使用message_filters 进行时间同步的一般步骤如下: 1.创建一个 message_filters::Subscriber 对象来监听需要同步的话题,并指定消息类型。 2.创建一个 message_filters::Cache 对象来管理接收到的消息,并指定缓存的大小和策略(例如 ApproximateTime 或 ExactTime)。 3.创建一个回调函数,用于处理同步后的消息。该回调函...

1. message_filters.ApproximateTimeSynchronizer是什么 message_filters.ApproximateTimeSynchronizer 是ROS(Robot Operating System)中 message_filters 包提供的一个时间同步器,用于对来自不同话题(topics)的消息进行时间上的近似同步。这意味着它允许消息之间存在一定的时间偏差,但仍然可以认为它们是同步的。
