为此,turtle1必须侦听正在发布turtle3位姿消息的话题,等待直到到期望坐标系的坐标变换准备就绪,然后执行其相应的操作。tf2_ros::MessageFilter类对于更轻松地实现这个功能非常有用。tf2_ros::MessageFilter类会订阅任何具有Header的ROS消息并对消息进行缓存,直到可以将其变换到目标坐标系。 19.1 设置 按照ROS wiki上的教...

tf2_ros::MessageFilter 是 ROS 2 中一个用于处理时间戳和坐标系变换的消息过滤器。它能够订阅带有 Header(包含时间戳和坐标系信息)的 ROS 消息,并将这些消息缓存起来,直到能够将它们从源坐标系变换到目标坐标系为止。这对于处理需要坐标系变换的传感器数据非常有用,例如相机或激光雷达数据。
