Search

Register the feature sections of the measurement object as an image pattern
(model), then find the most similar part to these models from the input images
to detect the position.

The correlation value showing the degree of similarity, measurement object
position, and inclination can be output.

• When identifying the shape of measurement objects (for detecting defects

or foreign matter)
