<![CDATA[UnitV2 OCR - License Plate Recognition]]>Hello,

I need to make the UnitV2 to recognize/read car plate numbers so I can open the street barrier with arduino relay. I am not sure how to achieve that, as beside opencv I need ocr libraries and other utils which are not coming pre installed. I would love to see any hints from anyone that implemented OCR projects with this unit

Thanks

I have a UnitV2 (and the older UnitV) as well but only little experience with. My approach would be the following:
To recognise only a few well known vehicles you can classify the image of the whole plate including car front (and drivers face) instead of the individual numbers/letters on it. This can be done with the V-training or with the online classifier function.
For recognising single numbers/letters you can try to classify individual numbers/letters and then "read" the x-coordinates of the returned boundary boxes in ascending order to convert into string and then compare to a list/database.
