Usage

lslidar_n301_driver

Parameters

  • device_ip (string, default: 192.168.1.222)
    • By default, the IP address of the device is 192.168.1.222.
  • frame_id (string, default: lslidar)
    • The frame ID entry for the sent messages.

Published Topics

  • lslidar_packets (lslidar_n301_msgs/Lslidarn301Packet)
    • Each message corresponds to a lslidar packet sent by the device through the Ethernet.

lslidar_n301_decoder

Parameters

  • min_range (double, 0.3)
  • max_range (double, 100.0)
    • Points outside this range will be removed.
  • frequency (frequency, 20.0)
    • Note that the driver does not change the frequency of the sensor. If set to true, the decoder will additionally send out a local point cloud consisting of the points in each revolution.
  • publish_point_cloud (bool, false)
    • 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_n301_msgs/LslidarN301Sweep)
    • The message arranges the points within each sweep based on its scan index and azimuth.
  • lslidar_point_cloud (sensor_msgs/PointCloud2)
    • This is only published when the publish_point_cloud is set to true in the launch file.

Tutorial

  • Running following commmand to launch lslidar n301 drive

roslauch lslidar_n301_decoder lslidar_n301_decoder_nodelet.launch

Note that this launch file launches both the driver and the decoder, which is the only launch file needed to be used.
