| 摘要: |
| 针对山区大面积复杂地形测量困难的问题,本文提出一种集无人机航空摄影测量、机载激光雷达扫描、三维模型立体测图等多种技术于一体的智能化测量模式,以外业采集海量数据、内业立体测图的方法代替了传统全野外数字测图。该方法在抽水蓄能电站地形测量工作中得以验证,具有相对成本低、时效高等突出的优势。经实测数据检验,地形图平面和高程精度均优于30 cm,符合现行地形图测量规范,同时还可以提供正射影像图、数字高程模型、数字表面模型、数字线划图等多种测绘地理信息产品,能够满足工程设计、施工的多项需求。 |

| Abstract: |
| In view of the difficulties in surveying large area complex terrain in mountainous areas, this paper proposes an intelligent surveying mode that integrates multiple technologies such as UAV aerial photogrammetry, airborne lidar scanning, three-dimensional model stereomapping, etc. The method of collecting massive data in the field and stereo mapping in the office replaces the traditional field digital mapping. This method has been verified in the topographic survey of pumped storage power station, and has the advantages of low relative cost and high timeliness. According to the test of the measured data, the plane and elevation accuracy of the topographic map are better than 30cm, which conforms to the current topographic map measurement specifications. At the same time, it can also provide a variety of surveying and mapping geographic information products, such as orthophoto map, digital elevation model, digital surface model, digital line drawing, etc., which can meet the multiple requirements of project design and construction. |
