使用大华惠智双目半球网络摄像机DH-IPC-HD4140X-E2获取人流量统计数据

记录一下使用Java的SpringBoot+大华SDK在智慧公厕项目中使大华惠智双目半球网络摄像机DH-IPC-HD4140X-E2获取人流量统计数据

首先根据说明书登录摄像头，一般摄像头都有自己的账号和密码(可能是admin admin 也可能是admin 888888 还有可能是admin 12345)，有IP的(可能是192.168.1.108)，在同一个网段内浏览器访问摄像头的IP就可以访问web页面

使用windows系统自带的浏览器Microsoft Edge 谷歌浏览器也可以，主要是要安装插件


下载安装插件(如果电脑之前安装过就可以不用安装)



安装完成之后 重启浏览器登录(更保险)
可能有提示要加载，那就允许



设置人流量统计的相关参数
首先在设置 智能方案里把图标点亮

在设置-人数统计里选择人数统计

绘制区域和绘制方向线 绘制区域表示人流统计的区域，只有这个区域内的才统计的，绘制方向线，这个默认是入的方向线
参数设置进入和离开人数需要打钩，灵敏度这个的配置需要根据实际来确认 人数统计报警的进入人数和离开人数需要设置成1，滞留人数不需要设置(这样用程序去监听的时候就能被动获取报警数据)


布撤防配置

标定配置 安装高度和安装角度

自动维护配置 这个很关键，必须要配置，不然这个摄像头运行时间过长会被卡死的，可能是数据满了

网络设置 根据实际需求设置IP地址

首先去官网拿到开发需要的SDK

https://support.dahuatech.com/tools/sdkExploit

新建一个SpringBoot项目后调用sdk，在这里使用的是win10 64位的，sdk需要重新封装，去除gui方面的那部分代码
SpringBoot调用sdk的核心代码

DaHuaConstantConfig .java

public class DaHuaConstantConfig {//	摄像头的IP地址public static final String DA_HUA_IP= "192.168.1.108";//	摄像头的获取人流数据的端口是37777 不是80端口 这里有坑public static final int DA_HUA_PORT = 37777;//	登录的账号public static final String DA_HUA_ADMIN = "admin";//	登录的密码public static final String DA_HUA_PASSWORD = "admin";//	通道 默认0public static final int DA_HUA_SUB_CHANNEL = 0;//	登录状态 默认false 当登录成功后truepublic static boolean DA_HUA_LOGIN_STATE = false;//	自定义状态public static boolean DA_HUA_SUB_STATE = false;
}

DaHuaDisConnectCallBack.java

import com.netsdk.lib.NetSDKLib;
import com.sun.jna.Pointer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;//  设备断线回调: 通过 CLIENT_Init 设置该回调函数，当设备出现断线时，SDK会调用该函数public class DaHuaDisConnectCallBack implements NetSDKLib.fDisConnect {private final Logger log =  LoggerFactory.getLogger(this.getClass());public void invoke(NetSDKLib.LLong m_hLoginHandle, String pchDVRIP, int nDVRPort, Pointer dwUser) {log.error("Device:"+pchDVRIP+"Port:"+nDVRPort+"-DisConnectCallBack");DaHuaConstantConfig.DA_HUA_LOGIN_STATE = false;DaHuaConstantConfig.DA_HUA_SUB_STATE = false;// 断线提示}}

DaHuaHaveReConnectCallBack.java

import com.netsdk.demo.module.VideoStateSummaryModule;
import com.netsdk.lib.NetSDKLib;
import com.sun.jna.Pointer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;// 网络连接恢复，设备重连成功回调
// 通过 CLIENT_SetAutoReconnect 设置该回调函数，当已断线的设备重连成功时，SDK会调用该函数public class DaHuaHaveReConnectCallBack implements NetSDKLib.fHaveReConnect {private final Logger log =  LoggerFactory.getLogger(this.getClass());public void invoke(NetSDKLib.LLong m_hLoginHandle, String pchDVRIP, int nDVRPort, Pointer dwUser) {log.error("ReConnect Device[%s] Port[%d]\n", pchDVRIP, nDVRPort);DaHuaConstantConfig.DA_HUA_LOGIN_STATE = true;// 断线后需要重新订阅ExecutorService service = Executors.newSingleThreadExecutor();service.execute(new Runnable() {@Overridepublic void run() {log.warn("Reconnect Device ReAttache next");if (VideoStateSummaryModule.getM_hAttachMap().size() > 0) {   // 如果断前正在订阅// 重订阅事件log.warn("Reconnect Device ReAttache need");VideoStateSummaryModule.reAttachAllVideoStatSummary(DaHuaNetSdkManCountThread.humanNumberStatisticCB);DaHuaConstantConfig.DA_HUA_SUB_STATE = true;}}});service.shutdown();}
}

