基于无人机摄影技术的地理信息三维可视化研究

Research on 3D visualization of geographic information based on UAV photography technology

为了提高地理信息三维可视化的效率和清晰度,本文在无人机摄影技术的基础上开展相关研究。通过无人机拍摄获取地理信息数据,并对获取的地理信息数据进行融合处理,结合超文本链接标记语言、JavaScript和Web图形库等技术实现地理信息三维可视化展示。实验测试表明,基于无人机摄影技术的地理信息三维可视化方法得到的影像平均帧率更高,三维可视化效果更佳。

In order to improve the efficiency and clarity of three dimensional(3D)visualization of geographic information data,this paper conducts relevant research on the basis of Unmanned Aerial Vehicle(UAV)photography technology.The acquired geographic information is captured,fused and processed by UAV.The 3D visual display of geographic information data is realized by combining hypertext markup languages,JavaScript,web graphics library and other technologies.The experiment is proved that the proposed 3D visualization method of geographic information based on UAV photography technology has higher average frame rate and better 3D visualization effect.
