环境：

win7

vs2010

opencv>opencv2.4.9

oepncv下载：http://opencv>opencv.org/downloads.html

1.安装opencv>opencv

下载opencv>opencv后在电脑中安装，如安装路径为：D:\opencv>opencv

2.配置opencv>opencv环境变量

• 右键点击：计算机属性；配置环境变量D:\opencv>opencv\build\x86\vc10\bin

• (注意配置完环境变量，记得重启或注销一下，最好重启，这点也是大家配置好，但是Opencv有些库不能用的原因)

3.工程中添加目录、库目录、附加依赖项

• 包含目录：

D:\opencv>opencv\build\includeD:\opencv>opencv\build\include\opencv>opencvD:\opencv>opencv\build\include\opencv>opencv2

• 库目录：

D:\opencv>opencv\build\x86\vc10\lib

• 附加依赖项：**

注意：

建议用到哪几个lib 、dll就添加哪几个lib、dll，当然都加进去也是没有问题的，但是当你打包发布或 做ocx控件时，有时候就麻烦了,并且都添加进去整个代码体积也会很大。注意debug下的 lib、dll和release下的lib、dll是不一样的。

如下是整个opencv>opencv2.4.9的debug下的lib。

opencv>opencv_calib3d249d.lib
opencv>opencv_contrib249d.lib
opencv>opencv_core249d.lib
opencv>opencv_features2d249d.lib
opencv>opencv_flann249d.lib
opencv>opencv_gpu249d.lib
opencv>opencv_highgui249d.lib
opencv>opencv_imgproc249d.lib
opencv>opencv_legacy249d.lib
opencv>opencv_ml249d.lib
opencv>opencv_nonfree249d.lib
opencv>opencv_objdetect249d.lib
opencv>opencv_photo249d.lib
opencv>opencv_stitching249d.lib
opencv>opencv_ts249d.lib
opencv>opencv_video249d.lib
opencv>opencv_videostab249d.lib

4.简单测试

/IplImage格式
#include "cv.h"
#include "highgui.h"
int main()
{
	IplImage* src = cvLoadImage("G:\\test2.jpg");//此处的路径，一定是绝对路径，相对路径会报错的
	cvNamedWindow("showImage");
	cvShowImage("showImage",src);
	cvWaitKey(0);
	cvReleaseImage(&src);
	cvDestroyWindow("showImage");
	return 0;
}

/Mat格式
#include "cv.h"
#include "highgui.h"
using namespace cv;
int main()
{
	Mat src=imread("G:\\test2.jpg");
	imshow("showImage",src);
	waitKey(0);
	return 0;
}
