@hopalong In camera AI config UI, enable option for "Only for confirmed vehicles alerts"

Toggled it and will report back. Thanks.

Lots of cars have come through and still nothing in the AI Tab.

Could the greyed out Use GPU be causing issues? Not sure how to get it unchecked.

I also noticed that the YOLOv5 is doing the identification in the logs and not the ALPR:

One more thing I just noticed is the clips are tagged in the UI3 interface:

So, I am able to see the license plate detection work when I play back videos with cars in them now! Woohooo... Onto getting the MQTT reporting going.

Anyone have any instructions on publishing a MQTT message with the plate number and confidence?

What is interesting to me is when I click the "use custom models", it is blank for me. I tried rebooting the AI and Blue Iris itself.

Still not seeing stuff in the AI tab after tweaking the settings per @actran suggestion. =\

@MikeLud1 - I can confirm that the CPU version of ALPR works better than the GPU version for detecting plate numbers.

I have two BI computers running the exact same settings. In CPU mode, I get plate numbers. In GPU mode I rarely do. This seems strange because the processing should be the same.

@hopalong You need to hold down the Ctrl key and double-click on a thumbnail in the main alert window on the left. Did you try that?

That's the ticket. Thanks!

Thank you, I was going to suggest the long way, from what I was learning, it was a length process, open the log, copy the dat file in the box, you saved me hours, thanks for the tips.

My AI is reporting "DayPlate" but not reporting any of the numbers. Get an error on that..

AlphaBlueIris · Mar 10, 2023

It is funny you mentioned it, i occasionally I get a plate number but other times, dayplate 90% without the plate number associated with it. I think it works like magic....

Maybe it just can't read Massachusetts plates...

That's interesting I am going to test and see if I am getting the same results. One question are you using main stream for both CPU and GPU.

Yes.

I ran some tests and I am not see any difference in accuracy between CPU or GPU only slower detection times for CPU.
What CUDA version do you have installed, it should be CUDA 11.7.

CPU

GPU

JNDATHP · Mar 12, 2023

@MikeLud1 Looks like 12.0 yet it was a fresh CUDA install by CPAI.

CP.AI does not install CUDA, you need to install CUDA first then CP.AI. IF CUDA is installed after CP.AI the correct Python modules will not be installed
Try running nvcc --version in a command prompt and see what version show then

Hey,

Any one got this working on UK Plates?
