lidar_lane_detector

lidar_lane_detector is an open source ROS package for detecting road lines from raw 3D-LiDAR Sensor data.

• Extracting drivable area by using azimuth and channel.

• Distinguish lines from road markings.

• Detecting not only nearest lines but also other lines.

Nodes

lidar_lane_detector consists of only one node.

• lidar_lane_detector_node

Requirements

lidar_lane_detector requires following arguments.

• pcl_ros
• pcl_conversions
• Parsing raw 3D-LiDAR data by azimuth and channel (using OS1-64 LiDAR Sensor as default in this package)
  • If you are using Velodyne LiDAR Sensor, you can parsing raw 3D-LiDAR data by including lidar_lane_detector/include/lidar_lane_detector/point_xyzir.h and editing some code lines.
