Gets the raw image data from the sensor.

Returns
The pointer to the image data array.
unsigned int gazebo::sensors::CameraSensor::GetImageHeight ( ) const

Gets the height of the image in pixels.

Returns
The image height in pixels.
unsigned int gazebo::sensors::CameraSensor::GetImageWidth ( ) const

Gets the width of the image in pixels.

Returns
The image width in pixels.
virtual std::string gazebo::sensors::CameraSensor::GetTopic ( ) const
virtual

Returns
Topic name
Todo:
to be implemented

Reimplemented from gazebo::sensors::Sensor.

virtual void gazebo::sensors::CameraSensor::Init ( )
virtual

Initialize the camera.

Reimplemented from gazebo::sensors::Sensor.

virtual bool gazebo::sensors::CameraSensor::IsActive ( )
virtual

Returns true if sensor generation is active.

Returns
True if active, false if not.

Reimplemented from gazebo::sensors::Sensor.

virtual void gazebo::sensors::CameraSensor::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::CameraSensor::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.

bool gazebo::sensors::CameraSensor::SaveFrame ( const std::string &  _filename)

Saves the image to the disk.

Parameters
[in]_filenameThe name of the file to be saved.
Returns
True if successful, false if unsuccessful.
virtual bool gazebo::sensors::CameraSensor::UpdateImpl ( 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.
