低空倾斜摄影测量在马沥村大比例尺测图中的应用

Application of Low-Altitude Oblique Photogrammetry in the Large-Scale Topographical Mapping of Mali Village

低空高分辨率倾斜摄影测量是近年来兴起的一项热门技术,以广州市白云区钟落潭镇马沥村大比例尺测图为例,介绍运用低空高分辨率倾斜摄影建模与大比例尺测图技术。在大比例尺地形图测绘方面,相较于传统航测和人工测图技术,该方法具有减少外业人员劳动强度,外业采集更自主、更高效的优势,为城市密集区域地籍调查、农村土地确权、国土规划用图等领域以及在其他不方便外业人员作业的山区、高危地势地区开展大比例尺测图提供参考。

Low-altitude high-resolution oblique photogrammetry is a popular technology that has emerged in recent years.With the large-scale topographical mapping of Mali Village,Zhongluotan Town,Baiyun District,Guangzhou City as an example,this paper introduces the use of low-altitude high-resolution oblique photogrammetry for modeling and the large-scale topographical mapping technology.In the mapping of large-scale topographical maps,compared with traditional aerial survey and manual mapping technologies,this method has the advantages of reducing the labor intensity of field workers and making field collection more independent and efficient,which provides a reference for carrying out large-scale topographical mapping in the fields of cadastral survey in urban intensive areas,rural land ownership confirmation and land planning mapping,as well as other mountainous areas and high-risk terrain areas where it is inconvenient for field workers to operate.
