Frame A to B
Frame B 的基向量 到 Frame A 的基向量
\[B = \begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{bmatrix} \Longrightarrow A = \begin{bmatrix} 0 & 0 & 1 \\ -1 & 0 & 0 \\ 0 & -1 & 0 \end{bmatrix}\]则 Frame B 到 Frame A 的 主动旋转 为
\[R_{AB}^a = A\]则 Frame A 到 Frame B 的 被动旋转 为
\[R_{BA}^p = R_{AB}^a = A\]通过在线工具 (https://www.andre-gaschler.com/rotationconverter/) 将 $A$ 转换为 Euler angles (radians, ZYX or YPR)
