Detailed Description

Implementation of a rotation vector as $R(x,y,z)$ Euler angle minimal representation.

Class that consider the case of the Euler $(\varphi,\theta,\psi)$ angle using the x-y-z convention, where $(\varphi,\theta,\psi)$ are respectively the rotation angles around the $x$, $y$ and $z$ axis.

\[R_{xyz}(\varphi,\theta,\psi) = R_x(\varphi) \; R_y(\theta) \; R_z(\psi)\]

with

\[R_{x}(\varphi) = \left( \begin{array}{ccc} 1 & 0 & 0 \\ 0 &\cos \varphi & -\sin\varphi \\ 0 &\sin \varphi & \cos\varphi \\ \end{array} \right) \; R_{y}(\theta) = \left( \begin{array}{ccc} \cos \theta & 0 & \sin\theta\\ 0 & 1 & 0 \\ -\sin\theta & 0 &\cos \theta \end{array} \right) \; R_{z}(\psi) = \left( \begin{array}{ccc} \cos \psi & -\sin\psi & 0\\ \sin\psi &\cos \psi& 0 \\ 0 & 0 & 1 \end{array} \right)\]

The rotation matrix corresponding to the x-y-z convention is given by:

\[ R_{xyz}(\varphi,\theta,\psi) = \left( \begin{array}{ccc} \cos\theta \cos\psi & -\cos\theta \sin\psi & \sin\theta \\ \sin\varphi \sin\theta \cos\psi + \cos\varphi\sin\psi & -\sin\varphi \sin\theta \sin\psi +\cos\varphi\cos\psi & -\sin\varphi \cos\theta \\ -\cos\varphi \sin\theta \cos\psi + \sin\varphi\sin\psi & \cos\varphi \sin\theta \sin\psi +\sin\varphi\cos\psi & \cos\varphi \cos\theta \end{array} \right) \]

The vpRxyzVector class is derived from vpRotationVector.

From the implementation point of view, it is nothing more than an array of three doubles with values in [rad].

You can set values [rad] accessing each element:

rxyz[0] = M_PI_4;
rxyz[1] = M_PI_2;
rxyz[2] = M_PI;

You can also initialize the vector using operator<<(double):

rxyz << M_PI_4, M_PI_2, M_PI;

Or you can also initialize the vector from a list of doubles if ViSP is build with c++11 enabled:

#if (VISP_CXX_STANDARD >= VISP_CXX_STANDARD_11)
rxyz = {M_PI_4, M_PI_2, M_PI};
#endif

To get the values [rad] use:

double rx = rxyz[0];
double ry = rxyz[1];
double rz = rxyz[2];

The code below shows first how to initialize this representation of Euler angles, than how to contruct a rotation matrix from a vpRxyzVector and finaly how to extract the vpRxyzVector Euler angles from the build rotation matrix.

#include <iostream>
#include <visp3/core/vpMath.h>
#include <visp3/core/vpRotationMatrix.h>
#include <visp3/core/vpRxyzVector.h>
int main()
{
// Initialise the Euler angles
rxyz[0] = vpMath::rad( 45.f); // phi angle in rad around x axis
rxyz[1] = vpMath::rad(-30.f); // theta angle in rad around y axis
rxyz[2] = vpMath::rad( 90.f); // psi angle in rad around z axis
// Construct a rotation matrix from the Euler angles
// Extract the Euler angles around x,y,z axis from a rotation matrix
rxyz.buildFrom(R);
// Print the extracted Euler angles. Values are the same than the
// one used for initialization
std::cout << rxyz;
// Since the rotation vector is 3 values column vector, the
// transpose operation produce a row vector.
vpRowVector rxyz_t = rxyz.t();
// Print the transpose row vector
std::cout << rxyz_t << std::endl;
}
