Any idea why I need to use license-plate?

It looks like CP.AI is not working. Reboot your PC then run this test image to see if CP.AI works

Anyone else experiencing memory leak with the ALPR module?

Hey @MikeLud1 Is there any way that I can train the licence-plate model to work a bit better with Australian plates? Although in saying that I've got no clue how but willing to learn.
I've just started running @algertc database system for ALPR which is brilliant way to view things in an organised fashion and whilst your model picks up most plates it seems to get a bit funny with some.. please note a large majority of the plates are correct and it does an amazing job and I am purely wanting to help potentially improve things if I can help at all. Here are some examples

First one, some plates in Australia (In the ACT) have a euro design.

Standard European style numberplates must start with the letter 'A' then a space which contains the ACT crest and bluebell logo, then a combination of 6 letters and numbers following the standard ACT 'Y' series format.

Here is one below going past my camera:


Unsure what happened with this and how it got TEET lol:


A few of the slim-line plates seem to get picked up with an "E" at the start like below I've noticed as well:

Yes and like you I tried to keep it under control using an automation, but I found a better way through BI. Under the AI settings in BI there is an option to restart CPAI every x number of minutes. I set mine to 720 (every 12 hours) and it works great.

ALPR seems to be working, just not with my plate capture. Do I need a better camera? Although, it was working a few iterations ago.

I ran your images through my setup with the same results. I think you've just got a bad angle on your plate captures.

Is that the mainstream? May wanna remove the BI timestamp as that is right in line with potential plates.

 

[JNDATHP]

I forgot to remove the timestamp after I deleted and re-added the camera. Thanks.

Thanks. This will certainly help someone out there! I'm not using Windows for my CodeProject.AI so this won't work for me, unfortunately.

Since there is a CORAL.AI object detections, how difficult would it be to port the ALPR to use the CORAL.ai multiple TPU?

When I use CPAI Explorer, am I using ALPR analysis on my computer or is it using the cloud? In other words, if it works in CPAI Explorer should it also work in BI?

It's using your CPAI configuration.

Thanks.

Interesting troubleshooting:

Original test image.





Test image cropped.





Test image rotated.




I am confused.
