OpenCV3对比2版本添加了一些功能，如果需要配置OpenCV3.1库
去opencv官网下载相对应的版本 我这里下载的是opencv3.1
然后去VS里面添加新属性表（以后就不用每次配置。直接点击添加现有的属性表 找到之前的配置属性表即可）
选择的模块应与最上面的选项相同，一般选择Debug模式x64位（我这里是为了生成dll文件使用python对C++程序进行调用才设置的Release模式）
包含目录
D:\opencv3.1.0\tools\opencv_contrib\install\include
库目录
D:\opencv3.1.0\tools\opencv_contrib\install\lib
D:\opencv3.1.0\tools\opencv_contrib\install\staticlib

以后每次再创建新项目使用相同的库就可以直接点击添加现有的属性表了
OpenCV2配置大致相同 但属性表配置不太一致
