摘　　要：在地理信息系统与地图学领域,精准的地形图具有重要意义,传统地形测绘方法在细节捕捉上存在局限性。为此,本文提出了一种基于倾斜摄影技术的大比例尺三维数字地形测绘方法。首先,通过无人机倾斜摄影技术采集大范围地理对象数据,并利用Smart 3D软件对获取的数据进行三维建模,构建真实的大比例尺地形模型,实现大比例尺三维数字地形图的测绘。实验结果表明,基于倾斜摄影技术的方法可有效建立三维地形模型,精度检测结果显示其均方误差为0.202 m,高程均方误差为0.257 m,平面均方误差为0.201 m,高程均方误差为0.197 m。In the field of geographic information systems and cartography,accurate topographic maps are of great significance.Traditional topographic mapping methods have limitations in capturing details.To this end,this paper proposes a large-scale three-dimensional digital terrain mapping method based on oblique photography technology.First,large-scale geographic object data is collected through unmanned aerial vehicle oblique photography technology,and the acquired data is three-dimensionally modeled using Smart3D software to construct a real large-scale terrain model and realize the mapping of large-scale three-dimensional digital terrain maps.The experimental results show that the method based on oblique photography technology can effectively establish a three-dimensional terrain model.The accuracy test results show that its mean square error is 0.202 m,the mean square error of elevation is 0.257 m,the mean square error of plane is 0.201 m,and the mean square error of elevation is 0.197 m.
