EC Circle Search
This processing item searches the input image for parts having a high degree of similarity to the target circle
mark (model), and measures its circle evaluated value (similarity) and position. In a normal search, image
pattern models are used that look at the color and light/dark information. In EC Circle Search, however, models
are used that look at the profile. Therefore, this processing assures a reliable search even for low-contrast or
noisy images. It is also possible to measure the number of circles in the input image.
Used in the Following Case
• This counts how many circles there are of the specified size. Since circles are extracted with
the shape information of "Round", the circles being deformed or dirty does not affect
counting.
• Processing is different for color images and monochrome images. If the camera type, color camera, or monochrome
camera, was changed from a previous setup, a reset of some settings may be needed.
Example) Quantity count
Circular forms are counted as one piece even if deformation or
internal contamination is present.
The range of permissible deformation can be changed.
