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:

vpRxyzVector rxyz;
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 finally 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()
{
  vpRxyzVector rxyz;
 
  // 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
  vpRotationMatrix R(rxyz);
 
  // 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;
}

◆ insert()

void vpArray2D< double >::insert	(	const vpArray2D< double > &	A,
		const vpArray2D< double > &	B,
		vpArray2D< double > &	C,
		unsigned int	r,
		unsigned int	c
	)

Parameters

A	: Main array.
B	: Array to insert.
C	: Result array.
r	: Index of the row where to insert array B.
c	: Index of the column where to insert array B.

Warning: Throw exception if the sizes of the arrays do not allow the insertion.

◆ operator*()

vpColVector operator*	(	const double &	x,

	)

◆ operator==() [1/2]

bool operator== ( const vpArray2D< double > & A ) const

◆ operator==() [2/2]

bool operator== ( const vpArray2D< float > & A ) const

◆ vpGEMM()

void vpGEMM	(	const vpArray2D< double > &	A,
		const vpArray2D< double > &	B,
		const double &	alpha,
		const vpArray2D< double > &	C,
		const double &	beta,
		vpArray2D< double > &	D,
		const unsigned int &	ops = `0`
	)

For example, to compute D = alpha*A^T*B^T+beta*C we need to call :

vpGEMM(A, B, alpha, C, beta, D, VP_GEMM_A_T + VP_GEMM_B_T);

vpArray2D< double >::vpGEMM

void vpGEMM(const vpArray2D< double > &A, const vpArray2D< double > &B, const double &alpha, const vpArray2D< double > &C, const double &beta, vpArray2D< double > &D, const unsigned int &ops=0)

Definition vpGEMM.h:388

If C is not used, vpGEMM must be called using an empty array null. Thus to compute D = alpha*A^T*B, we have to call:

vpGEMM(A, B, alpha, null, 0, D, VP_GEMM_B_T);

Exceptions

vpException::incorrectMatrixSizeError if the sizes of the matrices do not allow the operations.

Parameters

A	: An array that could be a vpMatrix.
B	: An array that could be a vpMatrix.
alpha	: A scalar.
C	: An array that could be a vpMatrix.
beta	: A scalar.
D	: The resulting array that could be a vpMatrix.
ops	: A scalar describing operation applied on the matrices. Possible values are the one defined in vpGEMMmethod(): VP_GEMM_A_T, VP_GEMM_B_T, VP_GEMM_C_T.

◆ vpGEMMmethod

enum vpGEMMmethod

Operations are :

VP_GEMM_A_T to use the transpose matrix of A instead of the matrix A
VP_GEMM_B_T to use the transpose matrix of B instead of the matrix B
VP_GEMM_C_T to use the transpose matrix of C instead of the matrix C