DaHuaHumanNumberStatisticCallBack .java

import com.netsdk.lib.NetSDKLib;
import com.sun.jna.Pointer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;import java.io.IOException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;// 人流统计数据回调
public class DaHuaHumanNumberStatisticCallBack implements NetSDKLib.fVideoStatSumCallBack {private final Logger log =  LoggerFactory.getLogger(this.getClass());public void invoke(NetSDKLib.LLong lAttachHandle, NetSDKLib.NET_VIDEOSTAT_SUMMARY stVideoState, int dwBufLen, Pointer dwUser) throws ParseException {try {//	 自定义接收的类CsRecordHumanNumber csRecordHumanNumber = new CsRecordHumanNumber();csRecordHumanNumber.setEnteredToday(stVideoState.stuEnteredSubtotal.nToday); // 当日进入的人数csRecordHumanNumber.setEnteredHour(stVideoState.stuEnteredSubtotal.nHour);// 单位小时内进入的人数csRecordHumanNumber.setEnteredTotal(stVideoState.stuEnteredSubtotal.nTotal);// 设备运行后进入的总人数csRecordHumanNumber.setExitedToday(stVideoState.stuExitedSubtotal.nToday);// 当日出去的人数csRecordHumanNumber.setExitedHour(stVideoState.stuExitedSubtotal.nHour);// 单位小时内出去的人数csRecordHumanNumber.setExitedTotal(stVideoState.stuExitedSubtotal.nTotal);//	设备运行后出去的总人数log.info(csRecordHumanNumber.toString());// to do 把数据传给Spring去插入数据库或者其他处理} catch (IOException e) {e.printStackTrace();}}}

DaHuaNetSdkManCountThread.java 创建连接的线程类

import com.netsdk.demo.module.LoginModule;
import com.netsdk.demo.module.VideoStateSummaryModule;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;public class DaHuaNetSdkManCountThread extends Thread {private static final Logger log =  LoggerFactory.getLogger(DaHuaNetSdkManCountThread.class);// 设备断线通知回调private static final DaHuaDisConnectCallBack disConnectCB = new DaHuaDisConnectCallBack();// 网络连接恢复private static final DaHuaHaveReConnectCallBack haveReConnectCB = new DaHuaHaveReConnectCallBack();// 人数统计回调事件public static DaHuaHumanNumberStatisticCallBack humanNumberStatisticCB = new DaHuaHumanNumberStatisticCallBack();public void run(){System.out.println(Thread.currentThread().getName()+" NetSdk");if(LoginModule.init(disConnectCB, haveReConnectCB)){login();}}// 登录public static boolean login() {if (LoginModule.login(DaHuaConstantConfig.DA_HUA_IP, DaHuaConstantConfig.DA_HUA_PORT, DaHuaConstantConfig.DA_HUA_ADMIN, DaHuaConstantConfig.DA_HUA_PASSWORD)) {int chanNum = LoginModule.m_stDeviceInfo.byChanNum;log.info("da-hua-sdk-login success:"+chanNum);DaHuaConstantConfig.DA_HUA_LOGIN_STATE = true;if (!VideoStateSummaryModule.channelAttached(DaHuaConstantConfig.DA_HUA_SUB_CHANNEL)) {if (VideoStateSummaryModule.attachVideoStatSummary(DaHuaConstantConfig.DA_HUA_SUB_CHANNEL, humanNumberStatisticCB)) {log.info("da-hua-sdk human number open:");DaHuaConstantConfig.DA_HUA_SUB_STATE = true;} else {DaHuaConstantConfig.DA_HUA_SUB_STATE = false;}}return true;}return false;}
}

放在SpringBoot启动页面内启动

DaHuaNetSdkManCountThread daHuaNetSdkManCountThread = new DaHuaNetSdkManCountThread();
daHuaNetSdkManCountThread.start();

启动后控制台输出
