这里使用了tf2_ros::MessageFilter来处理障碍物观测数据。主要是因为tf2_ros::MessageFilter可以保证只有在传感器的fram和global_fram的tf关系有效的情况下再执行数据的回调函数。在障碍物数据叠加到costmap层的过程中需要将障碍物数据转换到全局坐标系下。所以需要保证其tf转换是有效的才进行数据处理。

请注意我所说的是“如果你要自己创建发布者”。由于缺少订阅者连接回调,ROS 1中许多被广泛使用的包的ROS 2端口都是不可使用的,例如:message_filters、image_transport、image_proc、depth_image_proc…… 相关问题可以浏览这篇帖子:订阅匹配中的ROS 2的发布者回调 (https://...
