Typedef 转载：四国一一、前言首先，为什么要进行数据的转换？举个例子，在ROS中，我们通过订阅Kinect的RGB图像topic就可以获取到图像数据，但当我们要对这些图像进行处理的时候，我们需要用到专门的图像处理库，比如OpenCV．因此，我们需要用到ROS提供的package，cv_brige，将ROS格式的数据转换为OpenCV适用使用的速腾16线激光雷达，需使用pointcloud_to_laserscan转换为/scan用作cartographer 2D建图测试，但在运行相关节点并订阅/scan消息后 pointcloud_to_laserscanを普通にcloneするとROS2のものになってしまうので、対応方法をメモ過去のブランチを取ってくるだけなので、知見というほどでもないが・・・。 pointcloud_to_laserscan . This is useful for making devices like the Kinect appear like a laser scanner for 2D-based algorithms (e. Share. 1 在ROS2 (Robot Operating System) 中，`pointcloud_to_laserscan`是一个转换节点，它主要用于将点云数据（通常是由传感器产生的点云消息）转换为激光扫描数据（laser scan），这是一种常见于机器人导航中的数据格式。 README Velodyne ROS 2 pointcloud to laserscan converter .
