🔒 Validating license plate numbers

[outer pike]

Any idea how to validate if license plate numbers are valid numbers?
Also make sure to notice that each country has different license plate system

im using yolo to find license plate location and than OCR to get the text from it

But i dont know how could i validate if extracted text is actually the license plate number and not some kind of additional info from license plate like country car dealership etc.

probably query it against a public license plate database

[outer pike]

Is that possible with out knowing the country from which that license plate belongs to

Also i dont need that precise data

I just need to know which string fits correct schema

But there are like few hundred schemas of license plates

Eg here, thats license plate after few contrast changes to get better result from OCR

And in console i get that license number and bunch of useless data for me

How to validate that 2COOL4U is actually that license plate

Here is base photo which was used for testing

Also im using easyocr as my OCR system

Any hints are welcome

there might be some large global databases for this sort of thing

take a look

i already did that, and for sure i will do that unti l i find solution XD

validating the country/state is likely going to be the more difficult task than validating the plate

since you need to first know that this is a california plate

then you need to know the rules for california plates

Ye thats true

[minor beacon]

I think this is just about an impossible task

[outer pike]

Need to have array/map with all possible combinations of countries

Maybe i should go with different aproach

Then validating number

[jagged saffron]

next leetcode question

[outer pike]

XD

So im opened for any potential hints or solutions

[jagged saffron]

my best guess is find a relatively large database for this sort of stuff and then query that with a few hopes and prayers for a decently accurate result
