mrpt::graphslam::deciders::CRangeScanOps< GRAPH_T > Class Template Reference

Detailed Description

template<class GRAPH_T = typename mrpt::graphs::CNetworkOfPoses2DInf>
class mrpt::graphslam::deciders::CRangeScanOps< GRAPH_T >

Class for keeping together all the RangeScanner-related functions.

Deciders that make use of either 2DRangeScans (laser generated observations) or 3DRangeScans (RGBD-cameras) can inherit from this class in case they want to use the underlying methods

The configuration parameters of the current decider class are listed below. These parameters are parsed from an external .ini configuration file from their respective section. If an optional parameter is not found a default value is used instead. If a mandatory/required parameter is not found a runtime error is raised. For a sample configuration file see $mrpt/share/mrpt/config_files/graphslam-engine/laser_odometry.ini (Modify $mrpt according to the path of your mrpt source directory).

• conversion_sensor_label
  • Default value : "KINECT_TO_2D_SCAN"
  • Required : FALSE
  • Description : Applicable only when dealing with 3DRangeScans. Used for converting 3DRangeScan to 2DRangesScan so that they are visualized on the 2D surface
• conversion_angle_sup
  • Default value : 10
  • Required : FALSE
  • Description : Applicable only when dealing with 3DRangeScans. Used for converting 3DRangeScan to 2DRangesScan so that they are visualized on the 2D surface
• conversion_angle_inf
  • Default value : 10
  • Required : FALSE
  • Description : Applicable only when dealing with 3DRangeScans. Used for converting 3DRangeScan to 2DRangesScan so that they are visualized on the 2D surface
• conversion_oversampling_ratio
  • Default value : 1.1
  • Required : FALSE
  • Description : Applicable only when dealing with 3DRangeScans. Used for converting 3DRangeScan to 2DRangesScan so that they are visualized on the 2D surface

Note

Class contains an instance of the mrpt::slam::CICP class and it parses the configuration parameters of the latter from the "ICP" section. Refer to mrpt::slam::CICP documentation for its list of configuration parameters

convert3DTo2DRangeScan()

template<class GRAPH_T >

bool mrpt::graphslam::deciders::CRangeScanOps< GRAPH_T >::convert3DTo2DRangeScan ( mrpt::obs::CObservation3DRangeScan::Ptr &  scan3D_in, mrpt::obs::CObservation2DRangeScan::Ptr *  scan2D_out  )

protected

Wrapper around the CObservation3DRangeScan::convertTo2DScan corresponding method.

Returns

True if operation was successful, false otherwise

protected

Reduce the size of the given CPointsMap by keeping one out of "keep_point_every" points.

Note

If low_lim is set then the PointsMap will contain at least low_lim measurements, regardless of keep_point_every value. Set low_lim to 0 if no lower limit is to be specified

protected

Align the 2D range scans provided and fill the potential edge that can transform the one into the other.

User can optionally ask that additional information be returned in a TReturnInfo struct

protected

Align the 3D range scans provided and find the potential edge that can transform the one into the other.

Fills the 2D part (rel_edge) of the 3D constraint between the scans, since we are interested in computing the 2D alignment. User can optionally ask that additional information be returned in a TReturnInfo struct
