Hi,

I'm currently trying to detect licence plate from the video stream of my webcam, using the Python ALPR Api. What I am doing for the moment, is using OpenCV to extract a frame from the video stream, and then use it with OpenALPR.

My question is : Is it possible to directly use the video stream from my webcam as an input to OpenALPR (just like with the command lines) ? Instead of taking pictures from the webcam ? Because i guess that ALPR works better with a video stream than just static pictures.

"alpr webcam" should read from your webcam (assumes /dev/video0). alprd can also use a webcam.

Thanks Matt for you answer.

My question is, how to do the same using the Python API ? I don't want to use the command lines ...

Probably using the OpenCV API to pull from your webcam and then sending those images to OpenALPR would be the easiest. Here's a helpful tutorial:
