[Model (Model Dictionary)]

This item registers the feature image of the measured objects as a model and displays a model list.
Models can be registered in one of 36 index types (0 to 35), and up to five models can be registered per 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 reason, place the measurement object in the correct position when registering a model.
    Illustration of detection point
  1. In the "Item tab" area, tap [Model].
    When setting a new model, you do not have to tap [Model].
  2. If necessary, set up the "Model parameter" area.
    Changing Model Parameters
  3. In the "Setting model" area, select a model and tap [New].
    Model - Setting Model Area
    The "Detail" area for model registration is displayed.
  4. Specify a region to be registered as a model by using the Drawing tools.

    Note
    • If the model is an ellipse, its circumscribed rectangle is displayed as the search result of the model.
  5. Tap [OK].
    The model is registered and its central X and Y coordinate values are displayed in the "Setting model" area.

    The image specified for the model is displayed in the "Image display" area.

  6. To register two or more models, repeat the Steps 3 to 5.
  7. In the "String setting" area, tap [...] for each item as necessary.
    Model - String setting Area
    A software keyboard is displayed.
    The number of characters for each string is fixed to 12 characters.

Changing Model Parameters

This item can be changed if necessary. Usually, the factory default value can be used.
When any settings are changed, verify whether measurements can be performed correctly through actual measurements.
Note
  1. In the "Model parameter" area, specify a value for each item.
    Model - Model parameter area
    Table: Model - Model Parameter
    Setting Item
    Set Value
    [Factory default]
    Description
    Rotation
    • Checked
    • [Unchecked]
    Specify whether to rotate the image during a search.
    Angle range
    Upper
    -45 to 45
    [0]
    Specify the upper and lower limits for [Angle range] (rotation angle) during a search. The normal direction is clockwise.
    Settings must satisfy: The lower limit is equal to or smaller than the upper limit.
    Lower
    -45 to 45
    [0]
    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
    [13]
    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 raises precision, and a smaller value speeds up processing.
    1. If necessary, check [Rotation] and specify a value for each rotation item.
      For [Angle range], tap [...] and specify a range for the rotation angle.
      How to input a value: User's Manual, "Inputting a Value"
    2. The values for "Stab." and [Prec.] can be adjusted 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".
  • 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 and 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".
