摘要
通过倾斜摄影测量手段,提高山洪灾害调查的效率,丰富调查成果。采用自主研发设计的组合倾斜摄影相机采集调查区域影像,运用专业软件对倾斜摄影数据实施空中三角测量及全自动数据生产,生成真三维模型、真正射影像、数字高程模型等成果,辅助进行山洪灾害调查调查,有效地提高了调查效率,丰富了调查成果。在应用中通过实地检测,验证了成果精度,符合山洪灾害调查要求。
The purpose of this paper is to increase the efficiency of Mountain Torrent Disaster, and to enrich the investigation results by oblique photogrammetry. The combined tilted-cameras which was developmented independently was used in this investigation to obtain images. Then, aerotriangulation and data were made by professional software automatically. Real 3-D mode, ture orthophoto and digital elevation model were generated in the meanwhile. The results shown that the efficiency of Mountain Torrent Disaster is in-creased and the investigation results are enriched Thus, the application of oblique photogrammetry in Mountain Torrent Disaster is re-liable and effective.
