Detailed Description

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

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

$R_{zyx}(\varphi,\theta,\psi) = R_z(\varphi) \; R_y(\theta) \; R_x(\psi)$

with

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

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

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

The vpRzyxVector 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:

vpRzyxVector rzyx;
rzyx[0] = M_PI_4;
rzyx[1] = M_PI_2;
rzyx[2] = M_PI;

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

rzyx << 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)
  rzyx = {M_PI_4, M_PI_2, M_PI};
#endif

To get the values [rad] use:

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

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

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