How to understand the real deviations in image map calibration?
Sorry and happy new year! I have another new question:
Locus's image map calibration is excellent, but I am confused by a question:
How does Locus calculate the real deviations for each predefined point?
According to my understanding, these predefined points are all specified by me.
Why can Locus calculate their real deviations???
I even think why the real deviation of my predefined point can't be 0?
Of course I know this is impossible, but what is the basis of Locus?
