摘要
随着高校建设的推进,具有更强交互性的信息化管理平台是必不可少的,建立以校园实景三维模型为基础的信息化管理平台能够满足用户需求.目前,大学电子地图及虚拟校园管理系统多以二维地图为基础,存在建筑实景联系不密切、用户体验真实感较差等问题.无人机技术的普及令倾斜摄影作业难度大幅下降,以某大学D区为例,通过无人机倾斜摄影搭建校园实景三维模型,基于Cesium框架,利用前后端分离方式实现了以实景三维模型为基础的校园建筑物和信息浏览与位置、距离、面积查询及可视域分析等功能.
Abstract
With the advancement of university construction,an information management platform with stronger interactivity is essential.The information management platform based on the three-dimensional model of the campus can meet more requirements of users.At present,the university electronic map and the virtual campus management system are mostly based on the two-dimensional map.There are some problems,such as the lack of close connection between the real scene of the building,and the poor sense of user experience,etc.The popularity of UAV technology has greatly reduced the difficulty of oblique photography.Through taking D District of a university as an example,the study builds a three-dimensional model of campus reality through UAV oblique photography.Based on Cesium framework,the functions of campus buildings and information browsing,location,distance,area query and visual field analysis based on the real three-dimensional model are realized by means of front-end and back-end separation.
