Detailed Description

Functionality computation for in-plane rotation moment feature $ \alpha $: computes the interaction matrix associated with vpMomentAlpha.

The interaction matrix for the feature can be deduced from [45].

This class computes the interaction matrix associated to $ \alpha = \frac{1}{2} arctan(\frac{2\mu_{11}}{\mu_{20}-\mu_{02}}) $ moment primitive.

The interaction matrix for the feature has the following form:

\[{ \left[ \begin {array}{c} {\frac {\mu_{{1,1}}{\it DA}\,A}{d}}+{\frac { \left( {\it DA}\,\mu_{{0,2}}+1/2\,d-1/2\,{{\it DA}}^{2} \right) B}{d} }\\ \noalign{\medskip}{\frac { \left( {\it DA}\,\mu_{{0,2}}-1/2\,d-1/2 \,{{\it DA}}^{2} \right) A}{d}}-{\frac {B\mu_{{1,1}}{\it DA}}{d}} \\ \noalign{\medskip}Bw_{{x}}-Aw_{{y}}\\ \noalign{\medskip}{\frac { \beta\, \left( \mu_{{1,2}} \left( \mu_{{2,0}}-\mu_{{0,2}} \right) +\mu _{{1,1}} \left( \mu_{{0,3}}-\mu_{{2,1}} \right) \right) +\gamma\,x_{{ g}} \left( \mu_{{0,2}} \left( \mu_{{2,0}}-\mu_{{0,2}} \right) -2\,{\mu _{{1,1}}}^{2} \right) +\gamma\,y_{{g}}\mu_{{1,1}} \left( \mu_{{2,0}}+ \mu_{{0,2}} \right) }{d}}\\ \noalign{\medskip}{\frac {\beta\, \left( \mu_{{2,1}} \left( \mu_{{0,2}}-\mu_{{2,0}} \right) +\mu_{{1,1}} \left( \mu_{{3,0}}-\mu_{{1,2}} \right) \right) +\gamma\,x_{{g}}\mu_{ {1,1}} \left( \mu_{{2,0}}+\mu_{{0,2}} \right) +\gamma\,y_{{g}} \left( \mu_{{2,0}} \left( \mu_{{0,2}}-\mu_{{2,0}} \right) -2\,{\mu_{{1,1}}}^{ 2} \right) }{d}}\\ \noalign{\medskip}-1\end {array} \right] }^t \]

with ${\it DA} = \mu_{{2,0}}-\mu_{{0,2}}$ and ${\it d} = DA^2+4{\mu_{1,1}}^2$.

  • In the discrete case: $beta = 4$, $gamma = 2$.
  • In the dense case: $beta = 5$, $gamma = 1$.

The interaction matrix computed is single-dimension (no selection possible) and can be obtained by calling vpFeatureMomentAlpha::interaction().

This feature is often used in moment-based visual servoing to control the planar rotation parameter.

Minimum vpMomentObject order needed to compute this feature: 4.

This feature depends on:

vpFeatureMomentAlpha::vpFeatureMomentAlpha ( vpMomentDatabase &  data_base,

Initializes the feature with information about the database of moment primitives, the object plane and feature database.

Parameters
data_base: Moment database. The database of moment primitives (first parameter) is mandatory. It is used to access different moment values later used to compute the final matrix.
A_: Plane coefficient in a $ A \times x+B \times y + C = \frac{1}{Z} $ plane.
B_: Plane coefficient in a $ A \times x+B \times y + C = \frac{1}{Z} $ plane.
C_: Plane coefficient in a $ A \times x+B \times y + C = \frac{1}{Z} $ plane.

const vpImage< unsigned char > &  I,
const vpColor &  color = vpColor::green,
unsigned int  thickness = 1

◆ duplicate()

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

Returns
The corresponding feature.

virtualinherited

Retrieves the interaction matrix. No computation is done.

Parameters
select: Feature selector.

There is no rule about the format of the feature selector. It may be different for different features. For example, for vpFeatureMomentBasic or vpFeatureMomentCentered features, select may refer to the $ (i,j) $ couple in the $ j \times order + i $ format, but for vpFeatureMomentCInvariant the selector allows to select couples $ (i,j,k,l...) $ in the following format: 1 << i

  • 1 << j + 1 << k + 1 << l.

◆ update()

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

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.
