Pytesser设置字符白名单 [英] Pytesser set character whitelist

问题描述

有人知道如何为Pytesseract设置角色白名单吗?我希望它仅输出A-z和0-9.这可能吗?我有以下内容:

Does anyone know how to set the character whitelist for Pytesseract? I want it to only output A-z and 0-9. Is this possible? I have the following:

img = Image.open('test.jpg')
result = pytesseract.image_to_string(img, config='-psm 6')

我将其他字符(例如/)设为1，所以我想限制可能出现的字符的选项.

I'm getting other characters like / for a 1 so I would like to limit the options of possible characters.

推荐答案

您可以在下面的行中完成此操作.或者，您可以为tesseract设置配置文件以执行相同的操作> tesseract正在寻找的限制字符

You can accomplish that with the below line. Or you can setup the config file for tesseract to do the same thing Limit characters tesseract is looking for

pytesseract.image_to_string(question_img, config="-c tessedit_char_whitelist=0123456789abcdefghijklmnopqrstuvwxyz -psm 6")

我确信还有其他方法可以使它起作用，但这对我来说是有效的.

I am sure there are other ways to get it work, but this is what worked for me.
