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0
    public static final int DA_HUA_SUB_CHANNEL = 0;
	//	登录状态 默认false 当登录成功后true
    public static boolean DA_HUA_LOGIN_STATE = false;
	//	自定义状态
    public static boolean DA_HUA_SUB_STATE = false;

        DaHuaConstantConfig.DA_HUA_LOGIN_STATE = true;

        // 断线后需要重新订阅

        ExecutorService service = Executors.newSingleThreadExecutor();
        service.execute(new Runnable() {

DaHuaNetSdkManCountThread.java 创建连接的线程类

    }

    // 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)) {

                    log.info("da-hua-sdk human number open:");
                    DaHuaConstantConfig.DA_HUA_SUB_STATE = true;
                } else {
                    DaHuaConstantConfig.DA_HUA_SUB_STATE = false;
                }
            }
            return true;

放在SpringBoot启动页面内启动

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

启动后控制台输出
