I'm using absdiff which isn't all that robust. That's why I have a fixture to ensure each PCB will be in the exact same position. I have a 2nd version that doesn't need a fixture and automatically rotates the PCBs to be in the same position but its defect detection is more noisy. Thanks for asking!
This will work with any PCB that has a square or rectangular shape. Although I don't think it would take much to allow for this to work for any PCB shape. Thanks for the idea!
I'd like to use computer-vision + AI, to inspect Printed-Circuit-Boards.. How does training a model on good / bad examples, compare to tools that run out of the box, like KollerFacts Inspection, Intuitive Machines Defect Detection, SVI Defect Analyzer, Cyient Inspection, Mentor Tessent YieldInsight Also how does PCB-Defect-Detection (YOLOv5, RNCC, etc) compre with PCB-Inspection-OpenCV?
That's a great question. The overlay feature allows you to see a ghost image of the reference board so you can align them pretty well. However there is still room for human error in the manual alignment. I have a new version that uses image registration to automatically align the reference and inspection images. But it's a work in progress. Maybe it's time I upload another video!
@@jared-horton Oh ok - so its work in progress :) - i thought there are some reference points and so on that the image could be scaled and aligned to.. I dont get what do all these intersecting gear lines do (saw-lines)
The gears are part of a fixture mechanism that I intended to use to hold the pcb in a certain position. The fixture can fit any sized rectangular PCB. But now that I have auto alignment implemented, I can get rid of the fixture
I'm glad you find his project interesting! It uses a microscope camera. I believe this camera cost ~$300 but you could get a better camera for cheaper. I haven't made this into a product since its not robust enough, but the idea interests me
Very good result, please I'm working on the same topic of my end of study project, and I’m really stuck, can you share the code with me, otherwise just some tips can be enough to direct me to the solution. please, If you could help me, I would be so grateful.
Hi Jared, Very Good and Knowledgeable project. Could you share the want kind of resource you used. Like ..which camera and its specification and other stuff...like that...Thanks🙂👍👍👍
I used a microscope usb camera with a C mount lens. This kind of setup is very common for PCB inspection, but unfortunstely they can be expensive, around $300 but you can find cheaper ones with great quality for around $200 on Amazon. Glad you enjoyed it!
Hi Jared, Very good work. Do you have a gitgub-Repro for that or a documentation how you did the detection with OpenCV? Thanks.
Would love to know what kind of method is used is finding the difference between two images thresholding? Edge detection? Absdiff?

@@jared-horton thanks for sharing. Appreciate it👍👍👍
hey Jared Horton, please do this machine support all pcb or there's any specification?
thanks and interesting vib

Really interesting project, nice demo!
Hello Jared, where can i find the code?
Hello, what type of camera are you using?
Hi Jared,
Fantastic !
Would it be possible to share the content of the project?
What camera is that?

Hi Jared,
great work!
I am struggling with the picture distortions.
Is your code available anywhere?
Hello. Can you share the CODE of this study. I would like to make additions or updates for educational purposes.
Good work! thanks, but how do you cope with misalignment/rotations? Do You?

I would love to buy one of your inspection devices. How much does it cost to make?

Hello. Can you share the CODE of this study? Nice Demo
Can this be used for pcb bare board testing aswell?
Yep!
Sir can u pls upload a full video and detailed explanations
Can u share the code plzz
Can u please share the code
no code ? cmon
