Problems running my software - Raspberry Pi being used


#1

Hello, and first may I say thank you for allowing me access to this forum.

I am trying to build the project described in https://randomnerdtutorials.com/car-plate-recognition-system-with-raspberry-pi-and-node-red/#comment-335263 and am using the following command in the cURL POST tab, sudo curl -X POST “https://api.openalpr.com/v2/recognize?secret_key=MY SECRET KEY&recognize_vehicle=1&country=eu&return_image=0&topn=10” -F image=@/home/pi/Pictures/car-photo.jpeg - I have replaced my actual secret key with the text MY SECRET KEY but when I run the programme the debug is as follows;

Could someone advise me as to why it is not reading the plate correctly and providing an output.

Many thanks is advance

Can you post your image where you trying to read the license plate from?

from a real license plate via the raspberry pi cam plugged into the raspberry pi

Thanks
