 ## 安装
-### 1. 安装PaddleOCR
+### 1. 环境搭建
-PPOCRLabel内置PaddleOCR模型，故请参考[PaddleOCR安装文档](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/doc/doc_ch/installation.md)准备好PaddleOCR，并确保PaddleOCR安装成功。
+#### 安装PaddlePaddle
+```bash
+pip3 install --upgrade pip
+如果您的机器安装的是CUDA9或CUDA10，请运行以下命令安装
+python3 -m pip install paddlepaddle-gpu==2.0.0 -i https://mirror.baidu.com/pypi/simple
+如果您的机器是CPU，请运行以下命令安装
+python3 -m pip install paddlepaddle==2.0.0 -i https://mirror.baidu.com/pypi/simple
+```
+更多的版本需求，请参照[安装文档](https://www.paddlepaddle.org.cn/install/quick)中的说明进行操作。
+#### **安装PaddleOCR**
+```bash
+【推荐】git clone https://github.com/PaddlePaddle/PaddleOCR
+如果因为网络问题无法pull成功，也可选择使用码云上的托管：
+git clone https://gitee.com/paddlepaddle/PaddleOCR
+注：码云托管代码可能无法实时同步本github项目更新，存在3~5天延时，请优先使用推荐方式。
+```
+#### 安装第三方库
+```bash
+cd PaddleOCR
+pip3 install -r requirements.txt
+```
+注意，windows环境下，建议从[这里](https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely)下载shapely安装包完成安装， 直接通过pip安装的shapely库可能出现`[winRrror 126] 找不到指定模块的问题`。

 ### 运行demo
-* 执行以下命令，完成对一幅图像的OCR识别与检测。
+运行方式：  
+```shell
+./build/ppocr <mode> [--param1] [--param2] [...]
+```  
+其中，`mode`为必选参数，表示选择的功能，取值范围['det', 'rec', 'system']，分别表示调用检测、识别、检测识别串联（包括方向分类器）。具体命令如下：
+##### 1. 只调用检测：
+```shell
+./build/ppocr det \
+    --det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
+    --image_dir=../../doc/imgs/12.jpg
+```
+##### 2. 只调用识别：
+```shell
+./build/ppocr rec \
+    --rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
+    --image_dir=../../doc/imgs_words/ch/
+```
+##### 3. 调用串联：
 ```shell
-sh tools/run.sh
+# 不使用方向分类器
+./build/ppocr system \
+    --det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
+    --rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
+    --image_dir=../../doc/imgs/12.jpg
+# 使用方向分类器
+./build/ppocr system \
+    --det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
+    --use_angle_cls=true \
+    --cls_model_dir=inference/ch_ppocr_mobile_v2.0_cls_infer \
+    --rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
+    --image_dir=../../doc/imgs/12.jpg
 ```
-* 若需要使用方向分类器，则需要将`tools/config.txt`中的`use_angle_cls`参数修改为1，表示开启方向分类器的预测。

-* PaddleOCR也支持多语言的预测，更多支持的语言和模型可以参考[识别文档](../../doc/doc_ch/recognition.md)中的多语言字典与模型部分，如果希望进行多语言预测，只需将修改`tools/config.txt`中的`char_list_file`（字典文件路径）以及`rec_model_dir`（inference模型路径）字段即可。

-* Multi-language inference is also supported in PaddleOCR, you can refer to [recognition tutorial](../../doc/doc_en/recognition_en.md) for more supported languages and models in PaddleOCR. Specifically, if you want to infer using multi-language models, you just need to modify values of `char_list_file` and `rec_model_dir` in file `tools/config.txt`.

 Note: The above model is trained on the PubLayNet dataset and only supports English scanning scenarios. If you need to identify other scenarios, you need to train the model yourself and replace the three fields `det_model_dir`, `rec_model_dir`, `table_model_dir`.
