1. Prerequisites

1.1 Ubuntu and ROS. Tested on Ubuntu 18.04. ROS Melodic

1.2 Eigen

1.3 Ceres Solver

1.4 Opencv

2. Build on ROS

Clone the repository and catkin_make:

cd ~/catkin_ws/src
git clone https://github.com/ISEE-Technology/lidar-with-velocity
cd ../
catkin_make
source ~/catkin_ws/devel/setup.bash

3. Directly run

First download our dataset data and extract in /catkin_ws/ path.

replace the "DATASET_PATH" in config/config.yaml with your extracted dataset path, example: (notice the "/")

dataset_path: YOUR_CATKIN_WS_PATH/catkin_ws/data/

Then follow the commands blow :

roscore
rviz -d src/lidar-with-velocity/rviz_cfg/vis.rviz
rosrun lidar-with-velocity main_ros

there will be a Rviz window and a PCL Viewer window to show the results, press key "space" in the PCL Viewer window to process the next frame.
