摘　　要：针对传统的无人机航线设计大都只考虑垂直摄影的情形,没有考虑倾斜摄影的问题,该文结合滑坡地区的具体地形,对倾斜摄影的倾角以及主光轴方位角等相关参数进行了讨论与设定,并对倾斜摄影方式下的图像重叠率进行分析与对比,从而在确定重叠率后对无人机航线设计规划进行了研究,最终通过对比同一摄区垂直摄影与倾斜摄影的拍摄结果并分析。实验结果表明,对于单位摄区面积内,垂直摄影的密度为237.15张/km2,倾斜摄影的密度为206.69张/km2,同时可以明显发现单相机倾斜摄影的方式更有利于滑坡监测。Aiming at the problem that the traditional UAV route design only considers vertical photography,and does not take into account the problem of oblique photography,the route planning of oblique photography was considered with terrain factor in this paper,the inclination angle and principal optical axis azimuth were discussed and set through certain overlay rate between the 2 images,the final route was determined,finally the result of oblique photography route was compared with vertical photography route result.In a certain area,the density of picture in vertical ways was 237.15 photos per square kilometer,and the density of oblique ways was 206.69 photos per square kilometer,the oblique photography photo was more clearly and less geometric distortion,it is good for landslide monitoring.
