JAVA使用海康SDK

首先到海康威视官网下载SDK

海康威视SDK

1.导入项目时候需要注意，linux环境跟windows不同的
区别如下：

public interface HCNetSDK extends Library //linux
public interface HCNetSDK extends StdCallLibrary //windows

2.初始化SDK

	public static HCNetSDK hCNetSDK;{hCNetSDK = HCNetSDK.INSTANCE;boolean b = hCNetSDK.NET_DVR_Init();if (b) {log.info("海康SDk初始化成功");} else {log.info("海康SDk初始化失败");}}

3.查看SDK调用的流程以及参考Demo（黄色部分可以在摄像头直接设置）
使用流程
4.参考示例是C语言的，我们需要对应转换成JAVA代码，首先设置一个回调函数

public class MsgCallBack_V31 implements HCNetSDK.FMSGCallBack_V31 {@Overridepublic boolean invoke(int lCommand, HCNetSDK.NET_DVR_ALARMER pAlarmer, Pointer pAlarmInfo, int dwBufLen, Pointer pUser) {switch (lCommand) {case HCNetSDK.COMM_VCA_ALARM: // 智能检测通用报警{break;}case HCNetSDK.COMM_ISAPI_ALARM: {//图片分离模式//触发事件终端ipString terminalIp = new String(pAlarmer.sDeviceIP).trim();//写入接收结构体HCNetSDK.NET_DVR_ALARM_ISAPI_INFO strDvrAlarmIspi = new HCNetSDK.NET_DVR_ALARM_ISAPI_INFO();strDvrAlarmIspi.write();Pointer pVcaIspiInfo = strDvrAlarmIspi.getPointer();pVcaIspiInfo.write(0, pAlarmInfo.getByteArray(0, strDvrAlarmIspi.size()), 0, strDvrAlarmIspi.size());strDvrAlarmIspi.read();break;}default:System.out.println("其他报警，报警信息类型: " + lCommand);break;}return true;
}

5.开始对摄像头进行布防，废话不多说，直接上代码

@Service
public class TerminalSdkServiceImpl{public static HCNetSDK hCNetSDK = HCNetSDK.INSTANCE;public static HCNetSDK.FMSGCallBack_V31 fMSFCallBack_V31;//报警回调函数实现public void InitTerminal(String ip, String userName, String password, short port) {fMSFCallBack_V31 = new MsgCallBack_V31();// 初始化if(hCNetSDK == null) {hCNetSDK.NET_DVR_Init();}//建议使用图片分离模式，否则解析会内存溢出或者引发其他问题HCNetSDK.NET_DVR_LOCAL_GENERAL_CFG struGeneralCfg = new HCNetSDK.NET_DVR_LOCAL_GENERAL_CFG();struGeneralCfg.byAlarmJsonPictureSeparate = 1;// 分离模式0不分离，1分离struGeneralCfg.write();if (!hCNetSDK.NET_DVR_SetSDKLocalCfg(17, struGeneralCfg.getPointer())) {JOptionPane.showMessageDialog(null, "NET_DVR_SetSDKLocalCfg失败");}// 设置连接时间与重连时间hCNetSDK.NET_DVR_SetConnectTime(2000, 1);hCNetSDK.NET_DVR_SetReconnect(10000, true);// 登录参数，包括设备地址、登录用户、密码等HCNetSDK.NET_DVR_USER_LOGIN_INFO struLoginInfo = new HCNetSDK.NET_DVR_USER_LOGIN_INFO();// 设备IP地址struLoginInfo.sDeviceAddress = new byte[HCNetSDK.NET_DVR_DEV_ADDRESS_MAX_LEN];System.arraycopy(ip.getBytes(), 0, struLoginInfo.sDeviceAddress, 0, ip.length());//用户名struLoginInfo.sUserName = new byte[HCNetSDK.NET_DVR_LOGIN_USERNAME_MAX_LEN];System.arraycopy(userName.getBytes(), 0, struLoginInfo.sUserName, 0, userName.length());//设备登录密码struLoginInfo.sPassword = new byte[HCNetSDK.NET_DVR_LOGIN_PASSWD_MAX_LEN];System.arraycopy(password.getBytes(), 0, struLoginInfo.sPassword, 0, password.length());struLoginInfo.bUseAsynLogin = false; // 同步登录方式struLoginInfo.wPort = port; // 设备服务端口struLoginInfo.write();// 设备信息, 输出参数HCNetSDK.NET_DVR_DEVICEINFO_V40 struDeviceInfoV40 = new HCNetSDK.NET_DVR_DEVICEINFO_V40();lUserID = hCNetSDK.NET_DVR_Login_V40(struLoginInfo, struDeviceInfoV40);if (lUserID < 0) {System.out.println("Login failed, error code: " + hCNetSDK.NET_DVR_GetLastError());hCNetSDK.NET_DVR_Cleanup();return;}else{System.out.println("设备ip:" + ip + "登录成功！");}// 设置报警回调函数hCNetSDK.NET_DVR_SetDVRMessageCallBack_V31(fMSFCallBack_V31, null);int lHandle;HCNetSDK.NET_DVR_SETUPALARM_PARAM struAlarmParam = new HCNetSDK.NET_DVR_SETUPALARM_PARAM();struAlarmParam.dwSize = struAlarmParam.size();// 报警图片数据类型，bit1-报警类型为COMM_VCA_ALARM对应的json报警数据中图片数据长传类型，0- 二进制传输，1- URL传输struAlarmParam.byAlarmTypeURL = 1 << 1;// 其他报警布防参数不需要设置，不支持lHandle = hCNetSDK.NET_DVR_SetupAlarmChan_V41(lUserID, struAlarmParam);if (lHandle < 0) {System.out.println("NET_DVR_SetupAlarmChan_V41 error," + hCNetSDK.NET_DVR_GetLastError());hCNetSDK.NET_DVR_Logout(lUserID);hCNetSDK.NET_DVR_Cleanup();return;}System.out.println("设备ip:" + ip + "布防成功！");}
}
