通过运行这段代码,你可以验证自定义函数 quaternionToRotationMatrix 是否正确地实现了从四元数到旋转矩阵的转换。如果两个旋转矩阵相等,那么函数就是正确的。
If the input is a matrix, each row is a quaternion vector of the form q = [w x y z], with w as the scalar number. Example: [0.7071 0.7071 0 0] Output Arguments collapse all rotm— Rotation matrix 3-by-3-by-n matrix Rotation matrix, returned as a 3-by-3-by-n matrix ...
表示三维空间的旋转有多种互相等价的方式,常见的有旋转矩阵、DCM、旋转向量、四元数、欧拉角等。本篇文章主要梳理一下这些表示方式及相互转换的方法。1...,pitch2/180*pi,roll2/180*pi); disp(R1);disp(R2);3.四元数(Quaternion)、旋转向量(Rotation Vector)、轴-角表示(Axis-Angle...
quat = quaternion(matrix) creates an N-by-1 quaternion array from an N-by-4 matrix, where each column becomes one part of the quaternion. example quat = quaternion(RV,"rotvec") creates an N-by-1 quaternion array from an N-by-3 matrix of rotation vectors, RV. Each row of RV repres...
This rotation format requires less computation than a rotation matrix. Common tasks for using quaternion include: Converting between quaternions, rotation matrices, and direction cosine matrices Performing quaternion math such as norm inverse and rotation ...
[1]旋转矩阵(rotation matrix) [2]旋转向量(rotation vector)/角轴(轴角)(axis angle) [3]欧拉角(euler angles) [4]四元数(quaternion) 主动旋转和被动旋转:主动旋转是指将向量或坐标系逆时针围绕旋转轴旋转,被动旋转是对坐标轴进行的逆时针旋转,相当于主动旋转的逆操作。
