Detailed Description

Functionality computation for 2D rotation/translation/scale non-symmetric invariant moment feature. Computes the interaction matrix associated with vpMomentCInvariant.

The interaction matrix for the moment feature can be deduced from [48], equations (9). To do so, one must derive them and obtain a combination of interaction matrices by using (1). It allows to compute the interaction matrix for $ c_i, i \in [1..10] $.

These interaction matrices may be selected afterwards by calling vpFeatureMomentCInvariant::interaction(). The selection by the vpFeatureMomentCInvariant::selectCi method for $ L_{c_i} $. For example, to select $ L_{c_1} $ you should input vpFeatureMomentCInvariant::selectC1() into ViSP's selector. Special matrices for features $ S_x $ and $ S_y $ are selected by vpFeatureMomentCInvariant::selectSx() and vpFeatureMomentCInvariant::selectSy() respectively. Special matrices for features $ P_x $ and $ P_y $ are selected by vpFeatureMomentCInvariant::selectPx() and vpFeatureMomentCInvariant::selectPy() respectively.

These features are often used in moment-based visual servoing to control the two out-of-plane rotations.

Be careful about the nature of your object when selecting the right features. Use $ L_{S_{x}} $ and $ L_{S_{y}} $ when you're dealing with a symmetric object all other features otherwise.

Minimum vpMomentObject order needed to compute this feature: 6. This is the highest order required by classic features.

This feature depends on:

An example of how to use vpFeatureMomentCInvariant in a complete visual servoing example is given in vpFeatureMomentCommon.

◆ duplicate()

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

Returns
The corresponding feature.

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  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.
