If you use IR camera the retro reflective plates will aid with the OCR performance and give a higher confidence. Also if you train an OCR library, this will make the performance quicker on detection side of things and confidence levels.
Great! I want to build exactly the same thing but using a Jetson Nano. What I would do for the 'Q' problem is to submit two versions one with a Q and one with a O. And to know if it's a Q, O or 0 I would check what position is that character with the format, for example license plates can't start with a number in most countries... On a quick look for Australian license plate format I noted that there are many formats, in which case you may want to build a model to detect what the format of the license plate should be. I hope you can release the code soon
Hey mate! Thanks for the suggestion!! You're definitely on to something. The OpenALPR library which is what I used to convert the image to text tries to distinguish between Q, O, and 0. Just like you said, Australia has way too many variations in license plates (Victoria alone is already a nightmare). 🤞 Planning to release the code and tutorial in the next couple of weeks - I had to redo some of the code since some libraries were made obsolete between the time I recorded this and now.
Really cool! What NN architecture (model) do you use for number plate detection and optical character recognition? It would be very interesting to see your code!
Hi Geser! If you're interested, I just released a video that explains how to code the entire system. Code is on Github, too. th-cam.com/video/6xklN4iiA0Q/w-d-xo.html github.com/edgecate/ANAL
The only thing you’re missing is an IR filter and an IR Illuminating device of the same NM basically it reflects back only IR lighting into the cam and the computer can’t actually see the car it can only see the plate and outline of text

Amazing stuff Andrew! Great content and nice edits
Thanks, mate! 😀

I'll be releasing the full code and tutorial, soon :)

Dont police use infrared cameras?
Did VRE ever throw a captcha when testing?
VRE, as in VicRoads? If so, nope. I wrote a Post request and I guess it bypasses it.
Did you make the code public?
Amazing tutorial thanks. where's the code?
Thanks, dude! Planning to make it available, soon 😀
@@edgecate Thanks can you link us
I don't think openALPR is free.
