Position Compensation

The positional deviation of measurement objects can be corrected using measured values saved by other processing units. Compare the measured coordinates with the reference coordinates of the applicable processing unit, and move the image by the amount of the difference.

Used in the Following Case

Even with different positions for the same measurement object, correct measurement can still be performed by correcting the position of the input image.There is no need to reposition the measurement object itself.

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.

Processing unit type	Processing item name
Processing unit that performs search or matching (called "Search processing unit" hereafter.)	Search Flexible Search ECM Search Circle Angle
Processing unit that detects edge positions (called "Edge position processing unit" hereafter.)	Edge Position Scan Edge Position
Processing unit to detect the center of gravity (called "processing unit for gravity center detection".)	Gravity and Area Labeling

Important

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 position 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.
