win10 64 + VS2010 + Opencv 2.4.9 + HIKVISION(海康)

海康相机型号：DS-2CD2512F-IS

参考连接http://blog.csdn.net/wanghuiqi2008/article/details/31404571

先上效果图

其中，在连接时遇到了X64与X86兼容问题：

海康SDK在X64（配置时用的时X64），程序运行时采用的X64，但opencv2.4.9配置时又采用的时X86，所以在使用X64的时候，会出现opencv找不到lib文件，所有在程序中添加了以下代码：

 #pragma comment( lib, "opencv_highgui249d.lib")

 #pragma comment( lib, "opencv_core249d.lib")

 #pragma comment( lib, "opencv_imgproc249d.lib")

主要程序如下：

 #include <cstdio>

 #include <iostream>

 #include <ctime>

 #include <Windows.h>

 #include "HCNetSDK.h"

 #include "highgui.h"

 #include "cv.h"

  #pragma comment( lib, "opencv_highgui249d.lib")

  #pragma comment( lib, "opencv_core249d.lib")

  #pragma comment( lib, "opencv_imgproc249d.lib")
