The principle is fine, as far as I can tell. The problem is likely in your actual code

yes, you'd need to do while(ros::ok()){ ... }. My understanding is, that the ros signal handler will make ros::ok() fail

That looks correct. As does your code. Maybe your 30khz update rate is overburdening rviz.

What does the pdf output look like if you run rosrun tf view_frames

Thanks for your answer. My problem seemingly was network related (roscore on a different machine than turtlebot). I had not set the environment variable ROS_IP correctly.

Did you solve this?

If I remember correctly, tf does interpolate.

In C++ you could create a tf2::BufferCore and use its setTransform method, then query it as usual. Maybe you can do something similar in python?

As NEngelhard says, 1mm is hard to achieve. Check out this paper, where the authors try to achieve maximum accuracy with laser scanners.

Accurate localization requires a precise map, so maybe try an approach as described in this paper

Stereo vision has measurement noise that grows quadratically with distance, therefore you won't get that good accuracy unless the distance to obstacles is always in a specific range.

Laser scanners have different inaccuracies. For example, from what I heard from users, SICK scanners are more accurate than Hokuyo, but this might be model dependent.

Fusion of different sensors usually improves results. But also using more than one of the same type may be advantageous. The guys in the first paper use two laser scanners, with opposite viewing direction, which helps a lot.

Works for me, thanks

As far as I know, roscpp installs a signal handler for Ctrl-C, which will do a clean exit. I'd guess rospy and other client libraries do the same.

I don't know whether that is possible, but you can definitely open the individual packages as projects.
