写一个识别扑克牌花色和点数的小程序（三）

上一篇文章已经实现了如何识别花色和点数，这篇文章主要是用QT给程序加一个可视化界面。

由于我之前完全没有接触过QT，所以编写出来的界面很丑，QT在VS里自带一个界面设计师，类似于下图，编写个界面还是很方便的，对相关的控制直接写响应函数就可以了。

添加菜单和标签栏

实现一个从本地文件选取一张要识别图片的效果

对扑克牌图片进行识别，调用到前两章写到的函数

对识别结果进行显示

最后的效果如下

多张有些误差，将红桃10识别成了红桃9，梅花7识别成了黑桃7，其余正确，因为模板数量较小的问题，所以这个误差我还是可以接受的。

到这就完成了整个小程序的开发。现将程序的源码链接放在下面
