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.
Note
To perform position compensation for a rotated image pattern, use the Shape Search Position Compensation item.

Setting
Points are connected with lines to find approximations. This create smoother
images.
Position compensation is performed at the pixel level.
Description
This is the judgement result.
This is the amount of position compen-
sation for the X coordinate.
This is the amount of position compen-
sation for the Y coordinate.
This is the amount of angular compen-
sation, θ.
This is the X coordinate of the position
where the model was found.
This is the Y coordinate of the position
where the model was found.
This is the angle at which the model
was found.
This is the X coordinate of the position
where the model was registered.
This is the Y coordinate of the position
where the model was registered.
This is the angle when the model was
registered.
This is the correlation.
