在非结构化数据中搜索文本

Question

我已经编写了一部分代码来使用 python 从图像中读取文本。图片是发票。

import pytesseract as tess
tess.pytesseract.tesseract_cmd = r'C:\Users\Me\AppData\Local\Tesseract-OCR\tesseract.exe'
from PIL import Image

img = Image.open('C:/Users/Me/Desktop/PM/Invoice Formats/TestInv.png')


text = tess.image_to_string(img)
print(text)

代码的结果是发票文本。我有多张不同格式的发票。 谁能帮我从这些非结构化文本中提取发票编号、发票日期和发票金额？

对于少数发票，得到的文本有点像这样。对于其他人来说，它是不同的

Answer 1

让我向您展示一个提取日期的示例，然后您可以推断以提取其他日期：

date = text.split('Date: ')[1].split(',')[0]
print(date)

'01/02/2019'
