No value in OCR tag

[svenny71]

Hi faisalthaheem,

I'm testing your software and I'm not able to get a result in OCR tag of JSON response:

curl -F "[email protected]" localhost:5000/process

{"_id":"a0cfe6f7-4b99-4cf3-94a8-7992a4f5ae4f","creationtime":1655916903.771078,"detections":{"boxes":[[164,128,490,245]],"classes":[2],"scores":[0.9779990911483765]},"filename":"XK50HF.jpg","imgDimensions":{"channels":"RGB","height":665,"width":387},"ocr":[],"unique_name":"a0cfe6f7-4b99-4cf3-94a8-7992a4f5ae4f_XK50HF.jpg"}

I've tried a lot of images, but always get the same results.

Many thanks in advance for your response.

Cheers,
Svenny

Hi, and thanks for your reply!

These are 3 images I used for testing:

1. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcS-ekWNXtXQuXGI4hGKlp5B3-VECUJL5FPWnw&usqp=CAU
   OCR tag empty

2. https://media.istockphoto.com/photos/classic-mercedesbenz-sl-450-with-a-brexit-plate-parked-in-a-street-in-picture-id1132133984?k=20&m=1132133984&s=612x612&w=0&h=8IAUrPv5zlc6Qgnpj-77gGuXga7RfTsjaCycAaz9tMM=
   OCR tag empty

3. https://www.periodicoitaliano.it/wp-content/uploads/2022/04/targa-ZA.jpg
   OCR tag is "ZA" only (second row is not read). If I remember correctly, two lines plates were recognized by the demo some days ago.

I've tried to upload those images on your demo, but it always timeouts now.

All images I have tested come from the web, probably they're not so good for this purpose...

Thanks!

Cheers,
Svenny

Hi Mr. Faisalthaheem,

I am facing the same issue, OCR is empty. Would it be because the model is not specified?

I had to reduce the confidence to 0.5 the ocr.yaml file of the open-lpr-ocr-1 container to start to get OCR results.
