void las3D_PointCloud::accumulate_cloud ( pcl::PointCloud< pcl::PointXYZ > * pc_in )

Function to accumulate PointCloud. Receives the pointcloud with the transformed laser scan and accumulates it on the class variable pc_accumulated.

Parameters:

pc_in

pointcloud to transform

Definition at line 39 of file laser3D_pointcloud.cpp.

const boost::numeric::ublas::matrix< double > & las3D_PointCloud::getUnitVectors_	(	double	angle_min,
		double	angle_max,
		double	angle_increment,
		unsigned int	length
	)			`[protected]`

Internal protected representation of getUnitVectors.

This function should not be used by external users, however, it is left protected so that test code can evaluate it appropriately.

int las3D_PointCloud::las3D_transformLaserScanToPointCloud	(	const std::string &	target_frame,
		const sensor_msgs::LaserScan &	scan_in,
		sensor_msgs::PointCloud2 &	cloud_out,
		tf::Transformer &	tf,
		double	range_cutoff = `-1.0`,
		int	channel_options = `channel_option::Default`
	)			`[inline]`

Transform a sensor_msgs::LaserScan into a sensor_msgs::PointCloud2 in target frame using the scan time stamps. Transform a single laser scan from a linear array into a 3D point cloud, accounting for movement of the laser over the course of the scan. In order for this transform to be meaningful at a single point in time, the target_frame must be a fixed reference frame.

Parameters:

	target_frame	The frame of the resulting point cloud
	scan_in	The input laser scan
	cloud_out	The output point cloud
	tf	a tf::Transformer object to use to perform the transform
	range_cutoff	An additional range cutoff which can be applied which is more limiting than max_range in the scan.
	channel_option	An OR'd set of channels to include. Options include: channel_option::Default, channel_option::Intensity, channel_option::Index, channel_option::Distance, channel_option::Timestamp.

		double	range_cutoff = `-1.0`,
		int	channel_options = `channel_option::Default`
	)			`[inline]`

Transform a sensor_msgs::LaserScan into a sensor_msgs::PointCloud2 in target frame using the external information of the external shaft angle. Transform a single laser scan from a linear array into a 3D point cloud, accounting for movement of the laser over the course of the scan. In order for this transform to be meaningful at a single point in time, the target_frame must be a fixed reference frame.

Parameters:

	target_frame	The frame of the resulting point cloud
	scan_in	The input laser scan
	cloud_out	The output point cloud
	tf	a tf::Transformer object to use to perform the transform
	state_start	The external shaft angle mensage at the start of the scan
	state_end	The external shaft angle mensage at the end of the scan
	range_cutoff	An additional range cutoff which can be applied which is more limiting than max_range in the scan.
	channel_option	An OR'd set of channels to include. Options include: channel_option::Default, channel_option::Intensity, channel_option::Index, channel_option::Distance, channel_option::Timestamp.
