Member Function Documentation

◆ computeError()

virtual dg::Vector& dynamicgraph::sot::FeatureVisualPoint::computeError ( dg::Vector &  res,
int  time 
)
virtual

Compute the error between the desired feature and the current value of the feature measured or deduced from the robot state.

[out] res: The error will be set into res.
[in] time: The time at which the error is computed.
Returns
The vector res with the appropriate value.

Implements dynamicgraph::sot::FeatureAbstract.

◆ computeJacobian()

virtual dg::Matrix& dynamicgraph::sot::FeatureVisualPoint::computeJacobian ( dg::Matrix &  res,
int  time 
)
virtual

Compute the Jacobian of the error according the robot state.

[out] res: The matrix in which the error will be written.
Returns
The matrix res with the appropriate values.

Implements dynamicgraph::sot::FeatureAbstract.

◆ DECLARE_REFERENCE_FUNCTIONS()

virtual

◆ getClassName()

virtual const std::string& dynamicgraph::sot::FeatureVisualPoint::getClassName ( void  ) const
inlinevirtual

Returns the name class.

Reimplemented from dynamicgraph::sot::FeatureAbstract.

◆ getDimension()

virtual unsigned int& dynamicgraph::sot::FeatureVisualPoint::getDimension ( unsigned int &  res,
int  time 
)
virtual

Verbose method.

res: The integer in which the dimension will be return.
time: The time at which the feature should be considered.
Returns
Dimension of the feature.
Note
Be careful with features changing their dimension according to time.

Implements dynamicgraph::sot::FeatureAbstract.
