I think I've installed everything correctly, my camera's are set up to get great images of license plates in day and night... but I have no idea where to get the list of what plates it's captured or to see if it's working correctly. I MUST be missing a step.

When I used platerecognizer.com - I got a list of all the plates it captured. I'm trying to switch from using that to using codeProject.ai / license plate reader - or to use some kind of combination so that only 1 good image per plate gets sent to platerecognizer... or something... bottom line, I need a list of plates it finds, hopefully with a picture of the plate. Hoping you guys can figure out what I'm missing here... Please help! :)

Examples of the plates I'm capturing:

Day-Plate.jpg

Night-Plate.jpg

I have Blue Iris installed and working well.

I have installed CodeProject.AI

I have added "License Plate Reader" to CodeProject.ai

It appears as though it is working looking at the CodeProject.ai logs:

I have configured BlueIris main setup AI tab to use AI Server / Code Project:

I have configured my LPR camera AI for code project (I think)

@jeremycolvin Assuming you are on a recent release of BI5 and CP.AI, for first screen, turn off "Default object detection" and turn ON "ALPR for Plates"

For 2nd screen, this worked for me:

Also, just fyi, I have tried with both "Use GPU" checked and unchecked. I have plenty of system resources (128 GB ram and a NVidia GeForce RTX 4090 GPU, so either using CPU or GPU should be fine. With 15 cameras my blue iris is using about 18-30% CPU and 7.4 G or memory.

@jeremycolvin

#1: What BI5 version? What CodeProject.AI version?

#2: In CodeProject.AI, click on Explorer, there is a Image tab for "License Plater Reader", upload an image and see if that works.

#3: In BI5, hold down Ctrl and double-click on a thumbnail on left. What do you see?

Try testing the ALPR module like show below.
Also what CUDA version do you have installed? You should be using CUDA 11.8, not CUDA 12.x. FYI a 4090 was use in the below screenshot

I think you may want to hide your Plate Recognizer key.

@jeremycolvin Take your original image and crop it to smaller area around license plate. Upload modified image to the above manual test again.

BTW, you're on the latest BI5 and CP.AI so that should not be issue.

The image he tested should of worked. I think the issues he is having is because the wrong version CUDA is installed.
