Position Compensation

The position deflection of measurement objects can be corrected using measured values saved by other processing units. By comparing the measured coordinate with the reference coordinates, which were read from the previous unit, the image is scrolled by the amount of that difference.

Used for 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, thus eliminating the need to replace the measurement object.

Other Processing items combined with Position Compensation

In [Position Compensation], the position is corrected according to the measured values (coordinates) from the previous unit. By combining the following processing items, the result of Position Compensation will be better.

Table: Processing Items Combined with Position Compensation
Processing Unit Type	Processing Item Name
Processing unit that performs search or matching (called "Search Unit" hereafter.)	Search Flexible Search ECM Search Circle Angle
Processing unit that measures the edge position (the following called "Edge position Unit".)	Edge Position Scan Edge Position
Processing unit to detect the center of gravity (Hereafter referred to as "processing unit for gravity center detection".)	Gravity and Area Labeling

Important

When the position compensation method ([Scroll method]) is set to [1 unit scroll] or [2 unit scroll], scrolling will not be correctly performed if units other than the above unit(s) are used immediately before the [Position Compensation] unit within the scene.
[Scroll method (Position Compensation)]
For Processing Items that are used in combination with [Position Compensation], set [Calibration] to "OFF" in [Output parameter].
