qt+opencv基本

下载的是 opencv2.4.9,系统是Windows7,自己同时下载了qt 5.7.1以及vs2013.

因此选择qt具体版本时选择了for 64bit的vs2013.

1.首先要配置好opencv的环境,主要是将opencv用到的dll的路径告诉电脑。应该将此路径编写在Path中.

2.安装好vs2013 ，安装好qt。

3.新建一个qt工程之后，类似于配置vs2013和opencv。在qt中配置都写在pro文件中

我自己电脑上会在原来的pro文件中添加如下内容：

适合debug,如果是release,把上面每一个lib的前缀的d去掉即可

然后执行qmake，环境就搭建好了
