Hello, I am trying to calibrate usb camera using image_calibrate on ROS Melodic. My machine is a 4gb Jetson Nano running ubuntu 18.04 LTS. I am following a tutorial for the Yahboom Transbot kit (see ROS HD camera 8.1 calibration). The package seems to be running correctly: the calibration grid is appearing and it was able to recognize enough different poses to fill all 3 bars until they changed to green. Two problems: 1) The calibration button is lit green, but nothing happens when I click it, even after several minutes. 2) I am not seeing camera type or scale sliders as they appear in the tutorial image.
