概要
在ROS中将点云(PointCloud)转换为激光扫描(LaserScan)是一个常见的任务,尤其是在某些机器人系统中,激光雷达数据被用于导航和避障,但传感器输出的是点云数据。这种转换可以通过 pointcloud_to_laserscan 包实现,该包提供了一个节点,可以将接收到的PointCloud2消息转换成LaserScan消息。
安装pointcloud_to_laserscan
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
git clone -b lunar-devel https://github.com/ros-perception/pointcloud_to_laserscan.git
cd ..
catkin_make
修改配置
