以下是一个简单的伪代码,说明了quaternion到euler angles的转换: ```python import math def quaternion_to_euler(q): #计算旋转矩阵的元素 sinr_cosp = 2 * (q.w * q.x + q.y * q.z) cosr_cosp = 1 - 2 * (q.x**2 + q.y**2) roll = math.atan2(sinr
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...

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