【问题描述】:
以下代码在我朋友的 Windows 笔记本电脑上完美运行,但在我的笔记本电脑上,它吐出完全垃圾。我认为这可能与图书馆有关,但我不能肯定地说?你们能告诉我它是否适合您,或者您以前是否曾经发生过这种情况?
import pytesseract
from PIL import Image, ImageEnhance, ImageFilter
from textblob import TextBlob
originalImage = Image.open("pictures\hp.png")
workingImage = originalImage.copy()
workingImage = originalImage.filter(ImageFilter.MedianFilter())
enhanceSharpness = ImageEnhance.Sharpness(workingImage)
enhanceColor = ImageEnhance.Color(workingImage)
workingImage = enhanceSharpness.enhance(2)
workingImage = enhanceColor.enhance(0)
workingImage = workingImage.convert('1')
text = pytesseract.image_to_string(workingImage)
correctedText = TextBlob(text).correct()
print(correctedText)
我没有像在我朋友的电脑上那样打印照片中的文字,而是打印以下内容:

【问题讨论】:
-
我得到与你在 Linux 上使用 Python 3.7.0、pytesseract 0.2.6、libtesseract3、tesseract-ocr 3.05.01-lp150.1.1 相同的(乱码)输出。
-
相反,我使用 Python 3.6.7、tesseract-ocr 4.00(在 Ubuntu 18.04 上)得到(大约)正确的输出。
-
我有 tesseract-ocr 版本 3.05.02 也许我需要像你一样的 4.0 Josh。如果它解决了问题,我会告诉你
-
我也得到了大致正确的输出。我发现有时可以通过将图像的大小增加大约 5 倍,然后将其放入 pytesseract 来解决此问题。
