本文主要是介绍Java 接入海康 SDK 云台控制,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
简介
Java 接入海康 SDK 设置 PTZ,主要实现云台基本控制和云台预置点两个功能:
云台基本控制:
NET_DVR_PTZControl
:云台控制操作(需先启动图象预览)NET_DVR_PTZControl_Other
:云台控制操作(不用启动图象预览)NET_DVR_PTZControlWithSpeed
:带速度的云台控制操作(需先启动图象预览)NET_DVR_PTZControlWithSpeed_Other
:带速度的云台控制操作(不用启动图象预览)
云台预置点功能:
NET_DVR_PTZPreset
:云台预置点操作(需先启动预览)NET_DVR_PTZPreset_Other
云台预置点操作(不用启动预览)
下载 SDK
首先,我们需要下载并安装海康SDK,并进行相关配置。具体步骤如下:
- 在海康威视官网下载 SDK 开发包,解压缩到本地目录
- 配置环境变量,将 SDK 的 bin 目录添加到系统的 PATH 环境变量中
- 在项目中引入SDK的jar包
下载SDK:https://open.hikvision.com/download/5cda567cf47ae80dd41a54b3?type=10&id=5cda5902f47ae80dd41a54b7
实现功能
添加依赖
在项目目录下新建 lib
文件夹,将下载的 SDK 开发包 库文件
里的 HCNetSDK.dll
、HCCore.dll
、HCNetSDKCom文件夹
、libssl-1_1.dll
、libcrypto-1_1.dll
、hlog.dll
、hpr.dll
、zlib1.dll
、PlayCtrl.dll
、SuperRender.dll
、AudioRender.dll
等文件均要加载到程序里面,HCNetSDKCom文件夹(包含里面的功能组件dll库文件)
需要和 HCNetSDK.dll
、HCCore.dll
一起加载,放在同一个目录下,且 HCNetSDKCom
文件夹名不能修改。
同时将 jna.jar
和 examples.jar
也放在 lib
目录下。
pom.xml
<dependency><groupId>com.sun</groupId><artifactId>jna</artifactId><version>1.0.0</version><scope>system</scope><systemPath>${project.basedir}/lib/jna.jar</systemPath>
</dependency>
<dependency><groupId>com.sun</groupId><artifactId>examples</artifactId><version>1.0.0</version><scope>system</scope><systemPath>${project.basedir}/lib/examples.jar</systemPath>
</dependency>
实现代码
SDK初始化
static HCNetSDK hCNetSDK = null;
static FExceptionCallBack_Imp fExceptionCallBack;static class FExceptionCallBack_Imp implements HCNetSDK.FExceptionCallBack {public void invoke(int dwType, int lUserID, int lHandle, Pointer pUser) {log.error("异常事件类型:{}", dwType);return;}

}

public static void logout(Integer lUserID) {if (Objects.nonNull(hCNetSDK) && Objects.nonNull(lUserID)) {hCNetSDK.NET_DVR_Logout(lUserID);hCNetSDK.NET_DVR_Cleanup();}
