# PaddleOCR Model Deployment

## PaddleOCR contains a series of tasks with multiple models, including
- Text detection `DBDetector`
- [Optional] Direction classification `Classifer` is used to adjust the direction of images before text recognition
- Character recognition `Recognizer` is used to recognize characters from images

According to different scenarios, FastDeploy provides the following OCR task deployment. Users need to download three models and dictionary files (or two, optional classifier) simultaneously to complete the entire OCR prediction process 

### PP-OCR Model in English and Chinese Scenarios
The model download links in the following table are provided by PaddleOCR model library. Refer to [PP-OCR Model List](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/doc/doc_ch/models_list.md) for details
