摘　　要：无人机倾斜摄影技术可以获得结构面任意点的地理坐标和高程信息,根据地理坐标求解任意两点的方位角及距离,结合相应的高程可以获得基准点与一系列待测点形成的方位角和视倾角,选取最大视倾角及对应的方位角即为结构面产状。通过工程案例验证,该结构面产状量测方法的结果是准确的,现场实施方便可行。因此,无人机倾斜摄影技术测量结构面产状方法可以在高陡岩质边坡的工程地质测绘中广泛推广使用。The geographic coordinates and elevation information of any point on the structural plane can be obtained by the technology of UAV tilt photography.According to the geographic coordinates,the azimuth and distance of any two points can be calculated.Combining with the corresponding elevation,the azimuth angles and dip angles of datum point and a series of other points can be obtained.The maximum dip angle and the corresponding azimuth angle are the attitude of structure plane.Through the engineering practice verification,the results of the structural plane occurrence are accurate,and the field implementation of the method is feasible.Therefore,UAV tilt photography method can be widely used in engineering geological surveying and mapping of high and steep rock slope.
