VINS-GPS-Wheel

Visual-Inertial Odometry Coupled with Wheel Encoder and GNSS

This repo couples wheel encoder data and GPS data on the basis of VINS_Mono. The project is tested on KAIST dataset and is suitable for automatic driving scenario.

The wheel encoder data is tightly coupled, referred to the paper[1]. GPS fusion adopts loose coupling, and the fusion method is consistent with VINS-Fusion.

Detailed derivations can be found in: https://blog.csdn.net/ewtewtewrt/article/details/117249295 The method has tested in KAIST dataset (urban28-pankyo) video

Install

1. Prerequisites

1.1 Ubuntu and ROS

Ubuntu 16.04. ROS Kinetic. ROS Installation additional ROS pacakge

    sudo apt-get install ros-YOUR_DISTRO-cv-bridge ros-YOUR_DISTRO-tf ros-YOUR_DISTRO-message-filters ros-YOUR_DISTRO-image-transport

1.2 Dependencies

Follow Ceres Installation, remember to make install. (Our testing environment: Ubuntu 16.04, ROS Kinetic, OpenCV 3.1.0, Eigen 3.3.7)

2. Build VINS-Mono on ROS

Clone the repository and catkin_make:

    cd ~/catkin_ws/src
    git clone https://github.com/Wallong/VINS-GPS-Wheel.git
    cd ..
    catkin_make
    source ~/catkin_ws/devel/setup.bash

3. Dataset

The method is tested on KAIST dataset. https://irap.kaist.ac.kr/dataset/

4. Example

Open four terminals, launch the vins_estimator, rviz and pubish the data file respectively. Take urban28-pankyo for example

    roslaunch vins_estimator kaist.launch 
    rosrun multisensor_fusion multisensor_fusion_node (optional, for GPS)
    rosrun vins_estimator kaist_pub YOUR_PATH_TO_DATASET/KAIST/urban28/urban28-pankyo
    roslaunch vins_estimator vins_rviz.launch
