Sorry it will be very difficult to help you without providing a lot more information. I suggest first using rostopic echo
to make sure the topics are publishing (e.g., /line_markers
and /line_segments
) and that you've added /line_markers
in rviz. You also need to make sure the scan_topic
parameter is properly set to the topic on which your LaserScan
messages are being published.

When I run rostopic echo /line_markers command, can see data and changes of points on terminal. But when i try to add markers on Rviz, shows "frame[map] does not exist" error
from laser_line_extraction.
It is really hard to estimate what you wanna express.

Hello, maybe I can help.
The lines are represented by its markers on Rviz. The error message you mentioned maybe can be solved editing the launch file, using an existing frame in your data.
In my case, I am using map frame too. Remember to change, in Rviz, the topic of markers (line_markers), and the fixed frame (/map). If this does not solve, maybe your data does not really have the map frame. It starts when you use a map server, like hector or geomapping.
Beside roslaunch laser_line_extraction example.launch, you should also run roslaunch hector or any other launch file that contains a map server to start.
