基于无人机实景三维建模技术的智慧校园构建

The Intelligent Campus Construction Based on 3D Modeling Technology of Unmanned Aerial Vehicle

利用地面GPS设备和无人机搭载五镜头相机对某校区进行数据采集;对采集后的影像数据、POS数据和像控数据进行空三加密,并通过像控点特征匹配的方法对图像进行精度校正,应用Context Capture Master软件进行校区三维建模,并应用模型纹理编辑方法对三维模型进行渲染,渲染后的校区三维实景建模经过二次开发后可作为智慧校园的平台。

The ground GPS devices and the unmanned aerial vehicle carried the five-lens cameras are used to collect image data,POS data and image＇s control data.Those data are encrypted using aerial triangulation method.A feature matching method of image＇s control points is used to corrected model＇s precision. Campus＇ s 3 D model is built by using Context Capture Master software and rendered by using its model texture editing method.It can be used as the smart campus platform after secondary development.
