# PaddleOCR
## 模型介绍
基于百度PaddleOCR的字符识别模型。
## 论文
det、rec、cls三个模型的backbone基于mobilenetv3,可参考mobilenetv3的相关论文
https://arxiv.org/pdf/1905.02244.pdf
## 模型结构
整体包含检测和识别两个模型。

## 训练及推理
### 环境配置
## 环境配置
在
[
光源
](
https://www.sourcefind.cn/#/service-details
)
可拉取训练以及推理的docker镜像,在
[
光合开发者社区
](
https://cancon.hpccube.com:65024/4/main/
)
可下载paddle安装包。PaddleOCR推荐的镜像如下:
```
docker pull image.sourcefind.cn:5000/dcu/admin/base/paddlepaddle:2.3.2-centos7.6-dtk-22.10.1-py37-latest
