AI setup help for ALPR

[GI0UTE]

Congrats on getting it dialed in. Excellent images. Based on your post, I understand this is turning into your driveway and also upon leaving.

Are there special settings that you use on the camera? Thank you in advance.

Thanks for your feedback. The camera is setup as per the recommendations in the YouTube video I linked in my first post here. I have made some site specific adjustments from there, but the camera "just works", which suits me. I can definitely recommend it for this use.

Oh and just to add, the camera is looking down my lane focusing on 100 to 200 feet out. Seems the sweet spot for this camera and my setup. I have other cameras that give a more wide view to pick up on vehicle type and colour, people and animals etc. Hope that helps?

I'd rather use Plate Regocnizer instead of CodeProject's ALPR. Where CP's performance for me turned out to be a big disappointment, Plate Regocnizer;s results are phenomenal.

For object detection in BI I started using CodeProject for a short while but immediately saw better performance with DeepStack. CP saw our labrador for a bear - which I find a gross insult - and a worn out red/brown door for a fire hydrant, DeepStack didn't come with any of that nonsense.

That's interesting . I haven't used plate Reckonizer or deep stack but I guess models will improve over time. With CPai I do get some interesting suggestions on occasions for animals etc, but nothing is perfect. Using AI has massively reduced false alarms for me Vs" the old way" which ment on a windy night I just had constant alarms, or I would tune down sensitivity to a point where you could walk past a camera and not trigger it. It's all progress.

Because your footage is near perfect, you won't be disappointed, but try from a different angle, or from a bit greater distance and CodeProject fails, while Plate Recognizer gets results even from an angle where you can hardly see it yourself anymore:

Try disabling ORC optimization to see if that helps reading the full plate. I add that option to help read the US plates that have narrow fonts.

Disabling OCR Optimization didn't help, but what did was disabling Auto Plate Rotation.
