字符型验证码,如下:

<code>         __   __    ______   _    _    __   __   __   _      ___    
 \ \\/ //  /_   _// | || | ||  \ \\/ // | || | ||   / _ \\  
  \   //    -| ||-  | || | ||   \ ` //  | '--' ||  / //\ \\ 
  / . \\    _| ||_  | \\_/ ||    | ||   | .--. || |  ___  ||
 /_//\_\\  /_____//  \____//     |_||   |_|| |_|| |_||  |_||
 `-`  --`  `-----`    `---`      `-`'   `-`  `-`  `-`   `-` 
</code>

它跟普通的图片验证码相比如何,被机器识别的几率相比于图片验证码如何?

这个更容易识别啊 每个字母的特征值更容易提取了

高太多,甚至都不用专门算法,就渲染成图片识别,没有变形扭曲重叠干扰,最烂的OCR算法也基本不会出错……
