New CodeProject.AI License Plate Recognition (YOLO11) Module

I have a pretty old CPU. Not sure if this will work for me. I have the app quitting..


Will this work with one of the cheap Intel Arc Graphics cards?

Im confused, cant quite get plate recognition to work though manually testing jpgs seems to.. (so far testing at night)

Which of these do i want for objects (just v5 with the yolo 11?) i have them all as of now

1763854590188.png1763854628389.png

If i manage to get a trigger (nighttime), where it saves an alert, i show "DayPlate" as triggered (but not car), if i run the exported jpg through the software on the server webconsole i get..

"No predictions returned" but you can clearly see the lit plate, though half the car is above the frame due to the angle i have the camera.

If you read back through this thread (pretty sure it's this one) you'll see the answers to your questions. I had the same. Turn off the custom object models and all that to confirm stuff.

You do not need the custom model, use the below AI settings.

Thanks, i've retooled those areas to match (though so far nothing has worked), might be my motion settings, unsure, or dark is just tough (I just watched a van go by that should have been detected then the plate, but no alerts got triggered):

1763858628909.png

EDIT: i think it didnt get triggered at all because of unchecking custom object models, when i played the clip using the ai detector tool overlay, nothing was found (squares are there but no objects at all, the plate was lit up and bright for a good 3-4 seconds)

That didnt help in terms of it decoding plates.

I never see an alert unless i have the custom objects on.

And the last test i did, i saved a jpg of myself going past the camera in the dark, 3-4 sec of clear shots of plate, on one i exported it and did the decode test and it did largely get it right, the first letter was wrong.
But in all my testing, im assuming there should be text files with the plate numbers that are decoded as designated by the save plates checkbox correct? I never see anything

I assume this is all correct :

Example debug code here tonight 846 i can see the plate on a car going by, and in the debug:
20:46:28:Response rec'd from Object Detection (YOLO11 .NET) command 'custom' (...e69dcf) ['No objects found'] took 583ms
20:46:28:Response rec'd from Object Detection (YOLO11 .NET) command 'custom' (...f57100) ['No objects found'] took 799ms

20:46:29:Response rec'd from Object Detection (YOLO11 .NET) command 'custom' (...ea9c00) ['No objects found'] took 1402ms

Shows as DayPlate (even though night time), but nothing decoded in the folder to save "license plates" etc
And nothing to indicate trying to decode

One weird thing, i seem to have my license plate saved at C:\Program Files\CodeProject\AI\modules\ALPRYOLO11NET from my test drive past the cam at 830pm

Not sure how or why? (i did just enable debug mode , maybe related)

Did you make all the changes that is shown in the below post. Do not use the camera you want to capture license plates for any other Object Detection, if needed clone the camera for Object Detection.

Yea I had tried those settings. Nothing ended up in the plates folder

Yeah i've ran those tests and gotten results before.

I just dont seem to get anything generated from the plugin. What should it ultimately being doing if its working, putting a jpg with a close up of the plate in the "Plates" folder, along with the file name being the plate name or? (this has yet to happen even on setting things exactly as the steps show).
