在本文中我的电脑是使用的Ubuntu16.04 64位使用工具是QT5.7.1opencv2.4.9.一、根据电脑的型号下载海康威视的SDK包网址http://www.hikvision.com/cn/download_61.html。我的笔记本时linux64位的所以下载的 ————设备网络SDK_Linux64 二、 用下面的方法之一配置SDK如果HCNetSDKCom目录以及libhcnetsdk.so、libhpr.so、libHCCore文件和可执行文件在同一级目录下则使用同级目录下的库文件; 如果不在同一级目录下则需要将以上文件的目录加载到动态库搜索路径中设置的方式有以下几种: 1. 将网络SDK各动态库路径加入到LD_LIBRARY_PATH环境变量 1.在终端输入export LD_LIBRARY_PATH$LD_LIBRARY_PATH:/XXX:/XXX/HCNetSDKCom 只在当前终端起作用 2. 修改~/.bashrc或~/.bash_profile最后一行添加 export LD_LIBRARY_PATH$LD_LIBRARY_PATH:/XXX:/XXX/HCNetSDKCom保存之后使用source .bashrc执行该文件 当前用户生效 3. 修改/etc/profile添加内容如第2条同样保存之后使用source执行该文件 所有用户生效
2在/etc/ld.so.conf文件结尾添加网络sdk库的路径如/XXX和/XXX/HCNetSDKCom/保存之后然后执行ldconfig。
三. 在Ubuntu16.04 的qt中新建一个工程1. 在工程的 ×.pro文件中添加以下内容[plain] view plaincopyINCLUDEPATH /usr/local/include \ /usr/local/include/opencv \ /usr/local/include/opencv2 LIBS /usr/local/lib/libopencv_calib3d.so\ /usr/local/lib/libopencv_ml.so.2.4.9\ /usr/local/lib/libopencv_calib3d.so.2.4 \ /usr/local/lib/libopencv_nonfree.so\ /usr/local/lib/libopencv_calib3d.so.2.4.9 \ /usr/local/lib/libopencv_nonfree.so.2.4\ /usr/local/lib/libopencv_contrib.so \ /usr/local/lib/libopencv_nonfree.so.2.4.9\ /usr/local/lib/libopencv_contrib.so.2.4 \ /usr/local/lib/libopencv_objdetect.so\ /usr/local/lib/libopencv_contrib.so.2.4.9 \ /usr/local/lib/libopencv_objdetect.so.2.4\ /usr/local/lib/libopencv_core.so\ /usr/local/lib/libopencv_objdetect.so.2.4.9\ /usr/local/lib/libopencv_core.so.2.4 \ /usr/local/lib/libopencv_ocl.so\ /usr/local/lib/libopencv_core.so.2.4.9 \ /usr/local/lib/libopencv_ocl.so.2.4\ /usr/local/lib/libopencv_features2d.so \ /usr/local/lib/libopencv_ocl.so.2.4.9\ /usr/local/lib/libopencv_features2d.so.2.4 \ /usr/local/lib/libopencv_photo.so\ /usr/local/lib/libopencv_features2d.so.2.4.9 \ /usr/local/lib/libopencv_photo.so.2.4\ /usr/local/lib/libopencv_flann.so \ /usr/local/lib/libopencv_photo.so.2.4.9\ /usr/local/lib/libopencv_flann.so.2.4 \ /usr/local/lib/libopencv_stitching.so\ /usr/local/lib/libopencv_flann.so.2.4.9 \ /usr/local/lib/libopencv_stitching.so.2.4\ /usr/local/lib/libopencv_gpu.so \ /usr/local/lib/libopencv_stitching.so.2.4.9\ /usr/local/lib/libopencv_gpu.so.2.4 \ /usr/local/lib/libopencv_superres.so\ /usr/local/lib/libopencv_gpu.so.2.4.9 \ /usr/local/lib/libopencv_superres.so.2.4\ /usr/local/lib/libopencv_highgui.so \ /usr/local/lib/libopencv_superres.so.2.4.9\ /usr/local/lib/libopencv_highgui.so.2.4 \ /usr/local/lib/libopencv_highgui.so.2.4.9 \ /usr/local/lib/libopencv_video.so\ /usr/local/lib/libopencv_imgproc.so \ /usr/local/lib/libopencv_video.so.2.4\ /usr/local/lib/libopencv_imgproc.so.2.4 \ /usr/local/lib/libopencv_video.so.2.4.9\ /usr/local/lib/libopencv_imgproc.so.2.4.9\ /usr/local/lib/libopencv_videostab.so\ /usr/local/lib/libopencv_legacy.so \ /usr/local/lib/libopencv_videostab.so.2.4\ /usr/local/lib/libopencv_legacy.so.2.4 \ /usr/local/lib/libopencv_videostab.so.2.4.9\ /usr/local/lib/libopencv_legacy.so.2.4.9 \ /usr/local/lib/libopencv_ml.so INCLUDEPATH /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/incCn LIBS /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/lib/libhcnetsdk.so\ /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/lib/libHCCore.so\ /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/lib/libhpr.so\ /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/lib/libPlayCtrl.so\ /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/lib/libSuperRender.so\ /home/ding/opencv_projects/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/lib/libAudioRender.so 2. 在main.cpp函数中添加以下内容[cpp] view plaincopy#include opencv2/opencv.hpp #include QDir #include fstream #include unistd.h //#include auto_entercs.h #include HCNetSDK.h #include PlayM4.h #include LinuxPlayM4.h #define HPR_ERROR -1 #define HPR_OK 0 #define USECOLOR 0 static cv::Mat dst; HWND h NULL; LONG nPort-1; LONG lUserID; pthread_mutex_t mutex; std::listcv::Mat g_frameList; FILE *g_pFile NULL; void CALLBACK PsDataCallBack(LONG lRealHandle, DWORD dwDataType,BYTE *pPacketBuffer,DWORD nPacketSize, void* pUser) { if (dwDataType NET_DVR_SYSHEAD) { //写入头数据 g_pFile fopen(/home/lds/source/ps.dat, wb); if (g_pFile NULL) { printf(CreateFileHead fail\n); return; } //写入头数据 fwrite(pPacketBuffer, sizeof(unsigned char), nPacketSize, g_pFile); printf(write head len%d\n, nPacketSize); } else { if(g_pFile !
