|

|
||||
|
||||
### 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
|
||||
sh tools/run.sh
|
||||
./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
|
||||
# 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。
|
||||
* 更多地，tools/config.txt中的参数及解释如下。
|
||||
更多参数如下：
|
||||
|
||||

|
||||
|
||||
* 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。

### Run the demo
|
||||
* Execute the following command to complete the OCR recognition and detection of an image.
|
||||
|
||||
Execute the built executable file:
|
||||
```shell
|
||||
sh tools/run.sh
|
||||
./build/ppocr <mode> [--param1] [--param2] [...]
|
||||
```
|
||||
Here, `mode` is a required parameter，and the value range is ['det', 'rec', 'system'], representing using detection only, using recognition only and using the end-to-end system respectively. Specifically,
|
||||
|
||||
##### 1. run det demo:
|
||||
```shell
|
||||
./build/ppocr det \
|
||||
--det_model_dir=inference/ch_ppocr_mobile_v2.0_det_infer \
|
||||
--image_dir=../../doc/imgs/12.jpg
|
||||
```
|
||||
##### 2. run rec demo:
|
||||
```shell
|
||||
./build/ppocr rec \
|
||||
--rec_model_dir=inference/ch_ppocr_mobile_v2.0_rec_infer \
|
||||
--image_dir=../../doc/imgs_words/ch/
|
||||
```
|
||||
##### 3. run system demo:
|
||||
```shell
|
||||
# without text direction classifier
|
||||
./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
|
||||
# with text direction classifier

|
||||
|
||||
* If you want to orientation classifier to correct the detected boxes, you can set `use_angle_cls` in the file `tools/config.txt` as 1 to enable the function.
|
||||
* What's more, Parameters and their meanings in `tools/config.txt` are as follows.

* 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`.
