圖像到文本Pytesseract錯誤

Question

import pytesseract
from PIL import Image, ImageEnhance, ImageFilter
pytesseract.pytesseract.tesseract_cmd="C:\Program Files (x86)\Tesseract- 
OCR\tesseract.exe"
im = Image.open("d:\ss.png") # the second one 
im = im.filter(ImageFilter.MedianFilter())
enhancer = ImageEnhance.Contrast(im)
im = enhancer.enhance(2)
im = im.convert('1')
im.save('temp2.jpg')
text = pytesseract.image_to_string(Image.open('temp2.jpg'))
print(text)

上面是將圖像轉換為文本的代碼，但顯示以下錯誤：

Traceback (most recent call last):
  File "D:\txt14.py", line 10, in <module>
    text = pytesseract.image_to_string(Image.open('temp2.jpg'))
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python36\lib\site-packages\pytesseract\pytesseract.py", line 193, in image_to_string
    return run_and_get_output(image, 'txt', lang, config, nice)

您能幫我弄清楚為什么會發生此錯誤嗎？

Answer 1

pytesseract.pytesseract.tesseract_cmd="C:\Program Files (x86)\Tesseract-OCR\tesseract.exe"

路徑中的\\t不是反斜杠，而它是制表符。

對於源代碼中的Windows路徑名，如果要使用反斜杠而不是正斜杠，請始終使用原始字符串文字。 像這樣：

pytesseract.pytesseract.tesseract_cmd=r"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe"

在原始字符串文字中， \\t是反斜杠，而不是制表符。

您應該對'd:\\ss.png' -在那里您會很幸運，因為\\s碰巧不是任何東西的轉義序列（至少不是從Python 3.6起），但是比遺憾好得多。
