摘　　要：无人机倾斜摄影测量技术在三维模型建立中存在高效、便捷等独特优势,已成为热门测量技术。为了探讨无人机倾斜摄影测量三维建模的精度,通过阐述无人机倾斜摄影测量三维建模原理与过程,并以某一历史建筑物为研究对象,通过大疆精灵4 RTK型无人机搭载高分辨率影像对目标物进行环绕飞行,采集各方位立面影像,并构建三维模型,研究重建后的E、N、U坐标与所测控制点坐标的残差大小与精度分析。结果表明,研究区域内的三位建模精度达到厘米级,可有效应用于建筑规划、文物保护修复等行业。UAV tilt photogrammetry technology has unique advantages such as high efficiency and convenience in the three-dimensional modeling,and has become a popular measurement technology.In order to discuss the accuracy of three-dimensional modeling of UAV tilt photogrammetry,this paper expounds the principle and process of three-dimensional modeling of UAV tilt photogrammetry.Taking a historical building as the research object,the DJI 4 RTK UAV is equipped with high-resolution images to fly around the target,collect the facade images of each orientation,and construct the three-dimensional model.The residual size of the reconstructed E,N and U coordinates and the coordinates of the measured control points and accuracy analysis are studied.The results show that the three-dimensional modeling accuracy in the study area reaches centimeter level,which can be effectively used in industries such as construction planning,cultural relic protection and restoration.
