Detailed Description

Class that enables to define a feature or a set of features which are not implemented in ViSP as a specific class. It is indeed possible to create its own features, to use the corresponding interaction matrix, and to compute an error between the current and the desired feature. Moreover the created features can be mixed with features already implemented.

The following example shows how to use the vpGenericFeature class to create and use the feature where Z corresponds to the depth of a point whose 2D coordinates in the camera frame are $ x $ and $ y $ . The interaction matrix corresponding to this feature is

$L = \left[\begin{array}{cccccc} 0 & 0 & -1/Z & -y & x & 0 \end{array}\right]$

.

#include <visp3/core/vpGenericFeature.h>
#include <visp3/vs/vpServo.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  vpServo task; // Visual servoing task
 
  //First we have to define the desired feature log(Z*) corresponding to the desired point.
  double xd = 0; //The x coordinate of the desired point.
  double yd = 0; //The y coordinate of the desired point.
  double Zd = 1; //The depth of the desired point.
  vpGenericFeature logZd(1); //The dimension of the feature is 1.
  logZd.set_s( log(Zd) );
 
  //Then we have to define the current feature log(Z) corresponding to the current point.
  double x = 1; //The x coordinate of the current point.
  double y = 1; //The y coordinate of the current point.
  double Z = 2; //The depth of the current point.
  vpGenericFeature logZ(1); //The dimension of the feature is 1.
  logZ.set_s( log(Z) );
 
  // Set eye-in-hand control law.
  // The computed velocities will be expressed in the camera frame
  task.setServo(vpServo::EYEINHAND_CAMERA);
  // Interaction matrix is computed with the current visual features sd
  task.setInteractionMatrixType(vpServo::CURRENT);
 
  // Add the point feature to the task
  task.addFeature(logZ, logZd);
 
  // Control loop
  for ( ; ; ) {
    // The new parameters x, y and Z must be computed here.
 
    // Update the current point visual feature
    logZ.set_s( log(Z) ) ;
 
    // We have to compute the interaction matrix corresponding to the feature.
    vpMatrix LlogZ(1,6) ;
    LlogZ[0][0] = LlogZ[0][1] = LlogZ[0][5] = 0 ;
    LlogZ[0][2] = -1/Z;
    LlogZ[0][3] = -y;
    LlogZ[0][4] =  x;
    logZ.setInteractionMatrix(LlogZ) ;
 
    // compute the control law
    vpColVector v = task.computeControlLaw(); // camera velocity
  }
  return 0;
}

The second example shows how to create and use a feature whose specificity is to have a desired feature fixed to zero. It is the case for the feature $log( \frac{Z}{Z^*})$ .

#include <visp3/core/vpGenericFeature.h>
#include <visp3/vs/vpServo.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  vpServo task; // Visual servoing task
 
  //First we have to define the desired feature log(Z*) corresponding to the desired point.
  double xd = 0; //The x coordinate of the desired point.
  double yd = 0; //The y coordinate of the desired point.
  double Zd = 1; //The depth of the desired point.
 
  //Then we have to define the current feature log(Z) corresponding to the current point.
  double x = 1; //The x coordinate of the current point.
  double y = 1; //The y coordinate of the current point.
  double Z = 2; //The depth of the current point.
  vpGenericFeature logZ(1); //The dimension of the feature is 1.
  logZ.set_s( log(Z/Zd) );
 
  // Set eye-in-hand control law.
  // The computed velocities will be expressed in the camera frame
  task.setServo(vpServo::EYEINHAND_CAMERA);
  // Interaction matrix is computed with the current visual features sd
  task.setInteractionMatrixType(vpServo::CURRENT);
 
  // Add the point feature to the task
  task.addFeature(logZ);
 
  // Control loop
  for ( ; ; ) {
    // The new parameters x, y and Z must be computed here.
 
