基于ODM和Cesium的无人机倾斜摄影建模及可视化

GIS随着计算机科学技术的发展尤其是Web技术和WebGL技术的发展,近些年正逐渐三维web化,但无法直接复用较成熟的二维WebGIS方案。本文提出一种Cesium结合ODM(OpenDroneMap)进行三维WebGIS开发的方案,通过ODM在服务端自动处理无人机倾斜摄影测量采集的影像数据,将处理后产生的倾斜模型、点云、DEM等数据进行数据管理,最后在客户端浏览器进行三维可视化。本文阐述两者的开发模式、使用方法、数据组织和软件框架,概述了在无人机数据倾斜建模及可视化中的应用。

Modeling and Visualization of Drone Oblique Photographic data Based on ODM and Cesium

With the development of computer science and technology,especially the development of Web technology and WebGL technology,GIS is gradually turning into 3D Web in recent years,but it is unable to reuse mature 2D WebGIS schemes directly.In this paper,a Cesium combined with ODM(OpenDroneMap)to develop 3d WebGIS is proposed.By using ODM to automatically process the image data collected by uav mapping at the server end,data management is carried out for the data generated after processing,such as the tilt model,point cloud and DEM,etc.Finally,3d visualization is carried out in the client browser.This paper describes the development mode,application method,data organization and software framework of the two systems,and summarizes their applications in uav data skew modeling and visualization.
