海康SDK+OpenCV+VS2017獲取海康相機數據

 

參考鏈接：https://blog.csdn.net/o_ha_yo_yepeng/article/details/79825648

 

1.在海康官網下載sadp和ivms-4200測試並配置相機ip ，用戶名和密碼等

2.在海康官網下載相應版本sdk

3.新建一個c++工程

4.工程目錄下建兩個文件夾存放HCSDK的include和lib文件夾，OPENCV

 

 

 

將 \OPENCV\opencv\build\x64\vc15\lib  復制到目標文件夾

 

 將 OPENCV\opencv\build\include  復制到目標文件夾

 

 

  將OPENCV\opencv\build\x64\vc15\bin  復制到目標文件夾

 

 

 

OpenCV+VS2017配置：

參考：https://blog.csdn.net/qq_41175905/article/details/80560429?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-13.nonecase&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-13.nonecase

 

5.打開解決方案的屬性管理器，視圖->其他窗口->屬性管理器。

6.根據Debug或Release版本配置屬性表或新建屬性表

 

7.C/C++常規選項附加包含目錄添加：D:\Tools\Platform_Test\HK_SDK\include

8.鏈接器輸入選項添加：

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++目錄 庫目錄添加  D:\Tools\OPENCV\opencv\build\x64\vc15\lib

　　　　　　包含目錄添加  D:\Tools\OPENCV\opencv\build\include      D:\Tools\OPENCV\opencv\build\include\opencv2

11.代碼運行前將   海康sdkD:\Tools\CH-HCNetSDKV6.1.6.45_build20210302_win64\庫文件中所有文件  復制到  D:\Tools\test\HC_OpenCV_Test\x64\Debug 或 D:\Tools\test\HC_OpenCV_Test\x64\Release

 

 

BUG：

提示bug：E1696無法打開源文件 "PlayM4.h"，解決辦法：

到\CH-HCNetSDK(Windows64)V5.3.1.22_build20170909\Demo示例\2- MFC分功能示例\2- 實時流回調解碼獲取YUV\文件夾下找到PlayM4.h文件，添加到D:\Tools\Platform_Test\HK_SDK\include 文件夾下
