摘要
研究目的:三维GIS技术已在数字城市等领域取得成功应用,铁路行业对其应用需求也日益强烈,相关科研工作也取得了一定的突破,但仍未实现广泛和成功的应用,其主要原因之一是:如何快速、精确构建面向铁路行业呈长距离带状分布的精细三维场景,为其提供一个开展三维应用的数据支撑平台。研究结论:(1)提出了一套面向铁路行业的三维场景快速构建一体化技术;(2)研发了一套三维GIS平台和一系列软件工具;(3)通过在中老铁路三维设计工作中的成功应用,验证了技术体系的可行性,为铁路行业三维GIS应用探索了一条可供选择的解决方案。
Research purposes： With the successful application of 3D GIS technology on Digital City area, the demand from railway industry is increasingly strong. Related researches have made some breakthroughs, but not yet achieved widely and successfully application. The main reason is how to quickly and precisely build a long 3D scene, to provide a data support platform for 3D application. Research conclusions： （ 1 ） A practical integrated technology is put forward in this paper to quickly build a 3D railway scene. （2） a series of three - dimensional GIS software platforms and tools appropriate are independently developed. The integrated technology and software platforms have been applied in China - Laos railway projects successfully. It verifies the feasibility of the technical system in this paper. So a solution for 3D GIS applications on the railway has been explored.
