在Ubuntu下使用opencv调用海康威视的网络摄像头

经过很多天的配置，终于能在工程中调用海康威视的网络摄像头了，为了后人能快速上手，我整理内容如下：

在本文中我的电脑是使用的Ubuntu16.04 64位，使用工具是QT5.7.1，opencv2.4.9.
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：

 INCLUDEPATH += /usr/local/include \
 /usr/local/include/opencv \
 /usr/local/include/opencv2
