[人工智能]VINS定位和即时八叉树建图步骤

在工作空间catkin_ws终端运行

1、先source一下，以免报错（注：后面每一步都可以source一下）

source ~/catkin_ws/devel/setup.bash

2、打开D435i相机

roslaunch realsense2_camera rs_camera_vins.launch

3、按ctrl+shift+t，打开另一个终端

运行vins和打开rviz

roslaunch vins vins_rviz.launch

4、运行ros节点

rosrun vins vins_node ~/catkin_ws/src/VINSFusion/config/realsense_d435i/realsense_stereo_imu_config.yaml

5、运行即时建图代码

rosrun lyq pcl_octomap3

注：

修改realsense_strtro_imu_config.yaml时使用imu+双目标定结果中的camchain-imucam-imu_stereo.yaml中的数据

body_T_cam0和 body_T_cam1中的data数据来源为cam0:T_cam_imu:和cam1:T_cam_imu:

即为imu的数据data。
