Description
The lslidar_c16 package is a linux ROS driver for lslidar c16.
The package is tested on Ubuntu 16.04/18.04 with ROS kinetic/melodic.
Compling
This is a Catkin package. Make sure the package is on ROS_PACKAGE_PATH after cloning the package to your workspace. And the normal procedure for compling a catkin package will work.
cd your_work_space
catkin_make
Example Usage
lslidar_c16_decoder
Parameters
lidar_ip (string, default: 192.168.1.200)
By default, the IP address of the device is 192.168.1.200.
frame_id (string, default: laser_link)
The frame ID entry for the sent messages.
Published Topics
lslidar_point_cloud
Each message corresponds to a lslidar packet sent by the device through the Ethernet.
lslidar_c16_decoder
Parameters
min_range (double, 0.3)
max_range (double, 200.0)
Points outside this range will be removed.
frequency (frequency, 10.0)
Note that the driver does not change the frequency of the sensor.
publish_point_cloud (bool, true)
If set to true, the decoder will additionally send out a local point cloud consisting of the points in each revolution.
Published Topics
lslidar_sweep (lslidar_c16_msgs/LslidarChSweep)
The message arranges the points within each sweep based on its scan index and azimuth.
lslidar_pointclou_c16 (sensor_msgs/PointCloud2)
This is only published when the publish_point_cloud is set to true in the launch file.
Node
roslaunch lslidar_c16_decoder lslidar_c16.launch --screen
Note that this launch file launches both the driver and the decoder, which is the only launch file needed to be used.
