Vision System FH/FHV/FZ5 Series User’s Manual (Z365)
This section uses two Cameras and a stage as the external device to describe an example for setting
the calibration flow and executing calibration.
Example: Calibration Flow Example for 2 Cameras
10-9-2 Execution of Calibration
Camera Image Input processing item · · · Select Camera 0.
↓
Machine setting processing item · · · Register [stage data] or [robot data] depending on the external
device to be used, and then set the information for the external
device.
The machine setting processing item can be placed anywhere in
the measurement flow other than at the beginning of the mea-
surement flow.
↓
Position measurement processing item · · · Measure the position of the alignment marks to use as the sam-
pling target, or the position of a special feature (such as corners)
of the workpiece from the image in Camera 0.
To output the position on the image, set [Calibration] on the [Out-
put parameter] tab page to OFF.
↓
Camera Switching processing item · · · Select Camera 1.
↓
Position measurement processing item · · · Measure the position of the alignment marks to use as the sam-
pling target, or the position of a special feature (such as corners)
of the workpiece from the image in Camera 1.
To output the position on the image, set [Calibration] on the [Out-
put parameter] tab page to OFF.
↓
Calibration processing items · · · Register [Vision Master Calibration] or [PLC Master Calibration].
Set the machine setting processing item to reference, and then
set the sampling.
↓
Data output processing items · · · Depending on the communications method, register either [Data
output] or [Fieldbus data output].
The Vision Master Calibration processing item may send three
parameters to the PLC: [Axis movement required for sampling],
[Origin return], and [Completion Timing of Calibration].
Each parameter is output after a reference of the calculation for
the Vision Master Calibration processing item is made.
With the PLC Master Calibration processing item, it is not neces-
sary to send data to the PLC, so Data Output processing items
are not necessary.
