I am not sure where I went wrong with the installtion of the Mapping software from this guide https://github.com/Livox-SDK/livox_mapping Everything seems to have been install correctly but when I launch the rivz viwer with the lidar (Mid 40) it looks the same as with on the Livox vi...
First, set a path to save the point cloud in the livox_mapping.launch file. Modify the extrinsic parameters in livox_mapping_case.cpp if your coordinates are different from ours. Modify the lidar_delta_time in livox_mapping_case.cpp if your LiDAR data frequency is not 100Hz.; 3.3.1 On...

To demonstrate the great potential of Livox LiDARs in 3D mapping, we showcase how they can be integrated into a drone to accomplish mapping tasks. As a test, we mapped the 3km-long Huizhou Bay Bridge, located in Huizhou, Guangdong, China.
livox_high_precision_mapping是一种利用Livox激光雷达和APX-15惯性导航系统进行高精度地图制作的技术。Livox激光雷达具有高分辨率、高精度和高帧率的特点,可以快速获取周围环境的三维点云数据。APX-15惯性导航系统则可以提供准确的位置和姿态信息。在livox_high_precision_mapping中,Livox激光雷达通过扫描周围环境,获取大量...
