【摘要】：随着计算机与网络技术的发展，虚拟现实技术也变得日渐成熟。虚拟现实技术是一种崭新的人机交互方式，具有沉浸性、交互性和多感知性的特点。其中三维建模技术能够逼真的表达客观世界，但其缺少空间分析能力，因此地理信息系统与虚拟现实技术的结合成为研究热点之一。国内外许多数字城市的建设都是基于两者的结合实现的。虚拟校园作为数字城市其中的一个重要方面，可以生动的展现真实的校园景观，实现三维景观与三维地形的叠合，给用户带来强烈的视觉冲击。虚拟校园对于校园建设规划、校园决策支持以及日常管理具有重要作用。本课题主要研究了虚拟校园的构建过程，以成都理工大学主校区作为虚拟空间，根据虚拟现实地理信息系统技术原理，详细阐述了从数据采集到场景分析的整个过程，成功的建立了成都理工大学虚拟校园，并论述了建设过程中存在的问题。首先，本文通过绪论章节，详细阐述了虚拟校园建设的背景以及研究目的，，并结合国内外的研究现状明确了主要的研究思路和方法。其次，详细论述了虚拟校园建设的主要过程，依次从数据采集到数据处理，然后是主要地物模型的建立，再到将所有数据有机的组织到虚拟场景中。最后结合已经建立的虚拟校园进行场景的空间分析，体现了虚拟现实地理信息系统相对于简单三维建模技术的空间分析优势。在本文的结论部分，对本次课题所取得主要成果进行了总结，并且归纳了在实验过程中所发现的问题，并对以后主要的研究方向进行展望。本课题以成都理工大学为研究区域，获取校园范围内的影像数据、高程数据、建筑物属性数据，使用Sketchup软件进行建筑物建模以及其他地物的添加，最终将数据添加到ArcScene环境中建立整个虚拟校园，详细阐述了从数据采集到模型建立以及通过虚拟校园进行空间分析整个流程，这对于类似的虚拟校园的建立具有一定的借鉴意义。
[Abstract]:With the development of computer and network technology, virtual reality technology has become more and more mature. Virtual reality (VR) is a new way of human-computer interaction, which has the characteristics of immersion, interaction and multi-perception. 3D modeling technology can represent the objective world realistically, but it lacks the ability of spatial analysis. Therefore, the combination of GIS and virtual reality technology has become one of the research hotspots. The construction of many digital cities at home and abroad is based on the combination of the two. Virtual campus, as an important aspect of digital city, can vividly show the real campus landscape, realize the combination of 3D landscape and 3D terrain, and bring strong visual impact to users. Virtual campus plays an important role in campus construction planning, campus decision support and daily management. This topic mainly studies the construction process of the virtual campus, taking the main campus of Chengdu University of Technology as the virtual space, according to the technology principle of virtual reality geographic information system, expounds the whole process from data collection to scene analysis in detail. Successfully established the virtual campus of Chengdu University of Technology, and discussed the problems in the process of construction. First of all, through the introduction, this paper elaborates the background and research purpose of virtual campus construction, and clarifies the main research ideas and methods combined with the current research situation at home and abroad. Secondly, the main process of virtual campus construction is discussed in detail, from data acquisition to data processing, and then to the establishment of the main feature model, and then to organically organizing all the data into the virtual scene. Finally, the virtual campus has been established to carry on the space analysis of the scene, which shows the advantage of the virtual reality geographic information system compared with the simple three-dimensional modeling technology. In the conclusion of this paper, the main achievements of this paper are summarized, and the problems found in the experiment are summarized, and the main research directions in the future are prospected. In this paper, we take Chengdu University of Technology as the research area, obtain the image data, elevation data, building attribute data, use Sketchup software to model buildings and add other features. Finally, the data is added to the ArcScene environment to establish the whole virtual campus, and the whole process from data acquisition to model building and spatial analysis through virtual campus is described in detail. This has certain reference significance for the establishment of similar virtual campus.
