浅谈地形级实景三维生产中的问题分析及处理

Discussion on the Analysis and Processing of Problems in Terrain-level 3D Real Scene Production

近年来卫星遥感技术高速发展,高分辨率卫星立体像对广泛应用于智慧城市、环境监测、灾害评估、农业监测、气候变化、实景三维建设等领域。本文以吉林省地形级实景三维建设试验区为例,将利用高分辨率卫星立体像对进行地形级实景三维生产方法及3D产品(DEM、DSM、DOM)分析总结,从生产技术方法角度,阐述了地形级实景三维生产任务、内容要求、生产工作流程和技术方法,针对生产中出现的问题提出解决方案,具有一定的参考价值。

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.
