Detailed Description

Functionality computation for basic moment feature. Computes the interaction matrix associated with vpMomentBasic.

The interaction matrix for the basic moment feature is defined in [44], equation (13). This vpFeatureMoment, as well as it's corresponding moment primitive is double-indexed. The interaction matrix $ L_{m_{ij}} $ is obtained by calling vpFeatureMomentBasic::interaction (i,j) and is associated to $ m_{ij} $ obtained by vpMomentBasic::get (i,j). vpFeatureMomentBasic computes interaction matrices all interaction matrices up to vpMomentObject::getOrder()-1.

Attention
The maximum order reached by vpFeatureMomentBasic is NOT the maximum order of the vpMomentObject, it is one unit smaller. For example if you define your vpMomentObject up to order n then vpFeatureMomentBasic will be able to compute interaction matrices up to order n-1 that is $ L_{m_{ij}} $ with $ i+j<=n-1 $.

You can see an example of vpFeatureMomentBasic by looking at the documentation of the vpFeatureMoment class.

void vpFeatureMoment::display ( const vpCameraParameters &  cam,
const vpImage< unsigned char > &  I,
const vpColor &  color = vpColor::green,
unsigned int  thickness = 1 
) const
virtualinherited

Not implemented since visual representation of a moment doesn't often make sense.

Implements vpBasicFeature.

Definition at line 114 of file vpFeatureMoment.cpp.

◆ display() [2/2]

Definition at line 128 of file vpFeatureMoment.cpp.

◆ duplicate()

vpBasicFeature * vpFeatureMoment::duplicate ( ) const
virtualinherited

Duplicates the feature into a vpGenericFeature harbouring the same properties. The resulting feature is of vpMomentGenericFeature type.

Returns
The corresponding feature.

  • 1 << j + 1 << k + 1 << l.

◆ update()

void vpFeatureMoment::update ( double  A_,
double  B_,
double  C_

Updates the interaction matrices with the image plane the camera is facing. The plane must be in the format: $ \frac{1}{Z}=Ax+By+C $ . The moment primitives MUST be updated before calling this function.

This method also computes the interaction matrix. Therefore, you must call vpFeatureMoment::update before calling vpFeatureMoment::interaction.

Attention
The behaviour of this method is not the same as vpMoment::update which only acknowledges the new object. This method also computes the interaction matrices.
Parameters
A_: A coefficient of the plane.
B_: B coefficient of the plane.
C_: C coefficient of the plane.
Examples:
mbot-apriltag-ibvs.cpp, and servoBebop2.cpp.
