Detailed Description

Implementation of a pose vector and operations on poses.

The vpPose class implements a complete representation of every rigid motion in the euclidian space.

The vpPose class is derived from vpArray2D<double>.

The pose is composed of a translation and a rotation minimaly represented by a 6 dimension pose vector as:

$^{a}{\bf r}_b = [^{a}{\bf t}_{b},\theta {\bf u}]^\top \in R^6$

where $^{a}{\bf r}_b$ is the pose from frame $ a $ to frame $ b $ , with $^{a}{\bf t}_{b}$ being the translation vector between these frames along the x,y,z axis and $\theta \bf u$ , the axis-angle representation of the rotation $^{a}\bf{R}_{b}$ between these frames.

Translations are expressed in meters, while the angles in the $\theta {\bf u}$ axis-angle representation are expressed in radians.

To know more about the $\theta \bf u$ rotation representation, see vpThetaUVector documentation.

The following code shows how to initialize a pose vector:

#include <visp3/core/vpPoseVector.h>
int main()
{
  vpPoseVector pose;
  pose[0] = 0.1;    // tx
  pose[1] = 0.2;    // ty
  pose[2] = 0.3;    // tz
  pose[3] = M_PI;   // tux
  pose[4] = M_PI_2; // tux
  pose[5] = M_PI_4; // tuz
  std::cout << "pose vector:\n" << pose << std::endl;
}

It produces the following printings:

pose vector:
1
2
3
141592654
570796327
7853981634

The same initialization could be achieved this way:

#include <visp3/core/vpPoseVector.h>
int main()
{
  vpTranslationVector t;
  vpThetaUVector tu;
  t << 0.1, 0.2, 0.3;
  tu << M_PI, M_PI_2, M_PI_4;
  vpPoseVector pose(t, tu);
}

If ViSP is build with c++11 suport, you could also initialize the vector using:

#include <visp3/core/vpPoseVector.h>
int main()
{
  vpTranslationVector t;
  vpThetaUVector tu;
#if (VISP_CXX_STANDARD >= VISP_CXX_STANDARD_11)
  t = { 0.1, 0.2, 0.3 };
  tu = { M_PI, M_PI_2, M_PI_4 };
#endif
  vpPoseVector pose(t, tu);
}

Pretty print a pose vector. The data are tabulated. The common widths before and after the decimal point are set with respect to the parameter maxlen.
