# PaddleOCR 模型部署
|
||
|
||
## PaddleOCR为多个模型组合串联任务，包含
|
||
- 文本检测 `DBDetector`
|
||
- [可选]方向分类 `Classifer` 用于调整进入文字识别前的图像方向
|
||
- 文字识别 `Recognizer` 用于从图像中识别出文字
|
||
|
||
根据不同场景, FastDeploy汇总提供如下OCR任务部署, 用户需同时下载3个模型与字典文件（或2个，分类器可选), 完成OCR整个预测流程
|
||
|
||
### PP-OCR 中英文系列模型
|
||
下表中的模型下载链接由PaddleOCR模型库提供, 详见[PP-OCR系列模型列表](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/doc/doc_ch/models_list.md)
