To compile your code I have to provide a template argument (Scalar) when constructing a Quaternion, e.g.. Returns a quaternion representing a rotation between the two arbitrary vectors a and b. Common base class for compact rotation representations. Compared to other representations like Euler angles or 3x3 matrices, quaternions offer the following advantages: The following two typedefs are provided for convenience: Default constructor leaving the quaternion uninitialized. _Scalar. . How is this smodin.io AI-generated Chinese passage? I have no idea about this, but I find ros tf::getYaw() also can achieve "Quaternion to Euler" (because I just need yaw angle). 2022.11.16 18 0. // intersection of the two planes. // Note that this algorithm comes from the optimization by hand. #include <Eigen/Geometry> Template Parameters This class represents a quaternion that is a convenient representation of orientations and rotations of objects in three dimensions.
