Laser scan tools for ROS


Laser scan processing tools. The meta-package contains:

  • laser_ortho_projector: calculates orthogonal projections of LaserScan messages

    • License: BSD-3-Clause
  • laser_scan_matcher: an incremental laser scan matcher, using Andrea Censi's Canonical Scan Matcher (CSM) implementation [1].

    • License: BSD-3-Clause, LGPL
    • Note: CSM is LGPL-3.0 licensed and depends on either GSL, which is GPL-3.0 or eigen, which is MPL-2.0, depending on the version of CSM.
  • laser_scan_sparsifier: takes in a LaserScan message and sparsifies it

    • License: BSD-3-Clause
  • laser_scan_splitter: takes in a LaserScan message and splits it into a number of other LaserScan messages

    • License: BSD-3-Clause
  • ncd_parser: reads in .alog data files from the New College Dataset [2] and broadcasts scan and odometry messages to ROS.

    • License: BSD-3-Clause
  • polar_scan_matcher: used to produce a pose estimate for a robot when no odometry is available.

    • License: GPL-2.0
  • scan_to_cloud_converter: converts LaserScan to PointCloud messages.

    • License: BSD-3-Clause



apt-get install ros-%ROS_DISTRO%-scan-tools

apt-get install ros-indigo-scan-tools        (Indigo)

From source

Following is an example with ROS Indigo.

  1. Create a catkin workspace and navigate to its source directory (e.g. ~/catkin_ws/src).

  2. In your Catkin workspace, download source and build with the following commands.

cd ~/catkin_ws
wstool init src
wstool merge -t src
rosdep install --from-paths src --ignore-src --rosdistro indigo -r -y
catkin_make                (or any build commands available in ROS, e.g. `catkin build`)
source devel/setup.bash
