The project is now owned by the OSRF and maintained by volunteers - currently Wolfgang (Lyft), Bo (Enway) and myself (Magazino). With the option to involve more people that are...

@imstevenpmwyca Yes, also cartographer_ros.

What you want to achieve is merging 2 pose graphs. In cartographer's map builder this would be possible by using `LoadState` two times for each of your files. But there's...

Work items are for example constraint searches and optimization steps. Following the tuning guide can help - e.g. if you decrease the constraint builder sampling ratio there will be less...

`-11` indicates a segmentation fault. Without further details this is all I can say regarding your brief description. On a side note, I would not expect too much stability from...

Each submap has its own coordinate frame origin that corresponds to the position of the first (accumulated) range scan data that was inserted into it. This means that global submap...

See https://github.com/cartographer-project/cartographer/issues/1675#issuecomment-710781559 for an update. We haven't discussed the open house format yet, but it might have a comeback.

Does your sensor data have the `frame_id`s set correctly? From the log it looks like something is empty and TF lookup fails because of that.

I would recommend to take a look which API functions are used in here: https://github.com/cartographer-project/cartographer_ros/blob/master/cartographer_ros/cartographer_ros/pbstream_to_ros_map_main.cc This tool reads a pbstream and creates an image from it. You can ignore the...

Your sensor data looks broken. `inf` values in odometry and negative laser readings don't make sense.
