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)
以上是将图像转换为文本的代码,但它显示以下错误:
Traceback (most recent call last):

你能帮我弄清楚这个错误发生的原因吗?
答案 0 :(得分:1)
pytesseract.pytesseract.tesseract_cmd="C:\Program Files (x86)\Tesseract-OCR\tesseract.exe"
路径中的\t
不是反斜杠而是t,它是制表符。
对于源代码中的Windows路径名,如果要使用反斜杠而不是正斜杠,请始终使用原始字符串文字。像这样:
pytesseract.pytesseract.tesseract_cmd=r"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe"
在原始字符串文字中,\t
是反斜杠和t,而不是制表符。
你应该对'd:\ss.png'
做同样的事情 - 你很幸运,因为\s
碰巧不是任何事情的转义序列(至少不是Python 3.6),但比遗憾。
