Taking Images
If you select [Bilinear], the precision of position compensation will increase.
[Image] − [Image adjustment] − [Shape Sear. pos. comp.] − [Modify]
1 Press [Details] − [Scroll parameter] − [Interpolation]
2 Set the interpolation to [Bilinear] or [None].
• Measurement Data That Can Be Used for External Outputs and Calculations
The following values can be used as measurement data and output to external devices via Ethernet or used in
calculations.
Search Position Compensation
With this position compensation item, an image pattern is registered in advance. When the registered image
pattern is detected, the image is adjusted so that the image pattern is in the same position as when it was
registered.
This position compensation item performs the same type of processing as the Shape Search Position
Compensation item, but it performs processing to detect differences in colors and patterns in addition to
processing for image pattern shapes.
[Image] − [Image adjustment]
Parameter Setting Description
Interpolation Bilinear (default) Points are connected with lines to find approximations. This create smoother
images.
None Position compensation is performed at the pixel level.
Expression text string Data name Description Data range
JG Judgement This is the judgement result. −2: No judgement (not measured),
0: Judgement is OK,
−1: Judgement is NG

sation for the X coordinate.

where the model was registered.
−99,999.9999 to 99,999.9999
SY Reference Y This is the Y coordinate of the position
where the model was registered.
−99,999.9999 to 99,999.9999
ST Reference angle This is the angle when the model was
registered.
−180 to 180
CR Correlation This is the correlation. 0 to 100
To perform position compensation for a rotated image pattern, use the Shape Search Position Compensation item.
