Hi,

Does anyone know how I can detect from Google's Cartographer when a map is complete, when and area has been previously visited and lastly when a map is complete?

Thanks

Mark

Are you wanting to know how to tell by physically looking at the output? Or in code by looking for some "cartographer has finished"-style flag?

I want to determine when the map is complete. In code is how I want to achieve this

I don't feel like this is a real answer, but one option might be to try reading the ROS info output - Cartographer seems to output predictable strings when it adds a new submap and finishes it's mapping process. Wouldn't have a clue where to begin though sorry.
