摘　　要：无人机倾斜摄影构建的三维模型具有真实、不受模型形状和地形地貌的限制、生成速度快等优点。该文以北华大学东校区为例,采用基于五镜头的无人机航空倾斜摄影技术对地形高低起伏的校园进行三维实景精细模型的构建,并进行精度评定。此模型可以输出建筑物顶面和立面的数据及各个建筑物的具体位置,同时具备测距、定位等地图基础功能。后续可基于此校园三维实景模型进行二次开发,建立数字校园三维可视化平台,为智慧校园的建设提供底层数据支撑。The three-dimensional(3D)model constructed by UAV oblique photography has the advantages of being real,not limited by model shape and topography,and fast generation speed.In this paper,taking the East Campus of Beihua University as an example,the UAV aerial oblique photography technology based on five lenses is used to construct a three-dimensional fine model of the undulating campus,and the accuracy is evaluated.This model can output the data of the top and facade of the building,as well as the specific location of each building,and has the basic map functions such as ranging and positioning.Subsequently,we can carry on the secondary development based on this campus 3D real scene model,establish the digital campus 3D visualization platform,and provide the underlying data support for the construction of the intelligent campus.
