New CodeProject.AI License Plate Recognition (YOLO11) Module

Happy to help and reduce the burden on Mike, looking forward to that ipcam-combined, this new license plate reader is amazing.

Edit: Not to derail things because this is working perfectly for me, but the number of inference report counts is wonky. I restarted CPAI so I could use Mike's new appsettings (working) but instead of starting at 0 it started in the 7000's which is where it was when I shut it down, and it didn't resume counting from there, it flips back and forth between low and mid 7000's until I triggered a plate reading and then it took 15 images and scanned them all and started flipping between three numbers, the actual count and the old counts.

I just did a fresh install of windows server 2025 and windows 11 pro. Just installed geforce drivers and runtime and SDK drivers also blueiris and codeproject ai. Still getting the same problem with the new 1.0.4 yolo11. Maybe I am missing something?

I just updated to 1.0.4 from 1.0.3 and yolo11 stopped working again.

I just released Version 1.0.4, this version uses the original v1.0.0 way of initializing the models using default GPU Device ID 0. One addition is now you can also manually select the GPU Device ID as before v1.0.0 was fixed to GPU Device ID 0.
If the GPU does not initialize due to incorrect GPU Device ID it should automatically fallback to CPU. Check Task Manager and lookup you GPU ID and then go to CodeProject.AI Dashboard and under GPU Device Selection select the correct GPU Device ID

OK, I tried starting from scratch again. I completed these steps in this order (as best I can remember):
1. Uninstalled all CodeProject AI modules.
2. Stopped CP.AI service.
3. Uninstalled CodeProject AI v 2.9.5 from control panel Programs and Features.
4. Deleted CodeProject AI folders in Program Files and Program Data.
5. Removed two CodeProject AI keys I found in Windows Registry.
6. Rebooted machine.
7. Installed CodeProject AI v 2.9.5 selecting only License Plate Reader v 3.3.4 and Object Detection (YOLOv5 .NET) v 1.14.0
At this point License Plate Reader v 3.3.4 was capturing license plate numbers
8. Replaced appsettings.json with new version.
9. Restarted CP.AI service and hit ctrl-F5.
10. Installed License Plate Reader (YOLO11-ONNX) v 1.0.4.
11. Stopped License Plate Reader v 3.3.4
12. Tried starting License Plate Reader (YOLO11-ONNX) v 1.0.4. Will not run.
13. Started License Plate Reader v 3.3.4
License Plate Reader v 3.3.4 is capturing license plate numbers

Can you post your CP.AI log file, sometimes iGPUs take some time to initialize

I rolled back to 3.3.4 and then updated to 1.0.4 and it started working again.

i am getting this when trying to install the new module "Error in Install ALPRYOLO11: Response timeout. Try increasing the timeout value"

This is the windows 11 pro fresh install. Let me know if you need anything else.
Thanks Mike

it says installed but now i get this error...

I even installed cuda and cudnn still same results.

Hey Mike,

I'm on 1.0.3, and I am seeing some issues with high confidence but the characters are in the wrong position. This sometimes happens with the previous code, but usually by plates where there is a space between the characters, and it happened very infrequently. This seems to happen a lot more frequent. I'm seeing it happen about 3% of the time.

Thanks
