Indexing tool for rosbags #176

Closed takluyver closed 7 years ago

takluyver commented 7 years ago

I'd like to write a tool that can index rosbags, so I can quickly see details like how long each one was recorded for and which topics it contains.

Nanoseb commented 7 years ago

That is really nice! Small improvement: right now the oldest date is first when the reverse is more useful

takluyver commented 7 years ago

Thanks! I've reversed the sort order so the newest ones appear at the top.

https://github.com/ewerlopes/rosbag-sliding-windows-annotator not a finished thing, but they seem to be trying to do a similar thing to us

takluyver commented 7 years ago

There's some similarity, but I think it's different from what I'm trying to do. I can't quite get from the description what sort of thing that would be used for, but they seem to be talking about annotating data inside a rosbag using images also stored in the rosbag. This tool is to give us an overview of our different rosbag files.

This is now there and working nicely: https://github.com/Maritime-Robotics-Student-Society/sailing-robot/blob/master/utilities/index_recorded_data.py

Result:

The remaining change that I want to make is to add jinja2 to our docker image, because currently I have to launch docker and install it each time I want to use it.

OK, now if you don't have ROS, but do have docker, you can run the indexing script in a docker container like this:

./utilities/index_recorded_data.py --docker
