pytesseract识别PDF文件中的文字（OCR） 第三方库：pdf2image,pytesseract,numpy 需要将tesseract安装路径添加到环境变量

初试

  1. import numpy as np
  2. import pytesseract
  3. from pdf2image import convert_from_path
  5. def pdf_ocr(fname, **kwargs):
  6.     images = convert_from_path(fname, **kwargs)
  7.     text = ''
  8.     for img in images:
  9.         img = np.array(img)
  10.         text += pytesseract.image_to_string(img)
  11.     return text
  13. fname = 'example.pdf'
  14. # text = pdf_ocr(fname, first_page=7, last_page=8)
  15. text = pdf_ocr(fname)
  16. print(text)

可能出现的错误

错误：pdf2image.exceptions.PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?
解决：**conda install -c conda-forge poppler**
