电脑配置:Xavier-nx、ubuntu 18.04、ros melodic
激光雷达:Livox_Mid-360
结果展示:左边Mid360+Fast-lio感知建图,右边Ego-planner运动规划
1、读取雷达数据并显示
无人机避障——感知篇(采用Livox-Mid360激光雷达获取点云数据显示)-CSDN博客
看看雷达数据话题imu以及lidar两个话题
2、读取雷达数据并复现fast-lio

启动fast-lio,确保话题有输出
由于此处不需要建图,因此不打开rviz,launch文件如下修改:
<launch>
<!-- Launch file for Livox MID360 LiDAR --><arg name="rviz" default="true" /><rosparam command="load" file="$(find fast_lio)/config/mid360.yaml" /><param name="feature_extract_enable" type="bool" value="0"/><!-- 100HZ的bag point_filter_num建议设置为1; 10HZ的bag建议设置为2或3 --><param name="point_filter_num" type="int" value="3"/><param name="max_iteration" type="int" value="3" /><param name="filter_size_surf" type="double" value="0.5" /><param name="filter_size_map" type="double" value="0.5" /><param name="cube_side_length" type="double" value="1000" /><param name="runtime_pos_log_enable" type="bool" value="0" /><node pkg="fast_lio" type="fastlio_mapping" name="laserMapping" output="screen" /> <!-- <group if="$(arg rviz)"><node launch-prefix="nice" pkg="rviz" type="rviz" name="rviz" args="-d $(find fast_lio)/rviz_cfg/loam_livox.rviz" /></group> --></launch>
然后运行:
roslaunch fast_lio mapping_mid360.launch
