Detailed Explanation of AOI Algorithm - Missing Algorithm

2025-06-23

Among the over 20 algorithms of the AOI(Automatic Optical Inspection Instrument) of Shenzhou Vision, there is one algorithm called the Missing algorithm, which is a specific image processing algorithm for missing components of capacitors. It determines and detects whether there is a missing component in the electrode by comparing the area difference between the external rectangles of the two electrodes of the standard capacitor and those of the two electrodes of the capacitor to be tested. As shown below:

A Detailed Explanation of the Aleader Algorithm - The Missing Algorithm

The above figure is a schematic diagram of the components when a Missing component occurs. ① represents the outer rectangles of the two highlighted electrode regions at both ends of the normal component, and ② represents the outer rectangles of the two highlighted regions at both ends when a missing component occurs. Then, the difference values under the missing algorithm are as follows:

Result = (S2 - S1)/ S1 – 1

Here, S2 represents the area of the circumscribed rectangle B, and S1 represents the area of the circumscribed rectangle A.

Hint: The default determination range of the Missing algorithm is (0, 15).
