摘　　要：文章针对无人机测图中高程精度低,尤其在山区,高程误差更大的问题,首次提出一种利用双层航线航拍方法,该方法从理论上把计算照片倾角的精度低的问题转化为不同航线间像点的位移精度问题,使倾角的计算精度得到很大程度的提升,最终达到提高高程精度的目的。In view of the low elevation accuracy in UAV mapping,especially in mountainous areas,the elevation error is larger.For the first time,an aerial photography method using double-layer routes is proposed.This method theoretically converts the problem of low accuracy in calculating the dip angle of photos into the displacement accuracy of image points between different routes.The calculation accuracy of the dip angle is greatly improved,andfinally the purpose of improving the elevation accuracy is achieved.
