Setting Position Displacement Compensation Regions
Register an image pattern (called a model) in advance. The part of an input
image that is most similar to the model is found, the position is calculated in
pixel units, and the degree of similarity is expressed with a correlation value.
Perform processing directly on the density image taken by the Camera.

STEP 1: Registering the Model
Register a characteristic portion as the model for position displacement com-
pensation.
When a model is registered, the center position of the model is registered as
the search coordinates. This position becomes the reference position, so
make sure the measurement object is in the correct position before registering
the model.
CHECK
The size of the model that can be registered depends on the search verifica-
tion setting under Detailed conditions.
No search verification (default): 15
9 to 70
66 pixels
With search verification: No limit
To register large models, change the detailed conditions before registering the
model. Refer to page 2-8-(12).
