Hi, all! I am using camera calibration node for monocular camera. Is there any criterion that says how well the camera was calibrated? And the second question is: should I pass rectified image to some algorithm after calibration or it will be redundant?

According to the official ROS documentation available here you can check your calibration using cameracheck.py the following way:

rosrun camera_calibration cameracheck.py --size 8x6 monocular:=/forearm image:=image_rect

Remember that you need to click COMMIT after your calibration is done for the calibration parameters to be uploaded to the camera driver.

Hi! You can pass the camera matrix to image rect and check wether the undistorted image looks good or not.

As I understood from your post the quality is measured by sight.
