Time lag while displaying output

[rupikaraj]

Hi there, I was able to successfully run this code. The GUIs for point selection and the final projected output windows shows a time lag of about 5 to 10 seconds. I'm not sure if my system meets the requirements, could you please share the system specifications that you used to run this code?"

I am using the following:
** Ouster OS1 LiDAR
** Logitech webcam
** ROS Melodic
** Jetson xavier nx developer kit
** Ubuntu 18.04

If this issue is not because of system specs, then could you suggest a solution?
Thanks in advance.
