【摘要】：常规校园管理系统缺乏对空间信息的处理和分析能力,展示给用户的界面或数据不够生动直观。本文以大连海事大学为应用对象,利用虚拟现实技术、地理信息系统技术研究虚拟校园漫游及信息显示系统。所做的主要工作如下：首先,借鉴Google Earth软件的思路,通过对影像数据的获取与组织、影像数据与高程数据的叠加等关键技术的搭建了三维数字地球。其次,利用Creator软件进行校园场景建模,基于osgEarth软件,采用坐标变换及细节层次等技术实现了结合数字地球的校园场景显示与漫游。第三,在矢量数据栅格化显示技术的研究基础上实现了漫游系统中地理信息的显示；对于常规的校园信息,通过判断用户的鼠标拾取进而利用ADO技术访问数据库,实现信息的交互显示。基于以上研究,本文构建出了一个生动逼真的三维虚拟校园场景,同时将一些常用的校园信息融入到虚拟场景中,实现图文并茂的信息查询与显示,提高了用户的体验感与交互性。本文所做工作对于校园的数字化、信息化建设有一定的促进和借鉴作用。
[Abstract]:The traditional campus management system lacks the ability to process and analyze spatial information, and the interface or data displayed to users is not vivid and intuitive. This paper takes Dalian Maritime University as the application object, using virtual reality technology and GIS technology to study the virtual campus roaming and information display system. The main work done is as follows: Firstly, using the idea of Google Earth software for reference, the 3D digital earth is built through the key technologies such as the acquisition and organization of image data, the superposition of image data and elevation data, and so on. Secondly, Creator software is used to model the campus scene. Based on osgEarth software, coordinate transformation and detail level technology are used to realize the display and roaming of campus scene combined with digital earth. Thirdly, on the basis of the research of vector data raster display technology, the geographical information display in roaming system is realized, and for the normal campus information, the database is accessed by judging the user's mouse pick-up and then using ADO technology. Realize the interactive display of information. Based on the above research, a vivid 3D virtual campus scene is constructed in this paper. At the same time, some common campus information is integrated into the virtual scene to realize the information query and display. Improve the user's experience and interaction. The work done in this paper can promote and draw lessons from the digitization and information construction of campus.
