Member Function Documentation

virtual bool ParticleClassifierParticleFilter::clear ( )

inlinevirtual

Clears any previous setup.

Returns: returns true if the filter was cleared successfully, false otherwise

Reimplemented from ParticleFilter< Particle, VectorFloat >.

Definition at line 127 of file ParticleClassifierParticleFilter.h.

virtual bool ParticleClassifierParticleFilter::postFilterUpdate ( VectorFloat & data )

inlinevirtual

This function lets you define a custom post filter update if needed.

Parameters

SENSOR_DATA &data: a reference to the sensor data input to the main filter function.

Returns: returns true if the update was completed successfully, false otherwise

Reimplemented from ParticleFilter< Particle, VectorFloat >.

Definition at line 75 of file ParticleClassifierParticleFilter.h.

virtual bool ParticleClassifierParticleFilter::predict ( Particle & p )

inlinevirtual

This is the main predict function. This function must be implemented in your derived class.

Parameters

PARTICLE &p: the current particle that should be passed through your prediction code

Returns: returns true if the particle prediction was updated successfully, false otherwise

Reimplemented from ParticleFilter< Particle, VectorFloat >.

Definition at line 80 of file ParticleClassifierParticleFilter.h.

virtual bool ParticleClassifierParticleFilter::preFilterUpdate ( VectorFloat & data )

inlinevirtual

This function lets you define a custom pre filter update if needed.

Parameters

SENSOR_DATA &data: a reference to the sensor data input to the main filter function.

Returns: returns true if the update was completed successfully, false otherwise

Reimplemented from ParticleFilter< Particle, VectorFloat >.

Definition at line 58 of file ParticleClassifierParticleFilter.h.

virtual bool ParticleClassifierParticleFilter::update	(	Particle &	p,
		VectorFloat &	data
	)

inlinevirtual

This is the main update function in which the weight of the particle should be computed, based on the particles current estimated state and the latest sensor data.

This function must be implemented in your derived class.

Parameters

PARTICLE	&p: the current particle
SENSOR_DATA	&data: the current sensor data

Returns: returns true if the particle update was updated successfully, false otherwise

Reimplemented from ParticleFilter< Particle, VectorFloat >.

Definition at line 98 of file ParticleClassifierParticleFilter.h.
