为了验证转换结果的正确性,你可以使用MATLAB中的rotationMatrixToVector函数将旋转矩阵转换回旋转向量,并检查转换前后的旋转向量是否一致(考虑到浮点数运算的精度问题,它们可能不完全相等,但应该非常接近)。 matlab % 旋转向量 originalRotationVector = [0.1, 0.2, 0.3]; % 将旋转向量转换为旋转矩阵 rotationMatrix = ...

The revolution of a rotation matrix is often described with Euler angles, but can also be described in vector form using quaternions. Although there are many methods to perform a rotation, the most prevalent are based on directional cosine matrices and quaternions. ...
