海康SDK+OpenCV+VS2017获取海康相机数据

参考链接：https://blog.csdn.net/o_ha_yo_yepeng/article/details/79825648

1.在海康官网下载sadp和ivms-4200测试并配置相机ip ，用户名和密码等

2.在海康官网下载相应版本sdk

3.新建一个c++工程

4.工程目录下建两个文件夹存放HCSDK的include和lib文件夹，OPENCV

 

将 \OPENCV\opencv\build\x64\vc15\lib  复制到目标文件夹

 将 OPENCV\opencv\build\include  复制到目标文件夹

 

  将OPENCV\opencv\build\x64\vc15\bin  复制到目标文件夹

 

OpenCV+VS2017配置：

5.打开解决方案的属性管理器，视图->其他窗口->属性管理器。

6.根据Debug或Release版本配置属性表或新建属性表

7.C/C++常规选项附加包含目录添加：D:\Tools\Platform_Test\HK_SDK\include

8.链接器输入选项添加：

D:\Tools\Platform_Test\HK_SDK\lib\HCNetSDKCom\HCAlarm.lib
D:\Tools\Platform_Test\HK_SDK\lib\HCNetSDKCom\HCPreview.lib
D:\Tools\Platform_Test\HK_SDK\lib\HCNetSDKCom\HCGeneralCfgMgr.lib
D:\Tools\Platform_Test\HK_SDK\lib\GdiPlus.lib
D:\Tools\Platform_Test\HK_SDK\lib\HCCore.lib
D:\Tools\Platform_Test\HK_SDK\lib\PlayCtrl.lib
D:\Tools\Platform_Test\HK_SDK\lib\HCNetSDK.lib
opencv_world455d.lib

 9.V/C++目录 库目录添加  D:\Tools\OPENCV\opencv\build\x64\vc15\lib

　　　　　　包含目录添加  D:\Tools\OPENCV\opencv\build\include      D:\Tools\OPENCV\opencv\build\include\opencv2

 

 10.编写代码

11.代码运行前将   海康sdkD:\Tools\CH-HCNetSDKV6.1.6.45_build20210302_win64\库文件中所有文件  复制到  D:\Tools\test\HC_OpenCV_Test\x64\Debug 或 D:\Tools\test\HC_OpenCV_Test\x64\Release

BUG：

提示bug：E1696无法打开源文件 "PlayM4.h"，解决办法：

到\CH-HCNetSDK(Windows64)V5.3.1.22_build20170909\Demo示例\2- MFC分功能示例\2- 实时流回调解码获取YUV\文件夹下找到PlayM4.h文件，添加到D:\Tools\Platform_Test\HK_SDK\include 文件夹下
