Counting of Integrated Circuits by photo or video

Click For Summary
SUMMARY

The discussion focuses on methods for counting integrated circuits (ICs) in anti-static shipping tubes using photo or video technology. Participants suggest exploring machine vision systems from manufacturers like Cognex, Keyence, and Omron, which can automate the counting process. Weighing the ICs is also proposed as an alternative method. Additionally, users recommend utilizing MATLAB functions such as strel(), imerode(), and bwlabel() for image processing to enhance counting accuracy.

PREREQUISITES
  • Understanding of machine vision technology
  • Familiarity with MATLAB image processing functions
  • Knowledge of weighing methods for counting
  • Basic concepts of mathematical morphology
NEXT STEPS
  • Research machine vision systems from Cognex, Keyence, and Omron

TL;DR
Counting of Integrated Circuits by photo or video
I am looking for a quick, cheap yet reliable way to count IC's that are in anti-statis shipping tubes. I am thinking of a way to count automatically via a photo or video?

Can you post a few representative photos? Use the "Attach files" link below the Edit window to upload the images.

Have you considered using weighing instead of photo/video?

There's a counting app in apple store. You can probably try before you buy.

It's almost a trivial task for new AI, I reckon.
 
Search machine vision. This should be a near trivial task for a modern machine vision system. There are a number of good machine vision manufacturers that can supply a good and reliable system. Just do not expect it to be cheap.

Are they all the same. If so, can you weigh them?

currently looking at using a laser sensor to count the pins on the IC
 
As someone suggested, you should look into machine vision. You should be able to achieve exactly what you're looking for via "cameras" / sensors. Some brands to take a look at - Cognex, Keyence, Omron.

I wouldn't suggest this as an accurate way unless you really put a lot into your own code, but I wanted to share maybe a crude fast way if you know roughly which shapes you are looking for you can use mathematical morphology on a tool like matlab or (free) imagej. On MATLAB i'll use something like strel() and imerode() followed by bwlabel() https://www.mathworks.com/help/images/ref/bwlabel.html

When I look at packages usually ICs are much bigger than passives like bypass caps so I would make a rectangle or diamond that's slightly bigger than the passives and you might be able to get away with that.
