Use tf2_ros::MessageFilter to sync images and transforms by timestamp #15

Would this be something tf2_ros::MessageFilter could be used for?

Would this also be a good way to synchronize images and CameraInfo messages?

gavanderhoorn commented 4 years ago

As CameraInfo does have a Header, it could potentially be used, but ppl typically would use image_transport to match frames with their corresponding CameraInfo messages (via a CameraSubscriber).

这tf2_ros::MessageFilter会被用于吗？
