ITEM Overview (Pattern Search)
An image pattern is registered in beforehand as a model, and theparts that
most resembles an already registered model is searched. The correlation, the
position of most resembled parts, and their angle can be outputted.
Search Process and Search Mode
1.
Roughly Search
The resembled parts in the whole image
are searched roughly.
2.
Detailed Search (Standard Search)
After roughly search, this search would be
done around the roughly searched posi-
tion. Detail correlation and position are
measured.
3.
High-precision Search
After detailed search, this search would be
done around the detail searched position.
More detail correlation and subpixel posi-
tion are measured.
Another setting
Setup
Measurement
Parts resembling the model are searched for.

for searching model)

Search mode
See above
Hi-speed
The search is performed at high speed.
Normal (default)
The search is performed at normal speed
and normal accuracy.
Precision
The position is calculated at high precision
in sub-pixel (smaller than pixel).
Rotation Range
Rotation range: 0 to 180 (default value: 0)
Skipping angle: 1, 2, 3, 5, 10, 15, 20, 30 (default value: 10)
It is possible to find the most resembled image to rotate. In case
that Rotation Range is set to more than 0, many angled models
are registered automatically. And search process is done for
each model.
E.g. Rotation Range: 15, Skipping Angle: 5
