Hello. I ask for the help of specialists.
I need to calibrate the camera. Image size 1920 × 1200 pixels. The size of the visible area is 1287 × 810 mm. To minimize distortion, I need to use an A1 size template (594 x 841 mm). Can you please tell me what size the dots should be on a template of this size? Maybe there is a formula to calculate the size of the points depending on the size of the template?
This is a snapshot of an existing template. However, it was noted that the size of the points should be larger.
