Calibration (Camera Image Input Fh) - Omron FH-3 Series Reference Manual

Calibration (Camera Image Input FH)

By setting the calibration, the measurement result can be converted and output as actual dimensions. The
calibration method is selected here.
There are three calibration methods, point, sampling, and parameter.
• Reference: Specifying Points and Setting (Point Specification) (p.66)
• Reference: Setting Calibration through Sampling Measurement (Sampling) (p.67)
• Reference: Inputting and Setting Values (Value Setting) (p.69)
• Reference: View Calibration Parameters (p.70)
Note
• In order to output measurement values in actual dimensions, select [Calibration] to "ON" in [Output parameter] for each
processing unit. If [Calibration] is "OFF" (factory default), measurement results are output as camera image coordinate
values.
Specifying Points and Setting (Point Specification)
This is a method for performing calibration by selecting arbitrary points (in pixels).
Calibration parameters are calculated automatically when actual coordinates of selected locations are entered.
Up to 3 points can be selected.
• When magnification is the same in
the X and Y directions
Select only 2 points.
X : Y = 1 : 1
Note
• When 2 points are selected, the coordinate system is set to the left-hand system (forward in the clockwise direction).
Select 3 points to perform calibration including the coordinate system.
