Calibration is performed on two axes: XY.
Normally, calibration is performed using two axes, but in order to simplify the calibration even a little, our high-definition camera uses a method that allows you to click any three points on a circle.
Calibration will improve if you use as much of the screen as possible.
(Although it is possible to calibrate small parts, the error will become larger (accumulation of errors))
Therefore, you need to choose a circle that is as large as possible.
Not all circles need to be reflected.
It is OK if you can get any three points on the circle as large as possible.
Calibration itself can be done in any of the following ways. However, the error increases when (A) > (B) > (C).
| （A) | （B) | （C) |

It is not necessary that the entire circle is visible.
For example, you can calibrate by selecting three points as shown below.
