安装

1. 安装PaddlePaddle

如果您没有基础的Python运行环境，请参考运行环境准备。

1
python -m pip install paddlepaddle==3.0.0rc1 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/

由于GPU端需要根据具体CUDA版本来对应安装使用，以下仅以Linux平台，pip安装英伟达GPU， CUDA11.8为例，其他平台，请参考飞桨官网安装文档中的说明进行操作。

1
python -m pip install paddlepaddle-gpu==3.0.0rc1 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/

2. 安装paddleocr

1
pip install paddleocr

NOTE: 可以通过设置环境变量 PADDLE_OCR_BASE_DIR 来自定义 OCR 模型的存储位置。如果未设置此变量，模型将下载到以下默认位置：

  • 在Linux/macOS上路径为：${HOME}/.paddleocr
  • 在Windows上路径为：C:\Users\{username}\.paddleocr

from paddleocr import PaddleOCR, draw_ocr

# Paddleocr supports Chinese, English, French, German, Korean and Japanese
# You can set the parameter `lang` as `ch`, `en`, `french`, `german`, `korean`, `japan`
# to switch the language model in order
ocr = PaddleOCR(use_angle_cls=True, lang='en') # need to run only once to download and load model into memory
img_path = 'PaddleOCR/doc/imgs_en/img_12.jpg'
result = ocr.ocr(img_path, cls=True)
for idx in range(len(result)):
    res = result[idx]
    for line in res:
        print(line)

# draw result
from PIL import Image
result = result[0]
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/fonts/simfang.ttf')
im_show = Image.fromarray(im_show)
im_show.save('result.jpg')
