◆ ChSensor()

CH_SENSOR_API chrono::sensor::ChSensor::ChSensor	(	std::shared_ptr< chrono::ChBody >	parent,
		float	updateRate,
		chrono::ChFrame< double >	offsetPose
	)

Constructor for the base sensor class.

updateRate	Rate at which the sensor should update.
offsetPose	Relative position and orientation of the sensor with respect to its parent object.

Member Function Documentation

◆ GetCollectionWindow()

float chrono::sensor::ChSensor::GetCollectionWindow ( ) const

inline

Get the sensor data collection window (seconds)

Returns: The duration of simulation time over which the sensor generates its data

◆ GetFilterList()

std::list<std::shared_ptr<ChFilter> > chrono::sensor::ChSensor::GetFilterList ( ) const

inline

Get the sensor's list of filters.

Returns: An immutable list of filters that are used to generate and augment the sensor's data

◆ GetLag()

float chrono::sensor::ChSensor::GetLag ( ) const

inline

Get the sensor lag (seconds)

Returns: The lag of the sensor

◆ GetMostRecentBuffer()

template<class UserBufferType >

UserBufferType chrono::sensor::ChSensor::GetMostRecentBuffer ( )

Get the last filter in the list that matches the template type.

Returns: A shared pointer to a ChSensorBuffer of the templated type.

◆ GetName()

std::string chrono::sensor::ChSensor::GetName ( ) const

inline

Get the name of the sensor.

Returns: The string name of the sensor

◆ GetNumLaunches()

unsigned int chrono::sensor::ChSensor::GetNumLaunches ( )

inline

Get the number of times the sensor has been updated.

Returns: The number of times an update for the sensor has been started

◆ GetOffsetPose()

ChFrame<double> chrono::sensor::ChSensor::GetOffsetPose ( )

inline

Get the sensor's relative position and orientation.

Returns: The frame that specifies the offset pose

◆ GetParent()

std::shared_ptr<ChBody> chrono::sensor::ChSensor::GetParent ( ) const

inline

Get the object to which the sensor is attached.

Returns: A shared pointer to the body on which the sensor is attached

◆ GetUpdateRate()

float chrono::sensor::ChSensor::GetUpdateRate ( ) const

inline

Get the sensor update rate (Hz)

Returns: The update rate in Hz

◆ LockFilterList()

void chrono::sensor::ChSensor::LockFilterList ( )

inline

Gives ability to lock the filter list to prevent race conditions.

This is called automatically when the sensor is added to the ChSensor manager. This is needed to prevent changing of filters while a worker thread is processing the filters. WARNING: this operation cannot be undone.

◆ PushFilter()

CH_SENSOR_API void chrono::sensor::ChSensor::PushFilter ( std::shared_ptr< ChFilter > filter )

Add a filter to the sensor.

Parameters

filter A filter that should be added to the filter list if the filter list is not yet locked. If the filter list has been locked (i.e. the sensor has started generating data) the new filter will be ignored.

◆ SetCollectionWindow()

CH_SENSOR_API void chrono::sensor::ChSensor::SetCollectionWindow ( float t )

Set the collection window.

Parameters

t	The collection time of the sensor

◆ SetLag()

CH_SENSOR_API void chrono::sensor::ChSensor::SetLag ( float t )

Set the lag parameter.

Parameters

t	The lag time

◆ SetName()

void chrono::sensor::ChSensor::SetName ( std::string name )

inline

Set the sensor's name.

Parameters

name	Name of the sensor -> not used for any internal critical mechanisms

◆ SetOffsetPose()

void chrono::sensor::ChSensor::SetOffsetPose ( chrono::ChFrame< double > pose )

inline

Set the sensor's relative position and orientation.

Parameters

pose	The relative position and orientation with respect to the parent body

◆ SetUpdateRate()

void chrono::sensor::ChSensor::SetUpdateRate ( float updateRate )

inline

Set the sensor update rate (Hz)

Parameters

updateRate Desired update rate in Hz

Member Data Documentation

◆ m_collection_window

float chrono::sensor::ChSensor::m_collection_window

protected

time over which data is collected.

(lag+shutter = time from when data collection is started to when it is available to the user)
