Rotation matrix is the best choice here. The rotation matrix relating coordinate frames is easy to obtain and efficient to apply. Obtaining and applying a quaternion here would essentially require converting from rotation matrix and then converting back to rotation matrix.

Return the angle between this quaternion and the other along the shortest path.

I'm trying to implement a functionality that can convert an Euler angle into an Quaternion and back "YXZ"-convention using Eigen. Later this should be used to let the user give you Euler angles and I have a rotation quaternion and want to extract the angle of rotation about the Up axis (the yaw).

Euler to quaternion wiki Quaternion - Wikipedi . Die Quaternionen (Singular: die Quaternion, von lateinisch quaternio, -ionis f. Vierheit) sind ein Zahlbereich, der den Zahlbereich der reellen Zahlen erweitert - ähnlich den komplexen Zahlen und über diese hinaus.

quat = eul2quat(eul,sequence) converts a set of Euler angles into a quaternion. The Euler angles are specified in the axis rotation sequence, sequence.The default order for Euler angle rotations is "ZYX".

euler = euler_from_quaternion(quat, axes=’sxyz’) a, b, c = euler quat2 = quaternion_from_euler(a, b, c, axes=’sxyz’) x2, y2, z2, w2 = quat2. You will see that a, b, c is different than the input angles 1,2,3, but the quaternion representation is the same. Any ideas how to solve this problem with ROS? Reply

Quaternion to Euler angles conversion. The Euler angles can be obtained from the quaternions via the relations: [] = [(+) − (+) ((−)) (+) − (+)]Note, however, that the arctan and arcsin functions implemented in computer languages only produce results between −π/2 and π/2, and for three rotations between −π/2 and π/2 one does not obtain all possible orientations.

Added quaternion output but importing from tf1 for euler_from_quaternion seems wrong so not doing that yet. Also made count exit after n counts even if exceptions occurred, also printing time of lookup for exceptions #287; Fixed time query option, also changing message text to be more clear #287

Coordinate systems in ROS are always in 3D, and are right-handed, with X forward, Y left, and Z up. Points within a frame are represented using tf::Point, which is equivalent to the bullet type btVector3. The coordinates of a point p in a frame W are written as W p. Frame Poses Notation.
