2023/08/15: Repository for HeLiPR file player now available.

We're diligently working to upload the dataset link. This paper is under-reviewed, but readers can be found our paper in arxiv. If user wants to utilize the undistortion or accumulation of pointcloud from .bin file, please visite the HeLiPR-Pointcloud-Toolbox.

1. Pre-requisites

Before utilizing the file player, it's crucial to have both the novatel-gps-msgs and livox custom messages. Ensure you install these drivers:

Novatel GPS Driver Installation:

Replace 'version' with your appropriate ROS version (e.g., melodic, noetic).

sudo apt-get install ros-'version'-novatel-gps-driver

Livox ROS Driver Installation:

Visit the official Livox SDK repository on GitHub:

Livox ROS Driver on GitHub

Ensure that both drivers are correctly installed for seamless operation of the file player.

2. Obtain Dependent Package (Defined msg)

To set up the necessary workspace and clone the file player repository:

$ mkdir ~/catkin_ws
$ cd ~/catkin_ws
$ mkdir src
$ cd src
$ git clone https://github.com/rpmsnu/helipr_file_player.git
$ cd ~/catkin_ws/src/helipr_file_player

3. Build the Workspace

Compile and build the workspace:

$ cd ~/catkin_ws
$ catkin_make

4. Execute the File Player

To run the file player, make sure to source your workspace:

$ source devel/setup.bash
$ roslaunch file_player file_player.launch

5. Load Data Files and Play

Here's a step-by-step guide:

1. Click the 'Load' button.
2. Navigate and select the desired dataset folder.
3. Hit the player button to commence publishing data as ROS messages.
4. Use the 'Stop skip' button to skip intervals when the vehicle remains stationary. This feature enhances the user experience by focusing on significant data.
5. The loop button ensures that the data resumes playback from the beginning once completed.
