10-2 General Inspection Methodology

The Gain Offset Enhancement algorithm has two adjustable parameters that can be set in the

Image Gain and Offset Adjustment dialog.

10.2 Mark Inspection

Mark inspection is designed to verify the markings on the part. The default algorithm for mark

inspection is pattern matching. Other available algorithms are barcode reading, edge locator and

surface reference. There can be more than one mark inspection box per part.

After the Mark inspection box is created, you can display the Mark pop-up menu by pressing the

right mouse button while pointing at the inspection box.

Edit Mark Params..

Launches the Mark Parameter dialog. See 10.2.1 Edit Mark

Parameters.

Train Alternate

Train alternate template for Pattern Match algorithm.

Display Template

Display the templates trained.

Edit Alternate

Edit each alternate template. See 10.2.2 Edit Alternate

Set Search Area

Set the area on the image inside of which the software will

search for a match. This operation will change the Search

Margin parameter.

Train Dependent Tmp

Add a dependent template to the current alternate template.

Set Ref. Position

Allows user to set up a template position as being a (0, 0)

reference position.

Skip/Unskip

Allows user to either skip or unskip this mark inspection.

Move

Move the mark inspection box.

Delete

Delete this mark inspection box.

Test

Run the test on this inspection box.

Bar Code Params..

Available only when Bar Code is selected as the decision

algorithm menu item. See 10.2.3 Bar Code Parameters

Edge Locator Params..

Available only when Edge Locator is selected as the

decision algorithm menu item. See 10.2.4 Edge Locator

Parameters.

10.2.1 Edit Mark Parameters

Select Edit Mark Params from the Mark pop-up menu to open the Edit Mark Parameters dialog.

The Camera View group selects the view of the inspection. For 2D X-ray inspection, the Slice

View box must be unchecked and the Slice No. field doesn’t matter. For 3D inspection, the Slice

View box must be checked for slice view images and Slice No. must be specified.

The Lighting group selects the lighting. For X-ray views please select Side Light only.

The X-Ray Power Level field specifies the power level used for current inspection.

The PreProcess pull-down lists the available preprocessing algorithms and the Decision pull-

down lists the decision algorithms.

The Pass Score field, Polarity and Center Mark checkboxes and Search Margin field

parameters apply only to the Pattern Match algorithm. The Pass Score sets the sensitivity of the

acceptance. 100% means a perfect match. Acceptable pass scores for part inspection are between

40 to 80%. If Polarity is unchecked the software will accept images that are rotated 180 degrees

from the original image template. If Center Mark is checked the mark inspection box is always

at the center of the part.
