  • Page 22: General Characteristics Tab

    Examining the Results In verifications where a symbol passes all quality parameters but fails the acceptance criteria for another reason such as data parsing error or x-dimension range, the grade is shown as an F. For example, if a symbol receives an overall grade of A (4.0) but fails for an X-dimension out of range, grade trending marks the data point as an F.

    Settings Settings This section describes the settings you can make and the options you have in the TruCheck Verification window. Accessing the Settings Menu To access Settings, select the Settings icon in the upper left hand corner of the TruCheck Verification window. Application Settings The content of the Application Settings window depends on the Application Standard selected, since the application standard setting automatically sets many parameters.
  • Page 29 Settings GS1 application standard follows GS1 General Specification guidelines in code verification. GS1 General Specification Tables 1-11 describe several categories of applications. Select from the tables to specify the application category for your codes. Consider the following examples: Note: The DM475 Verifier uses the X-dimension of the decoded symbol to deduce which table applies. If your X- dimension is outside of the range allowed in your application, results will be incorrect.
  • Page 30 Settings Specify either the ISO 15415 grading or the ISO 29158 (AIM-DPM) grading for the MIL-STD-130 UID Application Standard.

    ISO 29158 (AIM-DPM): With ISO 29158 (AIM-DPM), you can select Dot Peen. When using AIM-DPM Grading, verification uses X-dimension range instead of the aperture setting in accordance with the AIM-DPM methodology. For more information, visit support.cognex.com, and navigate to Resources > Introduction to Barcode Verification. Data Format Check You can apply a specific Data Format Check criteria to the data content of the code or leave the option as None.
  • Page 33 Settings GS1: The GS1 option checks the format of the data against GS1 formatting rules. GS1 codes generally begin with a Function 1 <F1> character. HIBCC: The HIBCC option checks the format of the data against HIBCC formatting rules. HIBCC codes generally begin with a + character.
  • Page 34 Settings Aperture Setting Aperture setting refers to a synthetic aperture as opposed to an optical aperture. Aperture is a circular region imposed on the pixels which comprise the individual modules making up the code. This process is mandated by the ISO 15415 and 15416 standards.

  • Page 42: Grading Standards And Their Parameters

    Grading Standards and their Parameters Grading Standards and their Parameters Depending on the application two global quality grading standards are available for 2D symbols: ISO 15415 ISO 29158 (AIM-DPM) ISO/IEC 15415 Grading Parameters The ISO/IEC 15415 standard specifies those measuring, evaluating and grading methods and parameters, which determine the quality of 2D symbols, and identifies possible causes of symbol errors.
  • Page 43 Grading Standards and their Parameters reported as Contrast Uniformity (CU) in General Characteristics to facilitate conformance testing to the requirements of ISO/IEC 15426-2. The RM parameter works in a similar way, except that for modules which are corrected as errors by the error correction, the MOD% is taken as 0 and counts as F in the final evaluation of the Modulation parameter grade according to the notional Unused Error Correction grade.
  • Page 44 Grading Standards and their Parameters Second requirement: - Grade assigned according to the table is not fail. - The grade is calculated by the percentage of correct modules BLS (Bottom ‘L’ Side) is a grade based on imperfections in the bottom ‘L’ side of the finder pattern (see Left ‘L’...
  • Page 45 Grading Standards and their Parameters Transition Ratio % Grade 8 < x ≤ 10 C (2.0) 10 < x ≤ 12 D (1.0) 12 < x F (0) ULQTTR (Transition ratio for Upper Left Quadrant Top Clock Track): Only for 4 quadrant symbols, this is the grade based on the clock track segment at the top of the upper left quadrant.

  • Page 46: Iso 18004 Qr Code Grading Parameters

    Grading Standards and their Parameters RCT (Right Clock Track) is a grade based on imperfection in the right clock track. Some imperfections in the clock track can be tolerated. As a rule maintaining for a passing grade is that three out of every five modules on a consecutively rolling window of five modules must be correct.

  • Page 47: Iso 29158 (Aim-Dpm) 2006 Grading Parameters

    Grading Standards and their Parameters HCT (Horizontal Clock Track): The horizontal timing pattern consisting of a one module row of alternating dark and light modules. VCT (Vertical Clock Track): The vertical timing pattern consisting of a one module row of alternating dark and light modules.

  • Page 48: Traditional (Non-Graded) Parameters

    Grading Standards and their Parameters Grade ≥ 30% ≥ 25% ≥ 20% ≥ 15% < 15% CMOD (Cell Modulation): Similar to MOD in ISO 15415, CMOD measures the deviation in the reflectivity of dark and light elements. A range for each light and dark group is created from the global threshold to the mean reflectance of the elements.
  • Page 49 Grading Standards and their Parameters When a code is not read, the scan is analyzed for apparent quiet zones and the bars and spaces in between are used for the ANSI analysis. 1. EDGE: Edge Determination Checks if the edge between bar and space can be detected and no false bars or spaces appear due to “splitting” of bars or ink splattered in spaces.
  • Page 50 Grading Standards and their Parameters 5. MOD: Modulation Modulation checks the edge contrast as a fraction of the overall or best case contrast measured in symbol contrast. Modulation is a measure of minimum edge contrast since most barcode readers employ adaptive thresholding circuits to detect transitions between bars and spaces.
  • Page 51 Grading Standards and their Parameters 8. DEC: Decodability Determines how accurate the bar and space widths are and how easily the widths can be determined. A perfectly accurate barcode has 100 percent decodability, but decodability as low as 25 percent is often acceptable. Decodability is the percentage of the overall tolerance range for a bar or space width that is not used up by inaccuracies.
