【摘要】：隨著地理信息技術(shù)、圖形學(xué)理論及計算機科學(xué)的發(fā)展，可視化技術(shù)成為GIS的一個重要研究方向，并應(yīng)用于數(shù)字城市、交通、電力等各個領(lǐng)域，在各行業(yè)的信息化、可視化建設(shè)中起到重要作用。 本文結(jié)合蘭州交通大學(xué)本部建筑物可視化信息管理系統(tǒng)課題，利用圖形平臺進行建筑物立體建模，在ArcGIS中進行二維和三維地圖制作，采用ArcGIS Engine作為系統(tǒng)的開發(fā)組件，運用C#語言進行二次開發(fā)，實現(xiàn)對建筑物的瀏覽、查詢、圖形編輯、屬性修改及漫游等功能，為學(xué)校職能部門提供信息查詢、校園規(guī)劃、信息管理平臺。主要完成以下幾方面工作: （1）通過對三維空間數(shù)據(jù)模型進行分類，分析各類建模方法；結(jié)合AutoCAD和3DMAX建模軟件，針對樓房等構(gòu)筑物的特點，，研究拉伸、掃掠、放樣及旋轉(zhuǎn)建模方法；在SketchUp建模環(huán)境中，探討點狀、線狀及面狀要素的建模方法，并對立體模型進行材質(zhì)和紋理貼圖方法研究。 （2）采用不同的圖形平臺繪制校園平面圖和進行建模，在開發(fā)環(huán)境下進行圖形組裝和拼合時，解決AutoCAD、3DMAX、SketchUp及ArcGIS軟件間圖形轉(zhuǎn)換中存在的問題，實現(xiàn)不同格式的圖形轉(zhuǎn)換，建立校園地理信息系統(tǒng)的空間、屬性數(shù)據(jù)庫。 （3）運用ArcEngine組件和C#語言對ArcGIS進行二次開發(fā)，探討ArcGIS類庫的引用、ArcGIS控件的加載、控件的綁定以及在容器中嵌入ArcGIS控件等方法，實現(xiàn)校園建筑物在二維場景定位及其屬性的查詢、漫游、縮小、放大等操作；實現(xiàn)對平面圖形進行測距、編輯等操作，并利用工具條和菜單進行調(diào)用；在三維場景中實現(xiàn)旋轉(zhuǎn)、縮放、瀏覽等操作。 （4）以蘭州交通大學(xué)本部建筑物可視化信息管理系統(tǒng)開發(fā)為例，對系統(tǒng)框架和功能進行設(shè)計，在AutoCAD和3DMAX中進行繪圖和建筑物實體建模，將圖形轉(zhuǎn)換到ArcGIS中，運用C#語言和ArcGIS Engine開發(fā)組件，實現(xiàn)校園建筑物可視化信息管理系統(tǒng)的開發(fā)。
[Abstract]:With the development of geographic information technology, graphics theory and computer science, visualization technology has become an important research direction of GIS, and has been applied in many fields such as digital city, transportation, electric power and so on. In the industry of information, visualization construction plays an important role. Based on the subject of building visual information management system of Lanzhou Jiaotong University, this paper uses graphic platform to build three-dimensional model and makes 2D and 3D maps in ArcGIS. ArcGIS Engine is used as the development component of the system, and C # language is used for the secondary development. The functions of browsing, querying, graphic editing, attribute modification and roaming are realized. Provide information inquiry, campus planning, information management platform for the school functional departments. 1) analyzing all kinds of modeling methods by classifying 3D spatial data models; Combined with AutoCAD and 3D Max modeling software, according to the characteristics of buildings and other structures, the drawing, sweep, lofting and rotation modeling methods are studied. In the SketchUp modeling environment, the modeling methods of point, line and surface elements are discussed, and the material and texture mapping methods of the stereo model are studied. Using different graphic platforms to draw the campus plan and model, in the development environment for graphic assembly and assembly, to solve the AutoCAD 3DMAX. The problems existing in graph conversion between SketchUp and ArcGIS software, the realization of graphic conversion in different formats, and the establishment of space and attribute database of campus GIS. 3) using ArcEngine component and C # language to develop ArcGIS for a second time, discuss the ArcGIS class library's reference and the loading of ArcGIS control. The binding of the control and the embedding of the ArcGIS control in the container can realize the query, roaming, zooming and zooming of the campus buildings in the two-dimensional scene. To realize the ranging, editing and other operations of the plane graphics, and the use of toolbar and menu to call; In the three-dimensional scene to achieve rotation, scaling, browsing and other operations. Taking the development of building visual information management system of Lanzhou Jiaotong University as an example, the frame and function of the system are designed. Drawing and building entity modeling are carried out in AutoCAD and 3D Max, graphics are transformed into ArcGIS, and components are developed by using C # language and ArcGIS Engine. The development of visual information management system for campus buildings is realized.
