好的，当我使用 tesseract 运行您的代码时，您提供的图像完美地返回了文本（包括破折号和空格）。那时你显然可以使用txt = txt.replace("-", "").replace(" ", "") 来去掉破折号和空格。
Buuuuuut 我知道 OCR（即使我们都使用 tesseract）在不同平台上会有所不同，所以我提供了一个我的评论建议示例。
首先我们在破折号处分割图像，然后读取每个分割图像，然后连接：
# I changed your imports a bit
from PIL import Image
from pyocr import pyocr
from pyocr import builders
import cStringIO
import os
# set up all your OCR stuff
os.putenv("TESSDATA_PREFIX", "/usr/share/tesseract-ocr/")
tools = pyocr.get_available_tools()
tool = tools[0]
langs = tool.get_available_languages()
lang = "eng" #set language to english to simplify things
# definte a function to return the text of a given image
def doOCR( fName ):
txt = tool.image_to_string(Image.open(fName), lang=lang, builder=builders.TextBuilder())
return txt
# define the path of the image we are going to read
path = "test.png"
# get the image dimensions
im = Image.open(path)
width, height = im.size
# define the points we want to split the image at
# these are the points where the dashes are
split_points = [119, 158]
# define the file names for the image parts
split_names = ["split-1.png", "split-2.png", "split-3.png"]
# define a function to crop the image and remove the dashes
def doCrop(imagePath, cropPath, x, y, x2, y2):
im = Image.open(imagePath)
box = (x, y, x2, y2)
region = im.crop(box) # extract the box region
region.save(cropPath) # save it as a separate image
# in the image you provided each "-" is ~10 pixels long
lenpix = 10
# crop the image at the split points
doCrop(path, split_names[0], 0, 0, split_points[0], height) # get the first section
doCrop(path, split_names[1], split_points[0] + lenpix, 0, split_points[1], height) # get the middle section
doCrop(path, split_names[2], split_points[1] + lenpix, 0, width, height) # get the final section
# define a variable for our final value
finalValue = ""
# finally iterate through split files
# and add the OCR results from each split together
for f in split_names:
finalValue += doOCR(f) # concatenate the ocr value with the final
os.remove(f) # remove the split file now that we've used it
# display the final value
print finalValue
对我来说就像一个魅力：
希望这有帮助！
