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.
