摘　　要：校园三维模型是“智慧校园”建设的关键技术之一。为解决建模方法存在的数据采集难度大、成本高及建模效率低等问题。以云南大学明远楼为例,利用消费级、轻小型无人机倾斜摄影测量技术,采取5架次航飞法,设置无人机航飞的镜头方向、航向、旁向重叠率、航高和航向重叠率,以采集高质量的照片数据,并通过Context Capture软件的建模功能,以获取高质量的三维模型。结果表明:消费级无人机具有实现倾斜摄影以及三维建模的能力,而且建模效果可以达到三维校园建设的要求。The three-dimensional model of the campus is one of the key technologies for the construction of“smart campus”.In order to solve the problems of difficult data collection,high cost and low modeling efficiency in modeling methods.Taking the Mingyuan Building of Yunnan University as an example,using consumer-grade,light and small unmaned air vehicle(UAV)tilting photogrammetry technology,adopt 5 flight flying method,set the lens direction,heading,side overlap rate,altitude and heading overlap rate of UAV flight.To collect high-quality photo data.Then use the modeling function of Context Capture software to obtain high-quality three-dimensional models.The results show that the consumer-grade UAV has the ability to achieve oblique photography and three-dimensional modeling,and the modeling effect can meet the requirements of three-dimensional campus construction.
