Laser Scan Matcher for ROS

This repo is the implementation of Point-to-Line Iterative Closest Point (PL-ICP) algorithm proposed by Censi [1]. The original code can be found in [2]. However, there are some bugs about ROS tf transform in the original code. I fixed the bugs and added the mapping module following the programming habits in open karto library [3].

How to use on Ubuntu?

1. This package has been tested well in Ubuntu 16.04 with ROS Kinetic.
2. If you want to use it, you must install csm first:
    $ sudo apt-get install ros-kinetic-csm
3. Clone the repo to your workspace and complie it
    $ cd ~/catkin_ws/src/
    $ git clone https://github.com/nkuwenjian/laser_scan_matcher.git
    $ cd ../
    $ catkin_make
    $ source devel/setup.bash
4. Run offline rosbag
    $ roslaunch laser_scan_matcher demo.launch
    $ rosbag play <rosbagfile> --clock
