# paddleocr package使用说明

## 快速上手

### 安装whl包

pip安装
```bash
pip install paddleocr
```

本地构建并安装
```bash
python setup.py bdist_wheel
pip install dist/paddleocr-0.0.1-py3-none-any.whl
```
### 1. 代码使用

* 检测+识别全流程
```python
from paddleocr import PaddleOCR, draw_ocr
ocr = PaddleOCR(model_storage_directory='./model') # need to run only once to load model into memory
img_path = 'PaddleOCR/doc/imgs/11.jpg'
result = ocr.ocr(img_path)
for line in result:
    print(line)

# 显示结果
from PIL import Image
image = Image.open(img_path).convert('RGB')
boxes = [line[0] for line in result]
txts = [line[1][0] for line in result]
scores = [line[1][1] for line in result]
im_show = draw_ocr(image, boxes, txts, scores, font_path='/path/to/PaddleOCR/doc/simfang.ttf')
im_show = Image.fromarray(im_show)
im_show.save('result.jpg')
```
结果是一个list，每个item包含了文本框，文字和识别置信度
