Hi,

for a new project, I would like to know if it is possible to recognize even skewed number plates.

For example:

With the getplate demo the plates get not recognized, unfortunately.

Thank you in advance!

Kind regards

Andreas

Hi Andreas

IEVision uses OpenCV for number plate recognition, so unfortunately we are limited to what that library provides.

Hi Nigel,

is there something I can do to improve results? Such as blackhat morph or is it already implemented in the current version?

Kind regards

Andreas

Hi Andreas

I'm not aware of any automated optimizations, only manual selection of the recognition area.

Hi

*** 2024 UPDATE ***

The latest version of ImageEn is likely to give you better results, by either:

- Finding the text rects using a neural network (and then passing them to the OCR engine, which now works better with oriented text)

- Parsing the image using Google Vision API
