Small component (around 2mm x 1mm) measurement

Thickness Measurement on friction Stays

One station of the friction stays automation is detecting the thickness and two gaps using CCD with the back light.

The algorithm using the binary cut technique with the edge filter is stable in easily ROI setting parameters.

A gap length detector from the top view of multiple types

To detect the friction stays gap length, some locating and clustering methods are used with simple setting factors.
The effect is shown below:

A heavy scratching detector (AUTO ROI with spotlight)

This is a heavy scratching detector.

I implement the detector using the gabor filter and certain binary cut technique with a template.

The gabor filter kernel and the template:

Light Scratching:

Another hole detector

Detect the focus area by light, find the hole with the low gray limited in the hole boundary range.
