当Python遇到PIL|pytesser图像处理出错

来源：互联网发布：移动互联网大数据编辑：程序博客网时间：2024/06/05 02:44

import pytesserFrom PIL import Imageim = Image.open('1.png')im.show()#查看图片print pytesser.image_to_string(im)#识别图像的字符串

这样会报错如下：C:\Python27\python.exe C:/Users/ED/PycharmProjects/untitled/1t.pyTraceback (most recent call last):  File "C:/Users/ED/PycharmProjects/untitled/1t.py", line 14, in <module>    print pytesser.image_to_string(im)  File "C:\Python27\lib\site-packages\pytesser\pytesser.py", line 31, in image_to_string    call_tesseract(scratch_image_name, scratch_text_name_root)  File "C:\Python27\lib\site-packages\pytesser\pytesser.py", line 21, in call_tesseract    proc = subprocess.Popen(args)  File "C:\Python27\lib\subprocess.py", line 709, in __init__    errread, errwrite)  File "C:\Python27\lib\subprocess.py", line 957, in _execute_child    startupinfo)WindowsError: [Error 2]

解决方法：import  osos.chdir('c:/Python27/Lib/site-packages/pytesser')#修改工作路径即可简单的数字和英文的图像识别就完成了
