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...
返回围绕 z 轴旋转 euler.z 度、围绕 x 轴旋转 euler.x 度、围绕 y 轴旋转 euler.y 度(按此顺序)的旋转。可以从四元数中读取欧拉角。注意:如果该欧拉旋转出现万向节锁,会导致四元数返回的EulerAngle异常 示例 fromcommon.utils.mcmathimportQuaternion q=Quaternion.Euler(30,15,45)# 创建一个先围绕z轴旋...
