Calibration - Omron ZFX-C User Manual

Calibration

This function converts measurement values from pixels to actual dimensions for output. By setting the
relationship between camera coordinates and actual coordinates, measurement results expressed in pixels
can be converted to actual dimensions and output.
Note
To enable the calibration function, set [Calibration] in the Detail setup screen for each measurement item to [ON].
When [Calibration] is still [OFF] (default value), measurement values are output using camera coordinates and not
the actual dimensions.
Pixel units can be converted to actual dimensions and output.
30 mm
Both the origin and the coordinate system can be corrected.
Actual coordinates origin
Three calibration setup options are available: "Sampling input", "Specifying point" and "Parameter Input".
