IMU频率的GPS-IMU 融合算法

本软件包提供了一种基于ESKF的GPS-IMU生成IMU频率里程计的融合算法,使用本软件包时,请注明软件包出处。

详细参考知乎:https://zhuanlan.zhihu.com/p/627857398

1. 安装:

1.1 安装依赖

# 必须安装以下依赖
#1. pcl 
#2. GeographicLib
sudo apt-get install libpcl-dev libgeographic-dev

1.2 编译package

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
git clone https://gitee.com/dawanzi98/gnss_imu_odom_at_imu_rate.git
cd ../..
catkin_make

2 运行

包内提供了三个launch文件: kitti的数据集可以从https://github.com/leo6862/ins_eskf_kitti 下载

1. kitti.launch: 适用kitti数据集
2. mulran.launch: 适用mulran数据集

3 配置

位于包内./config文件夹下

imu_sub_topic: /kitti/oxts/imu/extract # imu话题
gnss_sub_topic: /kitti/oxts/gps/fix # GNSS 话题
cloud_topic: /rslidar_points #点云话题,不开启点云显示节点,该配置无效
# 0 输出gnss频率的里程计,1 输出 imu频率的里程计
hz_mode: 1 #0 for gps rate ; 1 for imu rate
