Used for the following case

  • When identifying the shape of measurement objects (for detecting defects and foreign matters)

Item Name
Description
Model
This item registers the feature images as a model.
Model parameter can be changed as needed to address unstable measurement results or to improve the processing speed. Usually, the factory default value can be used.
[Model (Search)]
Region setting
This item specifies the region to be measured.
Instead of measuring the entire input image, narrowing the measurement region shortens the processing time.
[Region Setting (Search)]
Detection point
This item can be changed if necessary. Specify a position in the model that should be used as the detection coordinates during measurement. Usually, the central position of the set model is registered as the detection coordinates.
[Detection point (Search)]
Reference position
This item can be changed if necessary. Specify the reference position within the camera's field of view.
[Reference Position (Search)]
Measurement
This item specifies judgement conditions for measurement results. Set up OK criterion with which the coordinates (X, Y) of the measurement results and their corresponding evaluation value on the model will be judged.
[Measurement (Search)]
Output parameter
This item can be changed if necessary. Usually, the factory default value can be used.
Use the Output parameter to specify how to treat the coordinate.
