Hello Team,

PaddleOCR works out of the box on the printed texts on labels and receipts. But I have an issue in doing OCR on this simple image. Can you please let me know what could be the issue with this image?

This is the result I got:

text: NERPI6IZLIL -------------- scores: 0.4638494551181793
inference time in ms: 92.56663499763818

you need to fineture you det model.

检测的问题，det boxes: [[152,174],[376,163],[378,207],[154,218]]rec text: NERPI6IZLIL rec score:0.463844 cls label: 0 cls score: 0.947102。把两行检测成一行了。所以识别错误了。需要重新训练检测模型。

Hi @shiyutang , Should the detector model alone be finetuned or the recognition model as well?

[shiyutang]

The problem is with the detector model.
