Research on Non-iterative Calculating Method of Absolute Orientation for Unmanned Aircraft Vehicle Photograph
Author(s): 
Pages: 49-52
Year: Issue:  5
Journal: Hydrographic Surveying and Charting

Keyword:  无人机航空像片绝对定向非迭代求解定位精度;
Abstract: 利用无人机航空像片的模型点重心化坐标和地面重心化坐标构成单位四元数,通过最优化求解绝对定向旋转矩阵,并基于旋转矩阵解算平移参数和比例参数,实现绝对定向的非迭代解算.与传统方法相比,这种方法具有无需初始值、可靠性高等优点.实验结果表明,方法可以得到较高的解算精度,能够满足无人机航空像片定位的需要.
