specific Embodiment approach 1

[0078] Before starting the regional construction and building perspective 3D model modeling work, it is necessary to collect materials first, in order to improve the difficulty of material query during the actual modeling. The details are to collect as many (1) regional locations as possible; (2) regional boundaries; (3) regional construction / building layout CAD drawings; (4) on-site text descriptions, photos, and videos by using legal and compliant means; 5) CAD drawing of the layout of each floor of the building; (6) Appearance measurement and description information of various facilities.

[0079] In the stage of regional layout, we need to establish the regional boundaries, and then draw the boundaries and basic information of outdoor structures and buildings within the regional boundaries. The steps are as follows: (1) use the two-dimensional geographic information system to locate the modeling area; (2) load the appropriate base map in the geographic information system t...

Abstract

The invention discloses aregional construction and building integral perspective three-dimensional model modeling method, which comprises an area layout stage: an area boundary needs to be established, and then boundaries and basic information of outdoor construction and building are described in the area boundary; in the stage of facility placement: building / building floors are selected one by one, and then some special attributes of facility types are described, so that modeling of facility entities is completed; and in the stage of parameter configuration: building / building floors are selected one by one, each facility space model is selected one by one, and other attributes of the facility space model are supplemented according to the type of the facility. The business operation difficulty of large-scale building overall three-dimensional model modeling is reduced, the existing two-dimensional geographic information system technology, image maps and vector maps, building / construction design CAD resources and facility three-dimensional model library resources are reasonably utilized through the process, and the efficiency of large-scale building overall three-dimensional model modeling is effectively improved.

Description

technical field [0001] The invention relates to the field of information technology auxiliary software and simulation software, in particular to a regional-level construction and a modeling method for a three-dimensional perspective model of an overall building. Background technique [0002] At present, the technology and application of CAD architectural drawing (such as Autodesk AutoCAD, Beihang CAXA electronic drawing board) have been widely developed, and the industrial construction and its supporting design industry can already realize the precise two-dimensional or 3D modeling, simulation analysis and BIM collaborative application (such as Autodesk Revit, Glodon Co-Architect). [0003] At the same time, GIS geographic information systems (such as Cesium, Gaode map) have also been widely used, which can load images and vector basemaps (such as Tiantu, Gaode) and use vector spatial primitives for geographical features such as buildings, landforms, and rivers. (Polygon, l...
