在添加摄像头线程时，改了半天错误之后，可运行了，但是给我提示 segment fault，哈哈哈，心态崩了。当时我就关了树莓派打起了LOL，这一打就是一下午。晚上接着处理段错误，无果，第二天，无果。第二天晚上在图书馆发呆想到了找段错误的一种方法：printf调试法，晚上回到宿舍用了printf调试法十分钟就找到了错误，然后改正，运行成功，人脸识别成功。

有的书上是这么说的，如果函数定义放在main函数前面，可以不用写声明。如果函数放在main函数后面，就规定要写函数声明。这么说没毛病。
不过有的地方又说：如果在函数定义在这个函数调用之前，就不需要写声明。否则就要写声明。
大家稍微注意下就行。为了防止报错的话，只要是函数都给声明就行了。
