Describe the bug There is an issue with the point cloud visualization

Expected behavior Hello, your work is great. I can successfully operate on Docker, but I encountered some problems when using the source code. When I am preprocessing the data, the visualization window crashes and shows a "Segmentation fault". If I do not perform visualization operations, the data processing can proceed normally. When manually selecting points in the second step, a "double free or corruption (out)" error occurred.

The error may stem from the docker environment failing to access X11. Can you try running xhost + before launching the docker environment? Please also check if X11-related docker options are set as following: koide3.github.io/direct_visual_lidar_calibration/docker/

Maybe my my solution can help #123

Thanks for sharing the solution @zhh2005757 . I also think manually providing camera intrinsic parameters may help because it looks the program failed to find the camera_info topic.
