1.如果是初次配置OpenCV环境，需要在环境变量中增加以下路径(右击计算机，属性，环境变量)
在系统变量的PATH中添加
;D:\Opencv\opencv\build\x86\vc10\bin（根据安装位置而定）注意是添加，原有项目千万不要删掉，每项之间以英文状态下的分号隔开。
(未添加系统环境变量，会出现丢失dll文件的错误；添加完系统环境变量后，需要重启电脑)
//告诉编译器，头文件在哪里
项目--属性--VC++目录：
包含目录：D:\Opencv\opencv\build\include;
D:\Opencv\opencv\build\include\opencv;
D:\Opencv\opencv\build\include\opencv2;
库目录：D:\Opencv\opencv\build\x86\vc10\lib;
附加依赖项中复制添加下面的库文件
debug：
