| 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. |
