<!-- Configuration of customized pointclouds:
Parameter "custom_pointclouds" lists all customized pointclouds to be published. Each pointcloud is given by its name and configured by the following parameters:
"<name_of_custom_pointcloud>" type="string" value="list of key-value-pairs"
The list of key-value-pairs defines the pointcloud properties. List of supported key-value-pairs for customized pointclouds:
Parameter "coordinateNotation" is an enum to configure pointcloud coordinates:
coordinateNotation=0: cartesian (default, pointcloud has fields x,y,z,i), identical to customized with fields=x,y,z,i
coordinateNotation=1: polar (pointcloud has fields azimuth,elevation,r,i), identical to customized with fields=azimuth,elevation,range,i
coordinateNotation=2: both cartesian and polar (pointcloud has fields x,y,z,azimuth,elevation,r,i), identical to customized with fields=x,y,z,azimuth,elevation,range,i
coordinateNotation=3: customized pointcloud fields, i.e. the pointcloud has fields configured by parameter "fields"
Parameter "updateMethod" is an enum to configure fullframe pointclouds versus segmented pointcloud:
updateMethod=0: fullframe pointcloud (default)
updateMethod=1: segmented pointcloud
Parameter "fields" defines the fields of the pointcloud for coordinateNotation == 3 (customized pointcloud fields), e.g.
fields=x,y,z,i: cartesian pointcloud
fields=range,azimuth,elevation: polar pointcloud
or any other combination of x,y,z,i,range,azimuth,elevation,t,ts,ring,layer,echo,reflector
These fields have the following meaning:
field "x": cartesian x coordinate in meter in ROS coordinates (4 byte, float32)
field "y": cartesian y coordinate in meter in ROS coordinates (4 byte, float32)
field "z": cartesian z coordinate in meter in ROS coordinates (4 byte, float32)
field "i": intensity (4 byte, float32)
field "range": polar coordinate range in meter (4 byte, float32)
field "azimuth": polar coordinate azimuth in radians (4 byte, float32)
field "elevation": polar coordinate elevation in radians (4 byte, float32)
field "t": time offset in nano seconds relative to the header timestamp in the point cloud (4 byte, uint32), used by rtabmap for deskewing
field "ts": time offset in seconds relative to the header timestamp (4 byte, float32)
field "ring": layer id (1 byte, int8), identical to field "layer"
field "layer": layer (group) index (4 byte, int32), 0 <= layer < 16 for multiScan (16 layer), 0 for picoScan (1 layer)
field "echo": echo index (4 byte, int32)
field "reflector": optional reflector bit (1 byte, uint8), 0 or 1, default: 0
Parameter "echos" defines which echos are included in the pointcloud, e.g.
echos=0,1,2: all echos
echos=2: last echo
or any other combination of 0,1,2
Parameter "layers" defines which layers are included in the pointcloud, e.g
layers=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 for all layers
layers=6 for the 0 degree layer
or any other combination of 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16
Note: layer ids enumerate from 1 up to 16.
Parameter "reflectors" filters the points by the reflector bit, i.e.
reflectors=0,1 for points with reflector bit set or not set
reflectors=0 for points with reflector bit not set
reflectors=1 for points with reflector bit set
Parameter "infringed" defines filters the points by infringement, i.e.
infringed=0,1 for points with infringement bit set or not set
infringed=0 for points with infringement bit not set
infringed=1 for points with infringement bit set
Parameter "infringed" is currently not supported (reserved for future use)
Optional parameter "rangeFilter" configures how invalid measurements are filtered in the customized pointcloud.
rangeFilter=<range_min>,<range_max>,<filter_flag>
The range (distance) of invalid scan points is 0 and can be filtered, i.e. removed from the pointcloud or set to 0, FLT_MAX or NAN.
If the range (distance) of a scan point is less than <range_min> or greater than <range_max>, this point is filtered depending on <filter_flag>:
<filter_flag> = 0: RANGE_FILTER_DEACTIVATED, do not apply range filter (default)
<filter_flag> = 1: RANGE_FILTER_DROP, drop point, if range is not within [range_min, range_max]
<filter_flag> = 2: RANGE_FILTER_TO_ZERO, set range to 0, if range is not within [range_min, range_max]
<filter_flag> = 3: RANGE_FILTER_TO_RANGE_MAX, set range to range_max, if range is not within [range_min, range_max]
<filter_flag> = 4: RANGE_FILTER_TO_FLT_MAX, set range to FLT_MAX, if range is not within [range_min, range_max]
<filter_flag> = 5: RANGE_FILTER_TO_NAN set range to NAN, if range is not within [range_min, range_max]
Note: Using range_filter_handling 4 or 5 requires handling of FLT_MAX and NAN values in an application.
The working range of a picoScan is specified by 0.05 m up to 120 m. Example to drop invalid measurements:
rangeFilter=0.05,120,1
Note: "structured" pointclouds contain all scan points (valid and invalid), i.e. these pointclouds are not filtered. Each scan point has a fixed offset in a structured pointcloud.
"unstructured" pointclouds contain all valid measurements, i.e. these pointclouds are filtered and contain valid scan points only. Azimuth and elevation of the n-th scan point is not constant.
Parameter "topic" defines the ros topic, e.g. topic=/cloud_fullframe for cartesian fullframe pointclouds
Parameter "frameid" defines the ros frame of the pointcloud, e.g. frameid=world, frameid=map or frameid=base_link
Parameter "publish" activates or deactivates the pointcloud, e.g. publish=1 to generate and publish, or publish=0 to deactivate that pointcloud

On ROS-1 and ROS-2, sick_scan_xd publishes TF messsages to map a given base frame (i.e. base coordinates system) to the lidar frame (i.e. lidar coordinates system) and vice versa.
The default base frame id is "map" (which is the default frame in rviz).
The default 6D pose is (x,y,z,roll,pitch,yaw) = (0,0,0,0,0,0) defined by position (x,y,z) in meter and (roll,pitch,yaw) in radians.
This 6D pose (x,y,z,roll,pitch,yaw) is the transform T[base,lidar] with parent "base" and child "lidar".
For lidars mounted on a carrier, the lidar pose T[base,lidar] and base frame can be configured in this launchfile using the following parameter.
The lidar frame id given by parameter "frame_id" resp. "publish_frame_id".
Note that the transform is specified using (x,y,z,roll,pitch,yaw). In contrast, the ROS static_transform_publisher uses commandline arguments in order (x,y,z,yaw,pitch,roll).
