What are good algorithms for vehicle license plate detection? [closed]

Answer 1

I would suggest using a service or third party for this. Open ALPR, provides an open source package that is very accurate for this service.

Open ALPR - https://www.openalpr.com/

Or you could use an API -

Macgyver Computer Vision API

https://askmacgyver.com/explore/program/license-plate-recognition/3X5D3d2k

In this API you would simply make a post request to -

https://macgyver.services

Example Payload

{
id: "3X5D3d2k",
key: "free",
data: {
    "image_url": "https://storage.googleapis.com/marketing-files/program-markdown-assets/license-detection/license-plate.jpg",
    "country": "us",
    "numberCandidates": 2
  }
}

The image above would return the following -

"plate": "284FH8"
"confidence": 90.601013
