pip install numpy-quaternion 安装完成后,就可以在Python脚本中导入并使用它了。 基础用法 创建四元数 首先,来看看如何创建一个四元数。四元数由一个实部和三个虚部组成,可以通过多种方式创建: importnumpyasnpfromnumpy_quaternionimportquaternion# 从欧拉角创建四元数euler_angles=np.array([0.1,0.2,0.3])q1=qu...
```python from numpy import Quaternion q = Quaternion.from_euler_angles(angle1, angle2, angle3, degrees=True)```这将创建一个四元数，表示按照x-y-z顺序旋转angle1、angle2和angle3度。需要注意的是，角度的单位默认为弧度，可以使用degrees=True来指定单位为角度。除了x-y-z顺序，还有其他常见的旋转...

Finally, it is possible to derive the Euler angles from a quaternion using as_euler_angles, or create a quaternion from Euler angles using from_euler_angles— though be aware that Euler angles are basically the worst things ever.1 Before you complain about those functions using something other...
