这是我的问题,我想用pytesser来获取图片的内容.我的操作系统是Mac OS 10.11,我已经安装了PIL,pytesser,tesseract-ocr引擎和其他支持库,如libpng等.但是当我运行我的代码时,如下所示,会发生错误.
from pytesser import *
import os
image = Image.open('/Users/Grant/Desktop/1.png')
text = image_to_string(image)
print text

此外,tesseract-ocr引擎在我的Mac上运行良好,我可以在终端运行它并获得结果.以下是测试图片结果. tesseract结果
有人可以帮我解决这个问题吗?
打开文件pytesseract.py.
我在 /Users/yourUser/.virtualenvs/cv/lib/python2.7/site-packages/pytesseract/pytesseract.py
更改tesseract_cmd = 'tesseract'到tesseract_cmd = '/usr/local/bin/tesseract'

幸运的是,我解决了这个问题.
首先,我运行命令
pip install pytesseract

安装包.
但是我收到了"没有这样的文件或目录使用pytesser"的错误消息.
然后我读了这个链接:image_to_string在Mac中不起作用 所以,只需运行以下脚本:
brew link libtiff
brew link libpng
brew link jpeg
brew install tesseract

我有同样的问题,但我设法将图像转换为字符串。使用apt-get应该可以解决问题:
sudo apt-get install tesseract-ocr

如果您不能在 python 脚本中使用它,请执行以下操作:
from os import system
system("tesseract -l eng /image.png text.txt")