    // Update the current point visual feature
    logZ.set_s( log(Z/Zd) ) ;
 
    // We have to compute the interaction matrix corresponding to the feature.
    vpMatrix LlogZ(1,6) ;
    LlogZ[0][0] = LlogZ[0][1] = LlogZ[0][5] = 0 ;
    LlogZ[0][2] = -1/Z;
    LlogZ[0][3] = -y;
    LlogZ[0][4] =  x;
    logZ.setInteractionMatrix(LlogZ) ;
 
    // compute the control law
    vpColVector v = task.computeControlLaw(); // camera velocity
  }
  return 0;
}

If the feature needs to be use with other features, the example servoSimuPoint2DhalfCamVelocity2.cpp shows how to do it.

Examples: servoSimuPoint2DhalfCamVelocity2.cpp, and servoSimuSphere.cpp.

◆ error() [1/2]

vpColVector vpGenericFeature::error	(	const vpBasicFeature &	s_star,
		unsigned int	select = `FEATURE_ALL`
	)

virtual

Compute the error between the current and the desired visual features from a subset of the possible features.

Exceptions

if errorHasBeenInitialized is true (that is if vpGenericFeature::setError have been used) then s_star is useless. In that since the error HAS TO BE recomputed at each iteration errorHasBeenInitialized is set to errHasToBeUpdated if vpGenericFeature::serError is not used in the loop then an exception is thrown

obviously if vpGenericFeature::setError is not used then s_star is considered and this warning is meaningless.

Parameters

s_star : Desired visual feature.

select

: The error can be computed for a selection of a subset of the possible features.

To compute the error for all the features use vpBasicFeature::FEATURE_ALL. In that case the error vector column vector whose dimension is equal to the number of features.
To compute the error for only one of the component feature you have to say which one you want to take into account. If it is the first one set select to vpBasicFeature::FEATURE_LINE[0], if it is the second one set select to vpBasicFeature::FEATURE_LINE[1], and so on. In that case the error vector is a 1 dimension column vector.
To compute the error for only two of the component feature you have to say which ones you want to take into account. If it is the first one and the second one set select to vpBasicFeature::FEATURE_LINE[0] | vpBasicFeature::FEATURE_LINE[1]. In that case the error vector is a 2 dimension column vector.

Returns: The error between the current and the desired visual feature.

The code below shows how to use this method to manipulate the two visual features over three:

// Creation of the current feature s
vpGenericFeature s(3);
s.set_s(0, 0, 0);
 
// Creation of the desired feature s*
vpGenericFeature s_star(3);
s_star.set_s(1, 1, 1);
 
// Here you have to compute the interaction matrix L
s.setInteractionMatrix(L);
 
// Compute the error vector (s-s*) for the two first features
s.error(s_star, vpBasicFeature::FEATURE_LINE[0] | vpBasicFeature::FEATURE_LINE[1]);

◆ error() [2/2]

vpColVector vpGenericFeature::error ( unsigned int select = FEATURE_ALL )

Compute the error between the current and the desired visual features from a subset of the possible features. But in this case the desired feature is considered as set to 0.

Parameters

select

: The error can be computed for a selection of a subset of the possible features.

To compute the error for all the features use vpBasicFeature::FEATURE_ALL. In that case the error vector column vector whose dimension is equal to the number of features.
To compute the error for only one of the component feature you have to say which one you want to take into account. If it is the first one set select to vpBasicFeature::FEATURE_LINE[0], if it is the second one set select to vpBasicFeature::FEATURE_LINE[1], and so on. In that case the error vector is a 1 dimension column vector.
To compute the error for only two of the component feature you have to say which ones you want to take into account. If it is the first one and the second one set select to vpBasicFeature::FEATURE_LINE[0] | vpBasicFeature::FEATURE_LINE[1]. In that case the error vector is a 2 dimension column vector.

Returns: The error between the current and the desired visual feature which is automatically set to zero.

The code below shows how to use this method to manipulate the two visual features over three:

// Creation of the current feature s
vpGenericFeature s(3);
s.set_s(0, 0, 0);
 
// Here you have to compute the interaction matrix L
s.setInteractionMatrix(L);
 
// Compute the error vector (s-s*) for the two first features
s.error(vpBasicFeature::FEATURE_LINE[0] | vpBasicFeature::FEATURE_LINE[1]);
