Mark Sizes D1 [mm] and D2 [mm]

Set the size of the ﬁducial mark.

•

Data Input Range

Mark Size D1 :

0.50 to 3.00

Mark Size D2 :

0.00 to 3.00

Reference

Refer to "1.2.4 Fiducial Marks" for details.

(A03_04)

Angle [deg]

Set the angle at which a ﬁducial mark should be turned clockwise.

•

Data Input Range

0, 90, 180, 270

Note

(a) A numerical value must be entered in increments of 90°.

When a value other than the speciﬁed increments is entered, the

"Information" window appears, indicating that the entered value

(angle) is changed to "0°", "90°", "180°" or "270°".

(b) When "Thru Hole/Land" is selected in the "Mark Type" (A03_02)

combo box, the color of the angle cell is highlighted and "000.00" is

set in the "Angle [deg]" text box.

(A03_05)

Window Size [mm]

Set the recognition area (complete square) for the PEC recognition

function.

Set preferably small values to avoid false recognition and shorten

recognition time.

Mark Image

Select one of the following options as an image of the mark pattern to

be captured by the camera.

Select either mode according to the difference in contrast between a

mark pattern and its surroundings to get a clear ﬁducial images.

Bright (Normal) :

Bright Fiducial/Dark Background

Dark (Inverted)

Dark Fiducial/Bright Background

Note

Wrong mode selection causes malfunction of the recognition.

(A03_07)

Mark Level

Set the threshold levels of the ﬁducial marks.

In normal cases, set "High".

High :

Both identity and similarity between the shape of a

ﬁducial mark and the real image are detected on a high

level.

Middle :

Eit

her identity or similarity between the shape of a ﬁducial

mark and the real image are detected on a middle level.

Low :

Both identity and similarity between the shape of a

ﬁducial mark and the real image are detected on a low

level.

Note

(a) Identity : Degree of identity between the shapes of the speciﬁed

mark and the real image (including the size)

(b) Similarity : Degree of similarity between the shapes of the speciﬁed

mark and the real image
