Blue Iris and CodeProject.AI ALPR

[carteriii]

Try the below settings

Ken did reply to my earlier message and it appears there was a change in BlueIris that changed the behavior for me to what it should have been all along. His explanation (below) also helped me. Obviously using the sample from @MikeLud1 worked, but I didn't fully understand how or why. I naively thought that objects:0 was preventing ANY model from running, but that only blocks the standard ones. Hopefully the explanation here will help everyone else as well.

"objects:0" just means to not use the STANDARD objects model. All custom models will be used unless you specify them individually.

Adding ,alpr will work ... this is not the name of a custom model, but its presence on the list prevents them all from being used. You could just put NO in that box (or anything else that's not the name of a custom model). This new behavior is the result of a bug fix, it's now operating as it should.

It looks like you have CUDA 12 installed, with your GPU you should be using CUDA 11.8. To confirm which CUDA version you have install open a Command Prompt are run nvcc --version then post a screenshot of the results, like the below.

Thanks again, Mike, for all your help.

It looks like it is either not installed in the path or CUDA is not fully present on this machine.

 

[Steve_Texas]

Some progress.

I downloaded CUDA 11.8 and installed it. I went to uninstall the LPR module and found that there was an update so I performed the update (3.0.3).

When it completed, the LPR module started as CPU only and crashed with a "failed to start" message about 5 minutes later.

I am going to try to uninstall / reinstall the LPR module and then reboot the system and try again.

After installing CUDA 11.8 did you run install_cuDNN.bat

 

[Steve_Texas]

Running it now, and as always, thanks, Mike. I really appreciate your help and patience.

You should really consider setting up an account on "buy me a coffee" (Buy Me a Coffee) so we can contribute to your java or brew fund!

 

[Steve_Texas]

Script ran with no errors. LPR module started, but as CPU and then crashed a few minutes later. Going to reboot the box and see if that changes anything.

If you shut your computer down and reboot 3.0.3 update should show up in the Install Modules.

To use the new Save Cropped Plate feature you need to create a new camera with the below settings

I just updated to the new LPR version and set this up.

Every time a car goes by, this ALPR "camera" restarts in BI and I get the plate image on the right, but nothing shows up in the alerts tab to the left - is there another box we need to check - like do we have to save jpg or video in BI?

Do you have the box checked in Blue Iris Settings that says "ALPR for plates?

Yes save jpg also have you ALPR camera trigger the new camera you created.
