python ddddocr 进行文字+数字验证码识别

一、python版本

将自动安装符合自己电脑环境的最新 ddddocr。Python 环境需要小于等于 3.9。

?

1	pip install ddddocr

　　

二、字母数字验证码

代码如下：

原始图片

 

 

?

1 2 3 4 5 6 7 8

import ddddocr   ocr = ddddocr.DdddOcr() with open('111.png','rb') as f:     img_bytes = f.read()   res = ocr.classification(img_bytes) print(res)

　　执行结果

 三、完整登录一个带验证码系统的代码

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34
