Full ALPR Database System for Blue Iris!

[algertc]

Okay, I've found the issue and adding it here in case someone runs into this in the future. On this system, I was still running the older 0.18 code and when I upgraded to 0.19, it fixed the problem partially. It seems in newer versions of BI (certainly in 5.9.9.73, but NOT in 5.9.9.33), the AI handling was changed slightly.

Essentially, if you have object detection enabled at the BI main settings, and even if you did not enable it on a camera, it is still do it, and the results will be sent via the &JSON macro. In 0.18 of the ALPR Database, it would result in the error above, but in 0.19, it handles it fine. If you have BI burn the detection into the image, you will see:

The fix is:

1) Upgrade to 0.19 of ALPR Database, and/or
2) On BI, turn off object detection at the main settings menu, and maybe enable it the individual camera if you need it, but not on your ALPR camera.

Like you mention, and I say in that GitHub issue, I made changes that seem to fix part of this in the last update. Seems like I still need to make the parsing more robust. It’s the multiple plate numbers in one image part that makes it a bit tricky. Shouldn’t be hard to fix though.

If you could paste the AI_dump that causes the issue, that would be very helpful.

Sure, how do I get the AI_dump data?

Maybe try adding an email alert with &JSON and see if you can email it to yourself. I think that should work.

It won't expand &AI_dump, it just literally prints that text, whereas &CAM will expand it to the camera name. I didn't go back to older versions of BI nor ALPRdatabase, this is with 0.19 and 5.9.9.73.

I have been working on a totally new ALPR module based on YOLO11. I have been running in parallel with the current ALPR module and I am see better results, below is one example that the old ALPR could not read the plate also Plate Recognition could not read the plate. The new module are using all ONNX models that I trained. The ONNX model are fast and can work on Intel iGPUs. This new module I am planning on adding vehicle color, make model and also State recognition . I am think of creating a patch for CP.AI that will allow users to install new module using a GitHub link

Can't Wait to test this out.

It's because the macro is called &JSON in Blue Iris. AI_dump was just my random name for it within the app.
