hello, i am having troubles making this work. I can launch the calibrator and see a greyscale image, but i can not see the highlights on the chessboard, do you know what the problem is?
thank you in advance

@OsmanDumbuya

I've followed the instructions outlined in the ROS wiki tutorial ( http://wiki.ros.org/camera_calibration/Tutorials/MonocularCalibration ), but I'm unable to successfully open the calibration screen. Everything runs fine with no errors, but the calibration screen just loads up grey when I $ rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 image:=/camera/image_raw camera:=/camera --no-service-check. I already have all the necessary drives installed for the astra pro camera. Please help

Anyone who is facing problem, please note the size is number of internal corners of the square.
