Hi,

I am not sure what caused this problem. No modification was made to the Pangolin and it is just used for visualization.

are you using the latest version of Ubuntu and Pangolin? I am not sure if there are compatibility issues. Maybe you can try to install an older version of Pangolin and try again.

or could you try to run the original orb-slam and see if the same problem exists?

let me know if you found out something.

Best,

Hi，
I used the latest Pangolin and tested orbslam without this problem, but in openVslam, it may be related to the version. Through testing I found the problem can be solved by double-click the Follow Camera in Pangolin。

Hello,

thanks again for your testing. Recently, I configured a new gaming laptop with ubuntu 22.04 installed. After I successfully tested ORB-SLAM2 and Stella-SLAM (OpenVSLAM), I found out my system encountered same problem as yours.

The basic visualization code is the same as OpenVSLAM, however I do not see the reason why the map viewer does not show anything in the beginning, which can solved by double click "Follow Camera", but this is not optimal.

Not sure if you have any new findings, please let me know.

Best,
