摘要
研究探讨了倾斜摄影测量技术在大比例尺地形图测绘中的应用。结合无人机多镜头影像数据采集、空中三角测量、三维点云生成、建模等关键技术,实现了地形地貌要素的精确提取,并建立了完整的技术流程,包括数据获取、预处理、三维建模等环节。实践表明,该方法作业效率高、精度可靠、数据全面,可以为城市规划建设提供高质量的测绘基础数据支持。
The study explores the application of tilt photogrammetry technology in large-scale topographic mapping.By combining key technologies such as unmanned aerial vehicle multi lens image data acquisition,airborne triangulation,and 3D point cloud generation and modeling,precise extraction of terrain and landform elements has been achieved,and a complete technical process has been established,including data acquisition,preprocessing,3D modeling,and other links.Practice has shown that this method has high operational efficiency,reliable accuracy,and comprehensive data,and can provide high-quality surveying and mapping basic data support for urban planning and construction.
