摘　　要：传统的地质灾害调查存在工作效率低、精度不足,并具有一定的危险性等问题。无人机的应用解决上述的大部分问题。无人机倾斜摄影测量技术具有高精度、高时效的特点,在地质灾害中得到广泛的应用。该文介绍无人机的基本操作、无人机数据的处理,并建立新安县畛河右岸某滑坡的三维模型。无人机生成的正射影像图具有地图几何精度和影像特征。在犀牛软件强大的网格建模功能下,由无人机生成的等高线到三维模型的建立变得简单而又高效。The traditional geological hazard investigation has some problems, such as low efficiency, insufficient precision, and certain danger and so on. The application of drones solves most of the above problems. UAV tilt photogrammetry has the characteristics of high precision and high time, so it has been widely used in geological disasters. This paper introduces the basic operation of UAV and the data processing of UAV, and establishes a three-dimensional model of a landslide on the right bank of Yihe River in Xin’an County. The orthophoto map generated by UAV has map geometric accuracy and image features. Under the powerful grid modeling function of Rhino, the establishment of contours generated by UAV to 3D model becomes simple and efficient.
