之前没想过会有这么多朋友遇到问题，所以建了一个qq群536898072，专门供大家以后一起交流讨论图像和机器学习的工程实践问题。

环境

  • 硬件：
    PC：i7-4970 16GB内存 摄像头型号：DS-2CD3310D-I（2.8mm）
  • 软件：
    windows-x64、vs2012、opencv2.4.8、hkvision5114-x64版本库

配置

  • 保证使用SADP工具可以识别摄像头，然后配置IP与电脑在同一个网段。
    这里写图片描述
  • 再保证可以从浏览器中访问。账号密码默认的一般是admin、a123456789(老版本的摄像头密码是12345)。
    这里写图片描述
    登录成功后可能要求下载WebComponent控件，下载好了安装便是。如果仍然出现如下画面：
    这里写图片描述
    则换一种浏览器试。一般是默认浏览器没问题的。
    这里写图片描述
  • 配置使用sdk中自带的ClientDemo.exe工具可以访问
    这里写图片描述
    这里写图片描述
  • 配置sdk开发环境
    – opencv的配置
    这里不展开讲opencv的配置，仅说明需要配置opencv环境变量、设置好对应的vs开发环境的属性配置
    这里写图片描述
    这里写图片描述
    这里写图片描述
    – 海康威视sdk属性配置
    因为是64位环境，为了增强属性配置的内聚性，单独添加新项目属性表，设置海康威视sdk的属性
    这里写图片描述
    这里写图片描述
    这里写图片描述
    这里写图片描述
    依赖库写全，为：
    HCNetSDK.lib;PlayCtrl.lib;ws2_32.lib;winmm.lib;GdiPlus.lib;IPHlpApi.Lib;%(AdditionalDependencies)

其中最终得到的帧保存在g_frameList.push_back(frametemp);中。前后设置了对应的锁，用来对该帧序列的读写进行保护。这一部分内容是要自己完成的。即定义变量：

CRITICAL_SECTION g_cs_frameList;
std::list g_frameList;

主函数中的调用代码，先建立线程，调用上述读摄像头的函数的回调，并把读到的帧序列保存在g_frameList中，然后再读取该序列，保存到Mat里即可：

  • 受益匪浅，作者步骤详细，希望代码能多加点注释就更好了，想请问一下，经常看到有yuv的转换，请问现在摄像头拍出来都是什么格式的，怎么还要转换？
