Method for setting up three-dimensional virtual scene of railway engineering project

Abstract

The invention provides a method for setting up a three-dimensional virtual scene of a railway engineering project. The method includes: S1, collecting relevant data of the railway engineering project and determining model attribute information of the railway engineering project according to the data; S2, according to the determined attribute information, generating a three-dimensional model base of the railway engineering project and a peripheral three-dimensional environment of the three-dimensional model base, and conducting model matching, model posture adjustment and model stretching; and S3, by unifying a coordinate system in a three-dimensional geographic information system (GIS) platform, the three-dimensional model base of the railway engineering project and the peripheral three-dimensional environment are combined so as to display a set scene. The method has the advantages of checking effects of a peripheral environment of a high speed railway on the railway directly; displaying information of bridges, roadbeds, tunnels and culverts visually and meticulously; achieving engineering project unified information retrieval; reducing labor cost in a modeling process, and improving setting up efficiency of the three-dimensional environment; and guaranteeing display accuracy of railway engineering project information.

Description

Technical field [0001] The invention belongs to the technical field of engineering design, and particularly relates to a method for quickly building a three-dimensional virtual environment of a railway engineering project. Background technique [0002] High-speed railway public works are the basic environment for railway operation, including railway bridges, subgrades, tunnels, culverts, track slabs, tracks and other facilities and equipment. In the past, the railway department used two-dimensional CAD drawings to display the plane, elevation and section of public works projects. However, viewing high-speed railway public works through CAD drawings cannot be combined with the surrounding topography and landforms, and therefore, it is not possible to view the complete picture of high-speed railway public works engineering equipment completely and intuitively. [0003] With the continuous development of virtual reality technology, more traffic engineering construction uses three-dim...
