9. Please describe the issue in detail.

   • After running all of the code in the auto race manual, the intrinsic camera calibration for the detection of lines on a track refuses to open. This works on a seperate computer, but not this one. There is no issue with the installation, all lines have been followed exactly as posted in the noetic version of the tutorial intrinsic_camera_calibration.txt

Hello. @kylehannibal.

Please enter the $ ls /dev/video0 command to check whether the camera is recognized by Turtlebot3.

Intrinsic camera calibration is the step of calibrating the inside of the camera. So the extrinsic camera calibration will detect the lines on the track.

thank you.
