Part Registration
Clicking the <Ex Param> button will display the following dialog box. The value
from 0 up to 10 can be set in the <Body Sub Sample> edit box of the <Extra
Parameter> tab dialog box.
The value set here determines the fineness when creating the outline of the part in
the SM Vision window.
If the image displayed in the SM Vision window has a lot of noise or is unclear, set
its value to the default value of ‘0’.
If the image is clear and therefore the outline of the part can be distinguished
plainly, the part outline can be created with fine detail.
However, if the outline becomes rough due to an over-increase in the value, the
part may not be recognized correctly.

When recognizing a part, the part recognition center can be designated by
dragging the crosshair with the mouse.
At this time, the center of the camera becomes the part recognition center by
default. Match the recognition center (origin point) of the polygon part to be
recognized with the crosshair center. Then the crosshair center becomes the
center of the area in which the polygon part is to be searched.
