1.3 Our hard-synchronized equipment

We open-source our handheld device, including CAD files, synchronization scheme, STM32 source code, wiring instructions, and sensor ROS driver. Access these resources at this repository: LIV_handhold.

1.4 Our associate dataset: FAST-LIVO2-Dataset

Our associate dataset FAST-LIVO2-Dataset used for evaluation is also available online.

1.5 Our LiDAR-camera calibration method

The FAST-Calib toolkit is recommended. Its output extrinsic parameters can be directly filled into the YAML file.

2. Prerequisited

2.1 Ubuntu and ROS

Ubuntu 18.04~20.04. ROS Installation.

2.2 PCL && Eigen && OpenCV

PCL>=1.8, Follow PCL Installation.

Eigen>=3.3.4, Follow Eigen Installation.

OpenCV>=4.2, Follow Opencv Installation.

2.3 Sophus

Sophus Installation for the non-templated/double-only version.

bashCopy
git clone https://github.com/strasdat/Sophus.git
cd Sophus
git checkout a621ff
mkdir build && cd build && cmake ..
make
sudo make install

2.4 Vikit

Vikit contains camera models, some math and interpolation functions that we need. Vikit is a catkin project, therefore, download it into your catkin workspace source folder.

bashCopy
# Different from the one used in fast-livo1
cd catkin_ws/src
git clone https://github.com/xuankuzcr/rpg_vikit.git 

3. Build

Clone the repository and catkin_make:

cd ~/catkin_ws/src
git clone https://github.com/hku-mars/FAST-LIVO2
cd ../
catkin_make
source ~/catkin_ws/devel/setup.bash

4. Run our examples

Download FAST-LIVO2-Dataset from Global-LVBA Section IV.
