欧拉角(Euler angles)是一种描述三维空间中物体旋转的数学工具,由瑞士数学家莱昂哈德·欧拉提出。它通过三个绕坐标轴的连续旋转角度来定义物体从初始方向到目标方向的姿态变化。
定义与组成
欧拉角由三个独立的角度参数构成,通常分为以下两类描述方式:
旋转顺序与坐标系
应用场景
若用欧拉角描述手机旋转:
如需数学公式表达,可参考经典欧拉角参数化:
$$
R = R_z(phi) cdot R_x(theta) cdot R_z(psi)
$$
其中$R_x$、$R_z$表示绕X轴和Z轴的旋转矩阵。
欧拉角也称为欧拉旋转角,是描述物体在三维空间中旋转的一种方法。欧拉角由三个旋转角度组成,分别是绕x轴旋转、绕y轴旋转和绕z轴旋转的角度。
欧拉角的英文解释为Euler angles,发音为 /'ju:lər ˈæŋɡlz/。
欧拉角被广泛地应用于物体的仿真、动画和控制等领域,是一种重要的欧几里得空间中的旋转表示方法。
