python - 在 Python 上使用 Tesseract-OCR 的问题

Question

我是编程新手，我正在尝试使用 Tesseract OCR 来读取图像的文本，但我无法使其工作!我在我的环境中安装了tesseract_OCR、pytesseract和pillow。有人有提示吗？

输入:

from PIL import Image 

import pytesseract

print( pytesseract.image_to_string( Image.open('phrase.jpg') ) ) 

输出:

 C:\Anaconda2\envs\ambiente36\python.exe 

 C:/Users/Simone/Desktop/curso_programacao/Ler_imagens/ler_imagens

Traceback (most recent call last):

在您的环境中配置 tessaract 时应遵循的步骤这是您应该遵循的步骤

首先安装python和pip here是步骤然后安装pillow，pytesseract为here

from PIL import Image
from pytesser.pytesser import *

image_file = "FULL/PATH/TO/YOUR/IMAGE/image.png"
im = Image.open(image_file)
text = image_to_string(im)
text = image_file_to_string(image_file)
text = image_file_to_string(image_file, graceful_errors=True)
print "=====output=======\n"
print text
