| 摘 要： | 为降低无人机飞行姿态较差对后续空三数据处理的影响，将计算机视觉多视几何理论引入传统摄影测量，将其三维数据处理结果作为摄影测量空三加密的初始数据，以提高空三加密的精度和可靠性。不同地面分辨率和不同地形特征的多个测区试验证明了所提方法的正确性，为实际应用提供了理论和实践参考。

| Abstract: | In order to reduce the influence of poor UAV flight attitude on subsequent aerial triangulation data processing, computer vision multi-view geometry theory is introduced into traditional photogrammetry, and its 3D data processing result is taken as initial data for aerial triangulation encryption in photogrammetry to improve the accuracy and reliability of aerial triangulation encryption.The accuracy of the proposed method is proved by the multi-zone test with different ground resolutions and different topographic features, which provides theoretical and practical reference for practical application. |
