Pytesseract Image_to_string返回Windows错误:Python中的访问拒绝错误

I tried to read the text from the image using Pytesseract.I am getting Access denied message when I run the below script.

我试图使用Pytesseract从图像中读取文本。当我运行下面的脚本时，我将获得访问拒绝消息。

     from PIL import Image
     import pytesseract
     import cv2
     import os

     filename=r'C:\Users\ychandra\Documents\teaching-text-structure-3-728.jpg'
     pytesseract.pytesseract.tesseract_cmd = r'C:\Python27\Lib\site-packages\pytesseract'
     image=cv2.imread(filename)
     gray=cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)

     gray=cv2.threshold(gray,0,255,cv2.THRESH_BINARY|cv2.THRESH_OTSU)[1]
     gray=cv2.medianBlur(gray,3)

     filename='{}.png'.format(os.getpid())
     cv2.imwrite(filename,gray)

     text=pytesseract.image_to_string(Image.open(filename))
     print text

     cv2.imshow("image",image)
     cv2.imshow("res",gray)
     cv2.waitKey(0)

when I run the script I am getting below Error

当我运行这个脚本时，我得到了下面的错误

    Traceback (most recent call last):
    File "F:\opencv\New_folder_3\text_from_image.py", line 17, in <module>
text=pytesseract.image_to_string(Image.open(filename))

Your code works except the setting of pytesseract.pytesseract.tesseract_cmd. The tesseract_cmd should set to the tesseract executable file installed in your machine.

除了设置pytesserac .pytesserac .tesserac .tesseract_cmd之外，您的代码可以正常工作。tesseract_cmd应该设置为安装在您的计算机中的tesseract可执行文件。

Here is a sample usage of it.

这是它的一个示例用法。

pytesseract.pytesseract.tesseract_cmd = "C:/Program Files/Tesseract 4.0.0/tesseract.exe"

The tesseract_cmd is required if no properly search PATH setup in your Windows PC.

如果Windows PC中没有正确的搜索路径设置，则需要使用tesseract_cmd。

Hope this help.

希望这个有帮助。

UPDATE:

更新:

You need to have tesseract binary installed into your PC before using pytesseract which uses subprocess module to run tesseract in Windows shell from Python.

在使用pytesseract(使用子进程模块在Python的Windows shell中运行tesseract)之前，您需要将tesseract二进制文件安装到您的PC中。

Click this Tesseract 4.00 alpha to download a 64-bit Windows version and install it. Then setup the PATH and TESSDATA_PREFIX pointing to your tesseract.exe and ~\tessdata directory respectively.

单击这个Tesseract 4.00 alpha下载一个64位Windows版本并安装它。然后设置指向tesseract的路径和TESSDATA_PREFIX。exe和~\tessdata目录。

If you need any other language trained data file, you can get it [here].

如果您需要任何其他经过语言训练的数据文件，您可以在[这里]获得它。

In case the ~\tessdata directory is not found in your Windows, you can create it manually and copy at least one traineddata file to there, such as eng.traineddata for English.

如果在Windows中找不到~\tessdata目录，您可以手动创建它，并将至少一个traineddata文件复制到那里，例如eng。traineddata为英语。

If tesseract is working, it will return the version information when you type tesseract -v in command prompt as below.

如果tesseract正在工作，当您在命令提示符中键入tesseract -v时，它将返回版本信息，如下所示。
