四元数表示旋转矩阵，代替了传统的欧拉角解算外方位元素-Quaternion rotation matrix, Euler angles instead of the traditional elements of exterior orientation Solution

欧拉角和四元数的转换：输入偶欧拉角，按Rechnen，程序会自动将欧拉角转换为四元数，再得出最终的方位。-Euler angles and quaternion conversion: input dual Euler angles, press Rechnen, the program will automatically Euler angles conversion quaternion, and then come to the final orientation.
