Scene Production
In recent years,satellite remote sensing technology has developed rapidly,and high-resolution satellite stereo images are widely used in smart cities,environmental monitoring,disaster assessment,agricultural monitoring,climate change,3D real scene construction,etc. In this paper,taking the terrain-level 3D real scene construction pilot area in Jilin province as an example,the production methods and 3D products (DEM,DSM and DOM) of terrain-level 3D real scene production are analyzed and summarized by using high-resolution satellite stereo images. From the perspective of production technology and methods,the paper expounds the production tasks,content requirements,production workflow and technical methods of terrain-level 3D real scene production,and puts forward solutions and suggestions according to the problems in production,which has certain reference value.
