海康摄像头Sdk的使用 java Demo（idea 车牌识别，报警监听）
|
最近用到海康摄像头，起初遇到许多问题，发现网上没有比较直观的java demo，现在将其总结下，希望可以帮助大家 初步使用sdk 首先去官方下sdk：http://www.hikvision.com/Cn/download_more_401.html 导入idea里（这里直接导入了sdk里的，主要是给大家看 文件sdk这些东西应该放哪些位置） 导入之后，我们需要修改一下HCNetSDK.java 很多人都是在这一步出问题的，网上各种方法都有，本人也尝试很多，最后选择这种简单粗暴的方式` public interface HCNetSDK extends StdCallLibrary { HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary("E:\\haikang\\CH-HCNetSDKV6.1.4.6_build20191220_Win64\\Demo\\4- Java\\2-alarmDemo\\alarmJavaDemo\\HCNetSDK.dll", HCNetSDK.class); /***宏定义***/ //常量直接改绝对路径，看清楚，是HCNetSDK.dll的绝对路径，直接在你项目里找到HCNetSDK.dll，右键→Copy Path ，过来粘贴 //播放库函数声明,PlayCtrl.dll interface PlayCtrl extends StdCallLibrary { PlayCtrl INSTANCE = (PlayCtrl) Native.loadLibrary("E:\\haikang\\CH-HCNetSDKV6.1.4.6_build20191220_Win64\\Demo\\4- Java\\2-alarmDemo\\alarmJavaDemo\\lib\\PlayCtrl.dll", PlayCtrl.class);这个也一样PlayCtrl.dll的路径，用到播放的时候也要这个 4.接下来就是重点了，大体步骤，初始化，注册，登录，不妨，设置回调函数，撤防等，不多说，上码子： public class HikVisionService { private JTable jTableAlarm; static HCNetSDK hCNetSDK = HCNetSDK.INSTANCE; //alarmjavademo.HCNetSDK.NET_DVR_DEVICEINFO_V30 m_strDeviceInfo;//设备信息 NET_DVR_DEVICEINFO_V40 m_registerInfo; NET_DVR_USER_LOGIN_INFO m_loginInfo; //static alarmjavademo.HCNetSDK.NET_DVR_USER_LOGIN_INFO m_strLoginInfo = new alarmjavademo.HCNetSDK.NET_DVR_USER_LOGIN_INFO();//设备登录信息 //static alarmjavademo.HCNetSDK.NET_DVR_DEVICEINFO_V40 m_strDeviceInfo = new alarmjavademo.HCNetSDK.NET_DVR_DEVICEINFO_V40();//设备信息 static String m_sDeviceIP = "192.168.x.xxx";//已登录设备的IP地址 static String m_sUsername = "admin";//设备用户名 static String m_sPassword = "xxxxxx";//设备密码,默认的好像是12345 static short m_sPort = 8000;//端口号，这是默认的 public NativeLong lUserID;//用户句柄 public NativeLong lAlarmHandle;//报警布防句柄 public int lListenHandle;//报警监听句柄 public NativeLong RemoteConfig;

} } } public void initMemberFlowUpload(int remainMinuteTime) throws InterruptedException { // 初始化 Boolean flag = hCNetSDK.NET_DVR_Init(); if (flag){ System.out.println("初始化成功"); }else{ System.out.println("初始化失败");
