Calibration
Calibration is used to convert Camera coordinates into actual coordinates.
You can set calibration to output the detected position in the actual coordinates.
You can convert pixels to actual dimensions and then output them.
You can also compensate for offsets in the origin and coordinate system.
• Calibration Conversion Methods
There are the following three conversion methods for calibration.
Point specification: You can enter the actual pixel coordinates of any position.
Reference: You can measure a registered model and then enter the actual coordinates of the model.
Parameter: You can enter the calibration values directly.
