FH/FZ5 Processing Item Function Reference Manual
Set the grid points to be edited or deleted from
the list.
Click [Edit] or [Delete].
If you clicked [Edit], execute StepReference: 7. (p.643)
11 Click [Generate calibration parameters].
The calibration parameters will be generated.
Height Adjustment (Precise Calibration)
Even if the plane height is different for calibration and for measurement, adjust so that the correct coordinates
can be corrected for.
1 In the Item Tab area, click [Height adjustment].
2 Select "ON" in the Height adjustment
area.
• After generating calibration parameters, if you edit or delete coordinates, the calibration parameters are updated.
• The deleted coordinates are deleted from the list.
• If the precision of input grid points is poor, parameter generation may fail. Set again so that the grid points are
shown clearly.
• The precision error is a yardstick for calibration
,
not a guarantee of actual precision.
• The height adjustment is only valid when the camera is facing the
measurement object level. If the camera is tilted, it
may be impossible to correct the image accurately.
• The results of height adjustment are not applied to image correction.
