[Model (Classification)]

Register the classification reference as models beforehand.
The model can be registered within Index 0 to 35, and up to 5 models can be registered for one index.
Where variance of the printing quality and shape, more than one models should be registered in the same index.
Important
  • When a model is registered, the central coordinates of the model are registered as the detection coordinates (if multiple figures are combined, the central coordinates of the circumscribed rectangle are registered). For this, ensure the position of the measurement object to be correct when registering a model.
    Illustration of Detection coordinate
  1. In the "Item tab" area, tap [Model].
  2. If necessary, set up the "Model parameter" area.

    Model Status and Measurement
    • The model state may affect the measurement time and accuracy as follows. Please select in-good-state (clean) measurement objects during Model.
      • In the case of big or complicated model, processing time is prolonged.
      • In the case of extremely small model, or absence of features, search is unstable.
  6. To register two or more models, repeat the Steps 3 to 5.
For the following operations, seeSetting up [Classification].

Changing [Model Parameter]

This item can be changed if necessary. Usually, the factory default value can be used.
When any settings have been changed, verify whether measurements can be performed correctly through actual measurement.
Note
  1. In the "Model parameter" area, select the search detection method and specify a value for each item.
    Model - Model Parameter Area
    Table: Model - Model Parameter
    Setting Item
    Set Value
    [Factory Default]
    Description
    Search mode
    [CR]
    This search mode detects areas with a high degree of correlation between the registered model image and the input image.
    PT
    This search mode detects areas with a high degree of shape similarity between the registered model image and the input image.
    It is available only when 3 Mega pixel color camera is connected.

    Set Value
    [Factory Default]
    Description
    Rotation
    • Checked
    • [Unchecked]
    Specify whether to rotate the image during a search.
    Angle range
    Upper
    -180 to [180]
    Specify the upper and lower limit values for [Angle range] (rotation angle) during a search. The normal direction is clockwise.
    Settings must satisfy: lower limit ≦upper limit.
    Lower
    [-180] to 180
    Skipping angle
    1 to 30
    [5]
    Specify the stepping angle (in degrees) by which the model is rotated to create rotated models. A smaller angle increases stability, but slows down the processing.
    Smart mode
    • [Checked]
    • Unchecked
    Specify whether or not to enable Smart mode.
    Checking the [Smart mode] option enables a high-speed rotation search. The stability may be lowered when the model shape aspect ratio is large or when the NOT mask is used.
    Stab. (Stability)
    1 to 15
    [9] (for cameras with more than 640 by 480 pixels)
    [12] (for cameras with 640 by 480 pixels or less)
    Specify the stability of detection. A larger value increases stability. A smaller value speeds up processing.
    If lowering stability leads to slower processing, it is likely that many candidates have been detected. In this case, specify a larger value for [Candidate LV] or [Stab.].
    Prec. (Precision)
    1 to 3
    [2]
    Specify the position precision of the measurement coordinates. A larger value increases precision, and a smaller value speeds up processing.
    1. If necessary, check "Rotation" and specify a value for each rotation item.
      For "Angle range" and "Skipping angle", tap [...] and specify a range of the rotation angle.
      How to input a value: User's Manual, "Inputting a Value"
      The "Skipping angle" value can be adjusted by tapping [<] or [>].
    2. The values for "Stab." and "Prec." can be specified by dragging the slider.
      The value can also be adjusted by tapping the buttons at both ends of the slider.

    Description
    Rotation
    • [Checked]
    When "PT" is selected for "Search mode", search cannot be performed without rotation.
    Angle range
    Upper
    -180 to [180]
    Specify the upper and lower limit values for "Angle range" (rotation angle) during a search. The normal direction is clockwise.
    Settings must satisfy: lower limit ≦ upper limit.
    Lower
    [-180] to 180
    Stab. (Stability)
    1 to 5
    [3]
    Specify the stability of detection. A larger value increases stability, and a smaller value speeds up processing.
    If lowering stability leads to slower processing, it is likely that many candidates have been detected. In this case, specify a larger value for "Candidate LV" or "Stab.".
    1. If necessary, specify a value for each item.
      Tap [...] for "Angle range" and specify the range of the rotation angle.
      How to input a value: User's Manual, "Inputting a Value"
    2. The value for "Stab." can be specified by dragging the slider.
      The value can also be adjusted by tapping the buttons at both ends of the slider.
Points on Adjustment
To improve measurement results, make adjustments as described below.
For adjustments, see also User's Manual, "Points on Adjustment".
When measurement results are unstable
  • If the model image consists of detailed figures, specify a larger value for "Stab.".
  • If images that should be judged OK based on the model image vary in some degree, specify a smaller value for "Candidate LV".
  • If the measurement results are unstable only when "Rotation" is selected, specify a smaller value for "Skipping angle".
  • When "Rotation" is selected, if the model region shape is complex, uncheck the "Smart mode" option.
When the processing speed is slow
  • If the model image is a simple figure or a large figure, specify a smaller value for "Stab.".
  • If images that should be judged OK based on the model image, have less variation, specify a larger value for "Candidate LV".
  • When "Rotation" is selected, if the model image is a simple figure, specify a larger value for "Skipping angle".
  • When "Rotation" is selected, if the model region shape is simple, check the "Smart mode" option.
For other adjustment methods, see User's Manual, "Shortening Measurement Time by Setting Processing Item".
