opencv2.4.13怎么配置环境变量
step1：安装，选择你所想安装到的位置
step2：配置环境变量
1、给系统变量配置path:添加：D:\opencv2_4_13\opencv\build\x86\vc12\bin
2、给用户变量添加opencv变量，值D:\opencv2_4_13\opencv\build
添加PATH变量（有就不需要添加，但是值需要添加）值D:\opencv2_4_13\opencv\build\x86\vc12\bin
说明：不管你系统是32位还是64位，路径目录均选择X86，因为编译都是使用32位编译；如果选用X64，则程序运行时候会出错。
属性管理器：
注意：debug和release都要配置
1、debug：
1）VC++目录->包含目录
添加
D:\opencv2_4_13\opencv\build\include
D:\opencv2_4_13\opencv\build\include\opencv
D:\opencv2_4_13\opencv\build\include\opencv2
2）VC++目录->库目录
添加：
D:\opencv2_4_13\opencv\build\x86\vc12\lib
3）链接器->输入->附加依赖项
添加：
opencv_ml2413d.lib
opencv_calib3d2413d.lib
opencv_contrib2413d.lib
opencv_core2413d.lib
opencv_features2d2413d.lib
opencv_flann2413d.lib
opencv_gpu2413d.lib
opencv_highgui2413d.lib
opencv_imgproc2413d.lib
opencv_legacy2413d.lib
opencv_objdetect2413d.lib
opencv_ts2413d.lib
opencv_video2413d.lib
opencv_nonfree2413d.lib
opencv_ocl2413d.lib
opencv_photo2413d.lib
opencv_stitching2413d.lib
opencv_superres2413d.lib
opencv_videostab2413d.lib
2、Release
1）、2）与debug版本一样
3）添加：
opencv_objdetect2413.lib
opencv_ts2413.lib
opencv_video2413.lib
opencv_nonfree2413.lib
opencv_ocl2413.lib
opencv_photo2413.lib
opencv_stitching2413.lib
opencv_superres2413.lib
opencv_videostab2413.lib
opencv_calib3d2413.lib
opencv_contrib2413.lib
opencv_core2413.lib
opencv_features2d2413.lib
opencv_flann2413.lib
opencv_gpu2413.lib
opencv_highgui2413.lib
opencv_imgproc2413.lib
opencv_legacy2413.lib
opencv_ml2413.lib
测试
添加新建项test.cpp
输入代码：
#include <cv.h>
#include <highgui.h>
using namespace std;
int main()
{
IplImage * test;
test = cvLoadImage("D:\\Sample_8.bmp");//图片路径
cvNamedWindow("test_demo", 1);
cvShowImage("test_demo", test);
cvWaitKey(0);
cvDestroyWindow("test_demo");
cvReleaseImage(&test);
return 0;
}
