Connotation,Classification and Grading of 3D Real Scene

实景三维中国是国家新型基础设施建设的重要组成部分,是为国民经济社会发展和各级各部门信息化提供的统一的空间基底,也是国家新型基础测绘产品体系中标准化的、典型的产品。本文在国家新型基础测绘体系建设武汉试点实践的基础上,结合武汉市20多年来三维产品的生产和应用服务,阐述了关于实景三维内涵的思考认识,将实景三维产品分为倾斜三维、仿真三维和视频三维,划分地形级、城市级(框架级)和部件级(单体级),并与传统三维产品相对比,进而介绍了实景三维武汉建设的总体布局与生产思路。

3D real scene is an important part of the national new infrastructure construction.It is a unified spatial base for the national economic and social development and the informatization of all levels and departments.It is also a standardized and typical product in the national new fundamental surveying and mapping product system.Based on the Wuhan pilot practice of the national new fundamental surveying and mapping system construction,combined with the production,application,service of Wuhan for more than 20 years,this article expounds some opinions about the 3D real scene,divide them into oblique photography 3D,simulation 3D and panoramic video map,and divide them into terrain level,city level(frame level)and component level(single level),contrasts with traditional 3D products and introduces the overall layout and production methods of the 3D real scene Wuhan in detail.
