摘要
人工测绘电力杆塔三维坐标有相当难度,这影响了地理信息系统在线路管理中的应用。简要介绍了航空数字摄影测量技术,阐述了基于航空数字摄影测量的电力杆塔定位技术的作业流程。经在宁波地区的实践表明,航空数字摄影测量技术较常规测量有显著优势,并取得了良好的应用效果。
Manual mapping 3D coordinate of an electric power tower has a little difficulty, this affects application of GIS in electric power line management. Aviation digital photographic measurement is briefly described, and work process of the tower position based on the measurement technology is elaborated. The practical use of the technology shows it has significant advantages compared with normal measurement and achieves good effects.
