opencv讀取海康威視攝像頭
阿新 • • 發佈:2019-02-04
海康威視的網路攝像頭使用:
開發工具:vs2013 C++ 海康SDK
下載海康威視SDK:網址:http://www.hikvision.com/cn/download_61.html
• 1:對照自己的開發平臺可以下載裝置網路SDK_Win32裝置網路SDK_Win64,解壓到本地檔案下:
• 2:VS配置
• Opencv配置。參考址 http://blog.csdn.net/poem_qianmo/article/details/19809337
• 建議自己建立一個專案屬性表這樣方便使用
• SDK庫檔案和標頭檔案配置
• 解壓SDK可以得到標頭檔案和庫檔案
• 在VC++目錄中新增opencv的標頭檔案包含路徑和SDK中的標頭檔案(修改“標頭檔案”為“include”)
新增庫檔案:既要新增庫檔案lib也要把lib下的HCNetSDKCom檔案包含進去
再連結器——輸入——新增依賴項,把opencv的lib和SDK中的lib新增進去(包含HCNetSDKCom的lib)
opencv_ml249d.lib
opencv_calib3d249d.lib
opencv_contrib249d.lib
opencv_core249d.lib
opencv_features2d249d.lib
opencv_flann249d.lib
opencv_gpu249d.lib
opencv_highgui249d.lib
opencv_imgproc249d.lib
opencv_legacy249d.lib
opencv_objdetect249d.lib
opencv_ts249d.lib
opencv_video249d.lib
opencv_nonfree249d.lib
opencv_ocl249d.lib
opencv_photo249d.lib
opencv_stitching249d.lib
opencv_superres249d.lib
opencv_videostab249d.lib
GdiPlus.lib
HCCore.lib
HCNetSDK.LIB
PlayCtrl.lib
HCAlarm.lib
HCGeneralCfgMgr.lib
HCPreview.lib
配置完成後就可以新增CPP檔案。
