Counting of Integrated Circuits by photo or video

In summary, the counting of integrated circuits using photo or video methods involves capturing images or footage of circuit boards and utilizing software algorithms to identify and quantify the number of integrated circuits present. This approach enhances accuracy and efficiency in inventory management and quality control processes, reducing the need for manual counting and minimizing human error. Advanced imaging techniques and machine learning models can further improve the precision of the counting process.

TL;DR Summary
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?

Welcome to PF.

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?

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.
 

FAQ: Counting of Integrated Circuits by photo or video

What is the process of counting integrated circuits using photo or video?

The process typically involves capturing high-resolution images or videos of a batch of integrated circuits. Image processing techniques are then applied to identify and count the individual circuits. This can include filtering, edge detection, and pattern recognition algorithms to accurately distinguish the circuits from the background and each other.

What are the advantages of counting integrated circuits using image processing?

Counting integrated circuits through image processing offers several advantages, including increased speed and accuracy compared to manual counting. It also allows for the processing of large quantities of circuits quickly, reduces human error, and can be automated for efficiency in manufacturing and quality control processes.

What types of image processing techniques are commonly used for counting?

Common image processing techniques include thresholding to separate the circuits from the background, contour detection to outline the shapes of the circuits, and machine learning algorithms for more complex identification tasks. These techniques help in distinguishing overlapping circuits and improving counting accuracy.

How do lighting conditions affect the counting process?

Lighting conditions play a crucial role in the accuracy of counting integrated circuits. Poor lighting can lead to shadows and reflections that obscure the circuits, while excessive brightness can cause glare. Optimal lighting conditions are necessary to enhance image quality and ensure clear visibility of the circuits for accurate counting.

Can counting integrated circuits by photo or video be done in real-time?

Yes, counting integrated circuits by photo or video can be done in real-time, especially with advancements in image processing technology and faster computing power. Real-time counting allows for immediate feedback during manufacturing processes, enabling quick adjustments and quality control measures to be implemented on the fly.
