其他 - Tesseract OCR在Python中的UnicodeDecodeError

The problem is that python is trying to use the console's encoding (CP1252) instead of what it's meant to use (UTF-8). PyTesseract has found a unicode character and is now trying to translate it into CP1252, which it can't do. On another platform you won't encounter this error because it will get to use UTF-8.

You can try using a different function (possibly one that returns bytes instead of str so you won't have to worry about encoding). You could change the default encoding of python as mentioned in one of the comments, although that will cause problems when you go to try and print the string on the windows console. Or, and this is my recommended solution, you could download Cygwin and run python on that to get a clean UTF-8 output.

如果您想要一种快速而又肮脏的解决方案，该解决方案不会破坏任何东西（尚未），请考虑以下方法：

import builtins

original_open = open
def bin_open(filename, mode='rb'):       # note, the default mode now opens in binary
    return original_open(filename, mode)

from PIL import Image
import pytesseract

img = Image.open('binarized_image.png')

try:
    builtins.open = bin_open
    bts = pytesseract.image_to_string(img)
finally:
    builtins.open = original_open

print(str(bts, 'cp1252', 'ignore'))
