Detailed Description

Sensor with one or more rays.

This sensor cast rays into the world, tests for intersections, and reports the range to the nearest object. It is used by ranging sensor models (e.g., sonars and scanning laser range finders).

Constructor & Destructor Documentation

gazebo::sensors::RaySensor::RaySensor ( )

Constructor.

virtual gazebo::sensors::RaySensor::~RaySensor ( )

virtual

Destructor.

Member Function Documentation

ignition::math::Angle gazebo::sensors::RaySensor::AngleMax ( ) const

Get the maximum angle.

Returns: the maximum angle object

ignition::math::Angle gazebo::sensors::RaySensor::AngleMin ( ) const

Get the minimum angle.

Returns: The minimum angle object

virtual void gazebo::sensors::RaySensor::Fini ( )

protectedvirtual

Finalize the sensor.

Reimplemented from gazebo::sensors::Sensor.

math::Angle gazebo::sensors::RaySensor::GetAngleMax ( ) const

Get the maximum angle.

Returns: the maximum angle object

Deprecated:: See AngleMax() function that returns an ignition::math::Angle object.

math::Angle gazebo::sensors::RaySensor::GetAngleMin ( ) const

Get the minimum angle.

Returns: The minimum angle object

Deprecated:: See AngleMin() function that returns an ignition::math::Angle object.

double gazebo::sensors::RaySensor::GetAngleResolution ( ) const

Get the angle in radians between each range.

Returns: Resolution of the angle

int gazebo::sensors::RaySensor::GetFiducial ( unsigned int _index )

Get detected fiducial value for a ray.

Warning: If you are accessing all the ray data in a loop it's possible that the Ray will update in the middle of your access loop. This means some data will come from one scan, and some from another scan. You can solve this problem by using SetActive(false) <your accessor="" loop>=""> SetActive(true).

Parameters

[in] _index Index value of specific ray

Returns: Fiducial value

physics::MultiRayShapePtr gazebo::sensors::RaySensor::GetLaserShape ( ) const

inline

Returns a pointer to the internal physics::MultiRayShape.

Returns: Pointer to ray shape

double gazebo::sensors::RaySensor::GetRange ( unsigned int _index )

Get detected range for a ray.

Warning: If you are accessing all the ray data in a loop it's possible that the Ray will update in the middle of your access loop. This means some data will come from one scan, and some from another scan. You can solve this problem by using SetActive(false) <your accessor="" loop>=""> SetActive(true).

Parameters

[in] _index Index of specific ray

Get all the ranges.

Parameters

_ranges A vector that will contain all the range data

int gazebo::sensors::RaySensor::GetRayCount ( ) const

Get the ray count.

Returns: The number of rays

double gazebo::sensors::RaySensor::GetRetro ( unsigned int _index )

Get detected retro (intensity) value for a ray.

Warning: If you are accessing all the ray data in a loop it's possible that the Ray will update in the middle of your access loop. This means some data will come from one scan, and some from another scan. You can solve this problem by using SetActive(false) <your accessor="" loop>=""> SetActive(true).

Parameters

[in] _index Index of specific ray

Returns: Retro (intensity) value for ray

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