Detailed Description

A camera sensor that reports locations of objects instead of rendering a scene.

This camera finds models in the sensor's vicinity, and transmits information about the models on the sensor's topic.

gazebo::sensors::LogicalCameraSensor::LogicalCameraSensor ( )

Constructor.

virtual gazebo::sensors::LogicalCameraSensor::~LogicalCameraSensor ( )
virtual

Destructor.

Member Function Documentation

double gazebo::sensors::LogicalCameraSensor::AspectRatio ( ) const

Get the aspect ratio, which is the width divided by height of the near or far planes.

Returns
The frustum's aspect ratio.
double gazebo::sensors::LogicalCameraSensor::Far ( ) const

Get the far distance.

This is the distance from the frustum's vertex to the farthest plane.

Returns
Far distance.
virtual void gazebo::sensors::LogicalCameraSensor::Fini ( )
protectedvirtual

Finalize the sensor.

Reimplemented from gazebo::sensors::Sensor.

virtual std::string gazebo::sensors::LogicalCameraSensor::GetTopic ( ) const
virtual

Returns the topic name as set in SDF.

Returns
Topic name.
Deprecated:
See Topic() function.

Reimplemented from gazebo::sensors::Sensor.

ignition::math::Angle gazebo::sensors::LogicalCameraSensor::HorizontalFOV ( ) const

Get the horizontal field of view.

The field of view is the angle between the frustum's vertex and the edges of the near or far plane. This value represents the horizontal angle.

Returns
The field of view.
msgs::LogicalCameraImage gazebo::sensors::LogicalCameraSensor::Image ( ) const

Get the latest image.

An image is an instance of msgs::LogicalCameraImage, which contains a list of detected models.

Returns
List of detected models.
virtual void gazebo::sensors::LogicalCameraSensor::Init ( )
virtual

Initialize the sensor.

Reimplemented from gazebo::sensors::Sensor.

virtual bool gazebo::sensors::LogicalCameraSensor::IsActive ( ) const
virtual

Returns true if sensor generation is active.

Returns
True if active, false if not.

Reimplemented from gazebo::sensors::Sensor.

virtual void gazebo::sensors::LogicalCameraSensor::Load ( const std::string &  _worldName,
sdf::ElementPtr  _sdf 
)
virtual

Load the sensor with SDF parameters.

Parameters
[in]_sdfSDF Sensor parameters.
[in]_worldNameName of world to load from.

Reimplemented from gazebo::sensors::Sensor.

virtual void gazebo::sensors::LogicalCameraSensor::Load ( const std::string &  _worldName)
virtual

Load the sensor with default parameters.

Parameters
[in]_worldNameName of world to load from.

Reimplemented from gazebo::sensors::Sensor.

double gazebo::sensors::LogicalCameraSensor::Near ( ) const

Get the near distance.

This is the distance from the frustum's vertex to the closest plane.

Returns
Near distance.
virtual bool gazebo::sensors::LogicalCameraSensor::UpdateImpl ( const bool  )
protectedvirtual

This gets overwritten by derived sensor types.

This function is called during Sensor::Update. And in turn, Sensor::Update is called by SensorManager::Update

Parameters
[in]_forceTrue if update is forced, false if not
Returns
True if the sensor was updated.

Reimplemented from gazebo::sensors::Sensor.
