VINS-Fusion for RGB-D

This is a specific verision of VINS-Fusion( based on https://github.com/HKUST-Aerial-Robotics/VINS-Fusion ) that supports RGB-D sensors. Some codes we reference the project VINS-RGBD (https://github.com/STAR-Center/VINS-RGBD)

一种可支持RGB-D传感器的VINS-Fusion算法

1、可支持单目、双目、RGB-D与IMU的融合定位
RGBD在视觉跟踪时将特征点的参数化与双目相机一致,可实现静止状态的初始化。

2、使用RGB-D时可实现基于八叉树的稠密建图
实时生成局部三维稠密地图,地图可在图优化后进行修正,可保存关键帧的位姿图信息(带有三维稠密点云地图的), 可读取位姿图信息载入先前构建的三维地图,可通过载入地图的方式实现多地图融合。

3、支持栅格图导入
栅格图的生成在support_files中,主要利用保存的位姿图实现。

实验中使用realsense d435i传感器,相关参数参考realsense_depth_imu_config.yaml。

1. Prerequisites

1.1 Ubuntu and ROS

Ubuntu 64-bit 16.04 or 18.04. ROS Kinetic or Melodic. ROS Installation

1.2. OpenCV

OpenCV 2.4.8

1.3. Ceres Solver

Follow Ceres Installation.

1.4. PCL

PCL 1.7

2. Build

    cd ~/catkin_ws/src
    git clone https://github.com/ManiiXu/VINS-Fusion.git
    cd ../
    catkin_make
    source ~/catkin_ws/devel/setup.bash

3. Example

3.1 运行局部定位

rosrun vins vins_node /home/xuduo/catkin_ws/src/VINS-Fusion/config/realsense/realsense_depth_imu_config.yaml

3.2 运行全局定位与稠密建图

rosrun loop_fusion loop_fusion_node /home/xuduo/catkin_ws/src/VINS-Fusion/config/realsense/realsense_depth_imu_config.yaml

3.3 录制bag文件

rosbag record /camera/imu /camera/color/image_raw /camera/aligned_depth_to_color/image_raw

仅供学习。
