Hi community.

I have some trouble in stereo camera data logging that some old data pushed after newer one. Figure of timestamp

The way to save this data is like this: prepare empty list and push new data in each subscription and then save this list as csv. How can I prevent this problem in a real situation?

Thank you.

Try out the time sequencer message filter http://wiki.ros.org/message_filters#T... . It looks like you want a buffer size to handle 3 seconds of messages.
