| 摘 要： | 作为国际测绘领域近些年新兴的高新技术，倾斜摄影测量技术已应用于城市快速三维建模中。由于目前常用的大比例尺地形图测绘方法不能同时满足快速成图的时间和成本要求，本文提出了一种利用倾斜摄影测量技术测绘大比例尺地形图方法，充分发挥无人机倾斜摄影测量技术灵活、成本低、高效的优点，倾斜影像可自动生成三维模型和点云，简化了后续绘图工作。评定试验得到的岢岚县大比例尺地形图可知，成果平面精度达到0.140 m，高程精度达到0.150 m，符合大比例尺地形图精度要求，适合快速测绘小区域大比例尺地形图。

| Abstract: | Oblique photogrammetric technique is an emerging technology in recent years in the international surveying and mapping field,already used for quick construction of 3D city model.Given the common methods of surveying and mapping large-scale topographic map cannot simultaneously meet the time and cost requirements, this paper proposes a method based on oblique photogrammetric technique.By the advantages of flexibility,low cost and high-efficiency of unmanned aerial vehicle(UAV) oblique photogrammetric technique, the oblique images can automatically generate the three-dimensional model and point cloud by software. The assessment results of the Kelan County large-scale topographic map in experiment shows that the plane accuracy is 0. 140 meters and elevation accuracy is 0.150 meters,meeting the requirements.The method is suitable for surveying and mapping the large-scale topographic map of small areas. |
