The error value of calibration image is large
Hello sir,your software helped me a lot. I have one question to ask you when I use it.The two error values of the calibration board image I calibrated are very large. Is there any way to reduce the root mean square error and average limit error? In the example, the calibration result is less than 0.5, while my result is greater than 2. Looking forward to your help, thank you.
It could be that your calibration plate is out of focus. The calibration depends on a crisp location for the corners of the calibration plate. If you zoom in you can see that these corners may be hard to define. Another possibility is that you don't have enough calibration images or enough orientations of the calibration plate taking up the field of view to get a small calibration error. These are just a couple thoughts, but maybe a good starting point to getting a better calibration.
