1. Prerequisites

  1. ubuntu 16.04 + ROS Kinetic

  2. Eigen3

2. Usage

    cd catkin_ws/src
    git clone https://github.com/MegviiRobot/OdomLaserCalibraTool
    cd ..
    catkin_make
    source devel/setup.bash
    roslaunch example.launch

INPUT:

A rosbag includes laser scan and odometer data(left & right wheels' velocity). Please check the topic name with launch file.

*Note that we use rostopic type geometry_msgs::Vector3Stamped to record odometer's raw data, for other types please modify the code.

OUTPUT:

Extrinsic parameters between LiDAR and odomter(x, y, yaw), intrinsic paramters of odomter(left & right wheels' radius, track between two wheels) and related uncertainty analysis.
