The invention relates to a headless spinning flight oblique photography aerial photography method for an unmanned aerial vehicle. The unmanned aerial vehicle carrying asingle-lens camera adopts a headless spinning flight mode; A direction deflection angle of a camera lens is adjusted by utilizing self-rotation of the unmanned aerial vehicle body when flying to the target area at a constant speed along the bow-shaped air route, the pitching angle of the camera lens is adjusted to be vertically downward and inclined by 45 degrees at a set time interval, an image of five different visual angles including a vertically downward angle and four inclined angles is acquired, and aerial image acquisition of oblique photography three-dimensional modeling is performed on a target area. According to the method, a common civil unmanned aerial vehicle can be used for carrying out one-frame bow-shaped air route flight on the target area, data acquisition of five-angle photographing three-dimensional modeling aerial images can be completed, the photographing efficiency of oblique photography is greatly improved, and the photographing cost is reduced.
本发明涉及一种无人机无头自旋飞行倾斜摄影航拍方法,搭载单镜头相机的无人机采用无头自旋飞行模式,对目标区沿弓字形航线匀速飞行过程中,利用无人机机身的自旋转调节相机镜头的方向偏转角,并在设定的时间间隔调节相机镜头俯仰角度为垂直向下和倾斜45度,获取一个垂直向下加四个倾斜角度五个不同视角的图像,对目标区进行倾斜摄影三维建模的航拍图像采集。本发明方法可实现使用普通民用无人机对目标区进行一架次弓字形航线飞行,即可完成五个角度的拍照三维建模航拍图像的数据采集,大大提高了倾斜摄影的拍摄效率、降低了拍摄成本。
