Processing Units That Can Be Combined with Position Compensation
Position compensation corrects positions according to measured values (coordinates) from the immediately
preceding processing unit. Combining the following processing units with position compensation is effective.
Region Setting (Position Compensation)
When position compensation is set, the position is shifted by exactly the amount of the compensation, then
measurement is performed. Restricting the region in which the image is moved can shorten the processing time.
1 In the Item Tab area, click [Region setting].
2 Use the Drawing tools to specify the measurement region.
3 Click [OK] in the Figure setting area.
• [OK]: Changes the settings and returns to the previous menu.
• [Cancel]: Changes are discarded. R
eturns to the previous menu.
• [Apply]: Updates the settings without leaving edit window.
Scroll Method (Position Compensation)
Set the compensation method for position compensation.
1 In the Item Tab area, click [Scroll method].
2 Set the parameters.

Processing unit that performs search or matching
(called "Search processing unit" hereafter. )
Reference: Search (p.95)
Reference: Flexible Search (p.110)
Reference: ECM Search (p.132)
Reference: Circle Angle (p.488)
Processing unit that detect
s edge positions
(called "Edge position processing unit" hereafter. )
Reference: Edge Position (p.224)
Reference: Scan Edge Position (p.243)
Processing unit to detect the center of gravity
(called "processing unit for gravity center detection". )
Reference: Gravity and Area (p.317)
Reference: Labeling (p.331)
• When the position compensation method ([Method]) is set to [1
unit scroll] or [2 unit scroll], position compensation will not
be performed correctly if units other than the above unit(s) are present immediately before the [Position Compensation]
unit within the scene.
• For processing units that are used in combination with positio
n compensation, set [Calibration] to "OFF" in [Output
parameter].
• The position compensation method causes some processing items to
be NG when
areas outside the image are included
within the region. (Edge position/number of edge pins/fine matching/defects and contamination/ high-precision defects
and contamination detection/area gravity center/labeling/sophisticated labeling+/color average and deviation/scan edge
position/scan edge width/circular shape angle acquisition)
