本发明公开了一种用于无人机低空摄影的地形图测绘方法,能够快速确定摄影机倾斜的角度,并以此调节第一电磁铁的通电大小,使得摄影机受到多个方向的磁力推动,以接近原拍摄角度,且由于摄影模块被悬挂绳固定,使得摄影模块能够快速调整角度,同时摄影模块通过悬挂绳晃动时,会产生延迟效应,能够减少摄影模块的晃动幅度,根据并联电路中电流的大小调整第二电磁铁的通电大小,对摄影模块的角度进行二次调整,使得摄像机保持原拍摄角度,提高在低空摄影时拍摄的测绘图的质量,并且通过第一电磁铁和第二电磁铁的联合作用,使得摄影机在无人机移动时,减少晃动保持稳定。

    The invention discloses a topographic map surveying and mapping method for low-altitude photography of an unmanned aerial vehicle, which can quickly determine the inclination angle of a camera and adjust the power-on magnitude of a first electromagnet, so that the camera is pushed by magnetic forces in multiple directions to approach the original shooting angle, and a shooting module is fixed by a suspension rope, so that the shooting angle is not influenced. Meanwhile, when the photographing module shakes through the suspension rope, a delay effect can be generated, the shaking amplitude of the photographing module can be reduced, the power-on magnitude of a second electromagnet is adjusted according to the magnitude of current in a parallel circuit, and the angle of the photographing module is secondarily adjusted, so that the camera keeps the original photographing angle; and through the combined action of the first electromagnet and the second electromagnet, the shake of the camera is reduced and the camera is kept stable when the unmanned aerial vehicle moves.
