8 Configuration steps8.1 Image quality

To ensure reliable code recognition adjust and set the reader so that the following criteria are met: ►

The code has to be set to be sharp and should be of the highest possible contrast (ideal = black/ –white)�The code has to be displayed within the search zone� –The size of the code in the image should be no larger than approx� 2/3 of the image� –The minimum module size of the code has to be taken into account for selecting the operating –distance� (Operating instructions "dualis multicode reader O2I1xx" or www�ifm�com → Data sheet direct: → e.g. O2I102 → Additional data.)Any code position is possible� –

If there is any interfering reflectance in the image, install the device transversely to the code plane, if necessary� Depending on the code size the resulting trapezoidal distortion can be tolerated within certain limits�

Optimise the image definition via the setting screw on the back of the device� ►

To maximise the reading/verification reliability and rate adjust the blue search zone� ►In the running process the code has to be seen within the search zone� –Only image data from that search zone will be used for reading/verification� –The reading/verification rate largely depends on the size of the search zone� Therefore do not leave –the search zone unnecessarily in its maximum size in time-critical applications�

Switch the lighting segments on and off according to the application and the light conditions� ►The code should be equally illuminated� The 4 segments of the internal illumination can be activated independently with a mouse click on the segments (factory setting = internal illumination, 4 segments "on").

8.2 Defining the code

When a new configuration is created, the program automatically performs a code recognition process after the change from "Image quality" →"Define code". This may take several seconds.

8.2.1 Standard recognition and extended recognition Preferred for code applications with good contrast, surface and light conditions� No filter functions are necessary� The application does not have any time-critical requirements�

Select or leave [Standard recognition]� ►

Parameters Standard recognition (default setting)

Extended recognition

Module colour Dark symbols on light background Dark symbols on light background and light symbols on dark background

Min� contrast [%]: 30 % 10 %

Module size ECC200 QR

6��20 pixels ≥ 4 pixels (for high contrast images ≥ 2 pixels)

PDF417 3��15 pixels ≥ 3 pixels (for high contrast images ≥ 2 pixels)

Column and row spacing No or small distance between adjoining modules (≤ 10 % of the module size)

Greater distances possible (≤ 50 % of the module size)

Max� inclination ECC200 10° 30°

Enter number of codes in the search zone� ►(Codes of the same type!)

Select the code type in the pulldown menu� ►If the code type to be recognised is not known, select [Automatic recognition]�


28

Depending on the volume of the image information to be processed automatic code recognition may take several seconds�

The result field shows the code type and the number of codes recognised� >

Select [Read code]� ►

The result field shows: >Number of codes found (figure) Number of codes searched (figure) Code string (contents) Total decoding time (ms) Total time (ms)

The recognised codes are displayed in a green, numbered code field� >When the mouse pointer is moved above the green code field, a tool tip will open giving specific code information (here e�g� code type, status of code recognition, polarity, code size, etc�)�

Continue to the next step "Process interface" with [Next]. ►

If code recognition and the reading process were not successful, repeat the process with the setting "Extended recognition" → �

If this setting is not successful, either, repeat the process with the filter functions of "Preprocessing" (→ 8�2�2)�

29


UK

8.2.2 Preprocessing (filter functions)In difficult applications that cannot be read with the standard or extended recognition� This may for example be the case for codes on curved, reflective surfaces or for codes with heavy soiling�

Select the register [Preprocessing]� ►

Select the filter function(s)� ►An internal trigger pulse is activated; the image data is transferred to the operating program� >The effect of a filter function can be seen directly in the image field�

Filter functions Description

Smoothing Smoothing filterRemoves/suppresses noise and noise pixels (filter intensity divided into 1x, 2x, 3x)

Enlarge dark pixels Correction of modules that are too smallEnlarges/combines dark pixel groups Decreases/removes light pixel gaps (filter intensity divided in 1x, 2x)

Enlarge light pixels Correction of modules that are too largeEnlarges/combines light pixel groups Decreases/removes dark pixel groups (filter intensity divided in 1x, 2x)

A combination of up to 3 filters ensures optimisation for special cases� The individual filter functions are applied to the field of view one after the other�

Each filter function requires some calculation time and decreases the obtainable reading/verification rate in the process�

Return to the initial menu by clicking on the register [Code type]� ►

Define the number of codes in the search zone [Codes per image]� ►(Codes of the same type!)

Select the code type in the pulldown menu� ►If the code type to be recognised is not known, select [Automatic recognition]�The image in the reading range changes form "Live" to "Freeze". >The recognised code type is displayed in the result field� >

Select [Read code]� ►The result field shows: >Number of codes found (figure) Number of codes searched (figure) Code string (contents) Total decoding time (ms) Total time (ms)

Continue to the next step "Process interface" with [Next] (→ 8.3). ►

If code recognition and the reading process were not successful, repeat the process with other filter functions�

8.3.1 Code qualityThere is an assessment of the code quality for the code types ECC200, QR and PDF417� For other code types the register field [Quality] is suppressed�

Select [Quality] (here e�g� ECC200)� ►The selection menu with quality features is displayed� >

The ISO/IEC standard 15415 defines various features to assess the quality of an ECC200, QR or PDF417 code. These features are analysed independently and rated from 0...4 (4 = very good, 0 = not passed)�

Feature ECC200 QR PDF417 Description

Overall quality ● ● ● Overall quality of the code� Corresponds to the individual feature with the worst rating�

Contrast ● ● – Contrast of the modules to the background�

Modulation ● ● ● Homogeneity of the light and dark modules�

Finder pattern damage ● ● – Error rate in the 3 basic elements of the code (finder pattern, alternating pattern and quiet zone)�

Decoding ● ● ● Rating 4 if the code can be decoded, otherwise 0�

Axial non-uniformity ● ● – Ratio of the module size in horizontal and vertical direction�

Grid distortion ● ● – A measure for how far the module corresponds to the symbol grid�

Unused error correction ● ● ● A measure for the degree of distortion of the code and what part of the existing error correction mechanisms was necessary to nevertheless decode the code successfully�

Defects – – ● Assessment of the bar/gap representation of the code�

Start /stop pattern – – ● Assessment of the start/stop pattern�

Codeword yield – – ● Assessment of the relative number of correctly decoded words�

● = feature relevant / – = feature not relevant
