•Enables automation

•Build a complete manifest

of what goes into a product

•Track from cradle to grave

▪Requirements

•Marking

•Mark quality verification

Code Verification –Check the handwriting

▪Marking processes drift from nominal

settings ultimately leading to unreadable

marks

▪Verification allows adjusting of marking

process before unreadable marks are

made

▪Verification is metrology tool to ensure

consistent mark quality

▪Verifier can tell not only that mark is

readable but also how close it is to edge

of readability that it is

Measurement value

Frequency

▪Offline or Inline symbol verification

▪Verify or validate the symbol immediately after printing

▪Deviate from the standards if process or circumstances require

▪Provide results that correlate directly with ISO standards

▪Verification ensures that EVERY product ships with a good quality symbol despite

the fact that every marking system will degrade over time

Without verification, some “bad”

parts escape into the process With verification, we prevent bad

marks from ever being made.

ISO15416 - 1D Label Verification

▪ISO 15416

•1D on Labels

•Requires even

illumination

•Requires good

lens with high

MTF

ISO15415 - 2D Label Verification

▪ISO 15415

•2D on Labels

•Requires even

illumination

•Requires good

lens with high

MTF

▪Modulation

ISO 29158 - 2D DPM Verification

▪ISO 29158

•Direct Part Marks

•More forgiving spec

•Requires application

specific lighting

© Omron Microscan Systems Inc.18

▪Direct inkjet printing is economical

▪But the results are not always pretty

▪No reads at big retail customers result in fines for each

unreadable code

▪Inline verification after printing ensures NO bad symbols ship

Verification Example: Inkjet on cartons

Code Verifiers

▪Offline

•Handheld label and DPM verifier –LVS-9580, LVS 9585

•Desktop Verifier –LVS-9510

▪Inline

•Fixed mount inline verifier –MicroHAWK MV, HAWK MV-4000

Code Verification at the printing source

© Omron Microscan Systems Inc.21

▪Show and Go Tool - Validate printed text by training on a good sample

▪Detects common printing problems and provides pass/fail output

▪Symbols are compared against trained golden symbol

▪Symbols are rejected if the total residue exceeds the set tolerance

▪Optional tests for Largest single defect, character breaks, contrast, and blurriness

Presence/Absence of Critical Parts and Features

▪Count Pixels

•Within range of

grayscale intensity

•Edge pixels

(brightness

invariant)

▪Tolerance

•Compare count to

min and max values

▪Output

•Pixel count

Presence/Absence using Color

▪Color ID

•Determine color

from library of

colors

▪Color Check

•Compare color to

one specific color

▪Tolerance

•Compare pixel

count to min values

▪Output

•Color

•Count of pixels

•Pass/Fail

© Omron Microscan Systems Inc.29

Count

▪Locate features

•Shape based

Location and Guidance

▪Train a pattern

▪Return X, Y, Theta

▪Add encoder based

offset for “pickup

down the belt”

▪Intellifind Tool

•Edge Based Pattern Matching

•Allows 360 degree rotation

•Allows scale changes

•Lighting invariant

•Finds patterns amongst clutter

© Omron Microscan Systems Inc.33

Assembly

▪Train pattern of points on

each part

▪Compute offset of part 1

to blueprint

▪Compute offset of part 2

to blueprint

▪Compute offset part 1 to

part 2

▪Output X, Y, Theta to

assemble part 1 onto

part two

▪Uses “rigid body fit”

algorithm

Defect Detection

▪Often difficult –Defects similar in size and shape to allowed features

▪Highly dependent on lighting to create contrast

© Omron Microscan Systems Inc.35

Defect Detection –Lighting Dependency

© Omron Microscan Systems Inc.36

Defect Detection –Using OCV

▪OCV is not just for

characters

▪OCV can be used for

individual shapes or

symbols

▪OCV computes

difference between

trained and

inspected shape

▪OCV combined with

color checks is very

powerful

Wrap Up

▪Modern Machine Vision Systems contain tools for

•Automatic Code Identification

•Code Verification

•Machine Vision

▪Traceability is a Strategy that involves

•Picking the correct code types

•Picking the correct code marking methods

•Code Reading

•Code Verification

▪Traditional Machine Vision is used for

•Presence/Absence

•Color ID/Color Match

•Count

•Measurement/Gauging

•Assembly and Assembly Verification
