【摘要】：随着人类社会的不断发展,加之我国城镇化正处于加速发展时期,数字城市的建设势在必行。校园的运转离不开学习、生活、教研、管理等各方面内容,灵活高效的校园系统可以协调校园各个部门之间的运转效率,为校园师生工作生活提供良好的基础。因此,需要基于重庆交通大学校园现有的信息资源,建设三维数字校园系统,实现空间信息展示、查找、分析以及图书、教室、商务信息管理等功能的数字校园系统。论文以重庆交通大学南岸校区为研究对象,基于GIS数据作为建模基础,首先使用City Engine三维建模软件快速批量制作各种建筑物的三维模型;然后将三维场景发布到ArcGIS Server地理空间服务器,采用B/S技术搭建系统环境,使用JAVAEE+SSM开发框架和MySQL开源数据库,利用ArcGIS Server for JavaScript作为GIS客户端开发平台,使用TomCat开源应用服务器,实现和验证地图功能、实景校园、电商平台、图书管理、教室管理等模块,最后实现重庆交通大学数字校园系统平台。论文主要工作如下:(1)采集和处理校园地理空间数据,分析三维数字校园开发所需要的技术平台,了解其工作原理,给三维数字校园开发提供数据基础以及开发平台技术支持;(2)首先对比分析各建模软件,然后基于City Engine三维建模软件运用CGA规则代码,对建筑物、道路、地物这三个方面进行快速建模,对必要的模型进行动态参数调整,最后快速批量化生成三维场景;(3)综合分析三维数字校园系统以及各个子系统功能,完成对系统的架构整体设计以及数据库的设计,实现地图功能、教室管理功能、图书馆管理功能、电子商务、权限管理功能等系统子功能的设计;(4)将三维场景发布到地理空间服务器,基于开源开发框架和技术实现客户端以及服务端功能的开发,然后对系统的各个功能模块进行验证,最后实现基于WebGIS的三维数字校园系统。
[Abstract]:With the development of human society and the acceleration of urbanization in China, the construction of digital city is imperative. The operation of campus can not be separated from learning, life, teaching and research, management and other aspects, flexible and efficient campus system can coordinate the operational efficiency of various departments on campus, and provide a good basis for the work and life of teachers and students on campus. Therefore, based on the existing information resources of the campus of Chongqing Jiaotong University, we need to build a three-dimensional digital campus system to realize the spatial information display, search, analysis, books, classroom, business information management and other functions of the digital campus system. This paper takes the south bank campus of Chongqing Jiaotong University as the research object, takes the GIS data as the modeling foundation, first uses the City Engine three-dimensional modeling software to make the three-dimensional model of various buildings quickly; Then the 3D scene is published to the ArcGIS Server geospatial server, and the system environment is built by using the technology of B / S, using the JAVAEE SSM development framework and MySQL open source database, using ArcGIS Server for JavaScript as the GIS client development platform, and using the TomCat open source application server. Realization and verification of map function, actual campus, e-commerce platform, book management, classroom management and other modules. Finally, the realization of Chongqing Jiaotong University digital campus system platform. The main work of this paper is as follows: (1) collecting and processing campus geospatial data, analyzing the technical platform needed for the development of 3D digital campus, understanding its working principle, To provide the data basis and development platform technical support for the 3D digital campus development. (2) compare and analyze each modeling software first, then use CGA code based on City Engine 3D modeling software, to the buildings, roads, These three aspects of the rapid modeling, the necessary dynamic parameters of the model adjustment, the final rapid batch generation of three-dimensional scene; (3) comprehensive analysis of the three-dimensional digital campus system and the functions of each subsystem, Complete the overall design of the system architecture and database design, achieve map function, classroom management function, library management function, e-commerce, (4) publish the 3D scene to the geospatial server, realize the development of the client and server functions based on the open source development framework and technology, and then verify the function modules of the system. Finally, a three-dimensional digital campus system based on WebGIS is implemented.
