3D relief model；
(2) architectural plane profile and the road network in orthography are sketched the contours of；
(3) urban planning Software Create 3D buildings model and road network are used.
Step (1) specifically: the orthography and Arc for being shot unmanned plane using Esri Arc GIS Pro Survey and map software
The satellite map of GIS Online is spliced, and the 3D relief model with image information and elevation map is generated.
Step (2) specifically: the architectural plane in satellite map is obtained by Open Street Map open source map web site
Profile and road network sketch the contours of architectural plane profile and the road network in orthography by Auto CAD graphics software later
And export as Auto CAD DXF file.
Step (3) specifically: Auto CAD DXF file is imported into Esri City Engine urban planning software, is passed through
Esri City Engine CGA sequencing modeling rule in Esri City Engine urban planning software is according to Auto
The reference line transect of CAD DXF file generates 3D buildings model and road network, and according to Esri City Engine urban planning
Branch in Esri City Engine CGA sequencing modeling rule in software and generate vegetation and essay.
After step (3) further include:
(4) Esri City Engine urban planning software is passed through into Esri Pal ladio plug-in unit and Houdini 3D beauty
The module that art software establishes C++ bottom relies on, the model for enabling the CGA in Esri City Engine urban planning software to generate
More model details are added in Houdini 3D fine arts software., to reach the application requirement of video display and electronic game.
(5) 4 plug-in unit of Unreal Engine is switched to by Houdini 3D fine arts software, parameter will be can be customized by users
Houdini HDA file import 4 game engine of Unreal Engine in.So far, high-precision, it can draw in game
By (such as to single building pattern, the adjustment of shape etc.) of user's adjustment parameter in holding up, position is put accurately in map, is built
The city 3D for building enormous amount creates in game engine to be finished.
The beneficial effects of the present invention are:
The creation method of 3D model of the invention can in high volume pass through rules of order creation building and vegetation in an implementation
3D model, the buildings model after generation can be put according to the position of real world, while build more at present can for the fineness of model
Model depending on changing Software Create is significantly increased, and can be used in electronic game and video display.
3D model creation of the invention is based on existing software rules, has UV and the textures applied to PBR process, ensure that mould
It puts and can pass through in the later period in strict accordance with the position on map in the position of the Picture Showing power of type, the 3D model formed after creation
Had technology is artificially adjusted, and in creation, the model of flood tide is generated by CGA rule, avoids artificial increased costs.
The creation side of 3D model of the invention is related by the software in terms of mapping, urban planning, 3d art and electronic game
Function connection is can solve through the invention when involved geographic range is huge, and asd number is huge, the requirement of model fineness
Height, creation when model geographical location accuracy requirement is high to the city 3D.
