| 摘 要： | 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。

| Abstract: | The unit quaternions are constructed by the model gravity points and the ground gravity points in the unmanned aircraft vehicle(UAV) photograph.Furthermore,the rotation matrix is solved through optimizing.The parallel transfer parameters and the scale parameter are done based on unit quaternions rotation matrix.The method realizes the non-iterative calculating for Absolute orientation parameters.Comparing with the traditional method,the noniterative can calculate the parameters reliably without initial value.The experiment result shows that it could provide such precise value for orientation calculating as requirement of UAV photograph positioning. |
