Thanks for posting the link. I went through it , but I think that is just related to the ALPR part, not BI. I think BI is not sending any ALPR requests if it doesn't find a License Plate throught the custom model. I suppose then, that it could be just necessary to untick vehicles detection in BI to have ALPR processing everything.

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

i'm pretty sure i've tried these ai tab settings.. one question, shouldnt save recent images be set to a folder? what does this plugin do when it grabs a plate otherwise? what should be occurring if its working?

Mike, I didn't notice anything unusual, there were 2 Intel driver updates, one of them appear to be a video driver update based on the version numbering--but the running system currently shows an older
driver (32.0.101.6881) vs the updated one in system history (32.0.101.7026). It's been working fine since. Maybe it's just a Window's thing.

Thanks!

Mike,

It crashed again today. Looks like it's triggered by windows update, one of these 3 components:


Is anyone else getting these updates and survive them?

Thanks

It looks like the iGPU driver was updated, my new modules use the DirectML which is part of the iGPU driver. There is nothing to stop the crash if the driver is updated.

isnt part of the setup to make this work, setting the alert to not just goto the database but also to a jpg? (i've done that and followed the screen shots for each section but i end up with nothing, if i turn back on custom objects and set things the way i had them, i get a car/plate every single time as an alert just not with the plate letters and numbers in the border square)

Maybe it's a failed update? Because it's the same driver version as the last time.

What's the difference between the .NET and the ONNX LPR Modules?

A small note for those who upgraded already to V6 . It seems that the new BI calls /v1/image/alpr, not /v1/vision/alpr ... so be advised. Just set the correct route inside the module settings, or ALPR won't work.

Not sure which module settings you are referring to, but I didn't change anything and mine is still working with V6.

I've changed the module settings.json in this section :

"RouteMaps": [
{
"Name": "License Plate Recognition (YOLO11 .NET)",
"Route": "image/alpr",
"Method": "POST",

I've used WireShark to capture the BI API call to CPAI and found out that BI was calling image/alpr (that resulted in a 404 error) , while the explorer was calling vision/alpr (that was working) .

Before I reverted back to the older versions. I did just as you describe. I can try it once again, but there is no reason to suggest that it would start working now.

Happy New Year.

Not sure if you got problem resolved. I had exactly the same issue (no trigger from CPAI, but OK manually), and got it fixed with steps below:

1. Uninstall CPAI.
2. Removed both CodeProject folders in “Program Files” and “ProgramData” (this folder is hidden).
3. Reinstall CPAI with ALPR 3.3.4 and Object Detection YOLOv5.6.2
4. Confirm CPAI is running.
5. Stop CPAI service.
6. Copy new app settings.json.
7. Restart CPAI service.
8. Stop ALPR 3.3.4 and Object Detection YOLOv5.6.2.
9. Install LPR YOLO11.NET.
10. Install Object Detection YOLO11.NET (Optional).

I think step 3 is important. I had installed CPAI with no module prior to copy new json file, and BI could not trigger CPAI.
