摘　　要：利用大疆精灵4RTK无人机对河南农业大学文化路校区进行倾斜摄影,采用ContextCapture软件对采集到的数据进行了内业处理,得到了校园高分辨率三维实景模型。利用校园布设的GPS控制点和实测地物高度,对模型精度进行了精度分析。本研究利用Cesium云平台构建了实景三维校园地图服务,实现了三维虚拟校园的可视化和地物查询,并调用天地图API服务,实现了三维虚拟校园和天地图的无缝对接,提升了虚拟校园可视化效果。本研究实现了无人机倾斜摄影到实景三维模型构建,三维地图服务发布与数据查询,以其为智慧校园的构建提供技术支撑与参考。Tilt photography was carried out in Culture Road Campus of Henan Agricultural University using DJI Phantom 4 RTK UAV,ContextCapture software was used to process the collected data internally and obtain a high-resolution 3D realistic model of the cam-pus.The accuracy of the model was analyzed by using the GPS control points laid on the campus and the actual measured feature heights.The research results show that the Cesium cloud platform is used to build a realistic 3D campus map service to realize the vi-sualization and feature query of the 3D virtual campus,and calls the WorldMap API service to realize the seamless connection between the 3D virtual campus and WorldMap,which improves the visualization of the virtual campus.This study realizes the construction of realistic 3D model by the tilt photography of UAV,3D map service publishing and data query,and provides technical support and ref-erence for the construction of smart campus.
