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 [26], 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 ordrer 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.

virtualinherited

Duplicates the feature into a vpGenericFeature harbouring the same properties. The resulting feature is of vpMomentGenericFeature type. While it still can compute interaction matrices and has acces to it's moment primitive, it has lost all precise information about its precise type and therefore cannot be used in a feature database.

Returns: The corresponding feature.

Parameters

select : Feature selector.

Returns: The corresponding interaction matrix.

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.

void vpFeatureMoment::update	(	double	A_,

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.
