基于无人机倾斜摄影技术的城市三维实景建模研究

The Research of Urban 3D Real Scene Modeling Carried out by Using UAV Tilt Photography Technology

传统城市三维建模工作存在周期长、效率低等问题,已无法满足数字城市、智慧城市的发展需求。随着近年来无人机倾斜摄影技术的发展,国内许多城市采用无人机倾斜摄影技术实现城市三维实景模型的建设。以此为出发点,对城市小场景、重点区域,利用消费级无人机进行三维实景建模工作,详细阐述了该方法的技术路线、关键点及精度评价等内容,为相关工程提供技术参考。

Traditional 3D city modeling work has the problems of long cycle and low efficiency,which can no longer meet the development needs of digital city and smart city.With the development of UAV tilting photography technology in recent years,many cities in China have adopted UAV tilting photography technology to realize the construction of urban 3D real scene model.Taking this as the starting point,this paper studies the method of using consumer UAVs for 3D inter-scene modeling in small urban scenes and key areas,and expounds the technical route,key points and accuracy evaluation of this method in detail,so as to provide technical reference for related projects.
