STEP 3: Setting Search Regions
Set the region to search for the model. The whole region of the input image
can be searched. Accuracy improved, however, by limiting the search region.
1.
Select Search region.
An arrow cursor will appear.
The model will be displayed with solid lines.
2.
Draw a box-shaped search region.
CHECK
The only figure that can be drawn is a box.
The search region will be set and the screen in (1.) will return.
STEP 4: Setting Judgement Conditions
Set the judgement conditions for the correlation between the measurement
object and the models, the position (X, Y) where the object was detected, and
the angle.

Correlation range (0 to 100)
Range of movement of the measurement object
in the X direction (-9,999.999 to 9,999.999)
Range of movement of the measurement object
in the Y direction (-9,999.999 to 9,999.999)

]
Position X : 180.000
[ 0.000 : 511.000]
Position Y : 250.000
[ 0.000 : 483.000]
Angle : 15.000
[ -180.000 : 180.000]
Range of angles for the measurement object
(-360.000 to 360.000)
(However, the measurement value will be
output in the range -180.000 to 180.000.)
