轻小型低空无人机航测航高计算方法研究

该文对数码相机的拍摄和成像原理进行了介绍,结合轻小型无人机航空摄影测量的特点,对航高与影像地面分辨率之间关系进行了研究,并对计算方法进行了实例验证,证明本方法的可行性,为轻小型低空无人机摄影测量飞行航高的确定提供了依据和技术支持。

In this paper,the principle of digital camera photography and imaging is introduced.Combining with the characteristics of aerial photogrammetry of light and small UAV,the relationship between line height and ground resolution of image is studied.The calculation method is verified by an example,which proves the feasibility of this method.It provides the basis and technical support for the determination of flying height in photogrammetry of light and small low altitude UAV.
