#cplusplus#hap#mid_360#ros#ros2 Livox ROS Driver 2 connects your Livox LiDARs like HAP and Mid360 to ROS (Noetic) or ROS2 (Foxy/Humble/Jazzy) on matching Ubuntu versions. Clone the repo in a workspace/src folder, build Livox-SDK2, then run ./build.sh with your ROS version, and launch with roslaunch or ros2 launch files from launch_ROS1/ROS2 folders—edit JSON configs for IP, ports, frequency (up to 100Hz), and formats. This lets you quickly test and visualize point clouds in RViz for robotics development, saving time on setup and debugging. https://github.com/Livox-SDK/livox_ros_driver2

宇宙是无限的吗？ 观测数据显示宇宙呈现平坦状态，但其真实大小和超出可观测范围的整体形状可能永远无法确定。科学家指出，如同地球表面具有可测量的尺寸，如果地球膨胀，其尺寸会随时间增加。然而，宇宙的真实性质，包括其是否无限，以及超出可观测范围的形状，仍然是未解之谜。目前的技术手段无法确定宇宙的全局几何结构，其真实尺寸和形状可能永远无法被人类完全认知。SciTechDaily 🏷#Universe#Cosmic#Geometry#Observations 📢频道👥群组📝投稿
