python3.5+tesseract+adb实现西瓜视频或头脑王者辅助答题
最近的答题赢钱很火爆，我也参与了几次，有些题目确实很难答，但是10秒钟的时间根本不够百度的，所以写了个辅助挂，这样可以出现题目时自动百度，这个时间也就花掉2秒钟，剩下的7、8秒钟可以进行分析和作答，提升了赢钱概率。
源码可以见我的github：点击链接
原理分析下：使用adb命令，抓取手机视频播放的界面，然后通过python的截取和ocr，获得到题目和答案, 然后百度得到结果。这个环境怎么搭建，有需要的童鞋可以联系我，因为使用本地的ocr所以解析不花钱，也没有使用的限制。
github上的代码中
ocr_bw.py，这个是自动根据题目去百度，然后打开浏览器，展示检索结果

由于很多题目是下列哪个不是，所以我更喜欢用第一个方式，基本上识别时间在0.5-0.6秒之间。
最后里面的ocr_zh.py是可以用来抓取头脑王者的辅助。
