1.8安装大华相机SDK及测试

news/2025/2/23 3:11:25/

不同工业相机的sdk不同，可以到相应的官网下载，我使用的是大华相机

下载SDK：


官方下载地址：http://download.huaraytech.com/pub/sdk/
我使用的是2.2.5的Linux的x86的版本

点击下载

在这里插入图片描述
安装：


将下载的压缩包中.run文件提取出来，增加可执行权限，然后运行即可打开软件。

 压缩：unzip  [name]
更改文件权限：chmod u+x [name] （这里是添加可执行权限）
执行某个可执行程序，开始安装：sudo ./[name]
打开软件：找到软件的 .sh文件，从终端进入（输入.sh的路径）
安装默认位置：/opt/DahuaTech/MVviewer

测试：

打开大华的软件：

/opt/DahuaTech/MVviewer/bin/run.sh


成功打开MVviewer

在QT中使用大华相机


新建一个QT工程

导入OpenCV的头文件和库：
.pro文件中输入下列代码

INCLUDEPATH +=/usr/local/include/ \/usr/local/include/opencv4/ \/usr/local/include/opencv4/opencv2
LIBS +=/usr/local/lib/lib*



添加大华头文件和动态库：

刚才下载好的SDK在这个位置： 文件夹—其他位置—计算机  /opt/DahuaTech/MVviewer

将大华目录下的头文件 include 和动态库 lib 复制到qt工程文件夹下

在这里插入图片描述

 将这两个文件导入QT工程中：

在.pro文件中配置大华的环境

输入下列代码

INCLUDEPATH +=./include \LIBS += -L/opt/DahuaTech/MVviewer/lib/ -lMVSDK
LIBS += -L/opt/DahuaTech/MVviewer/lib/ -lImageConvert

添加测试代码

将我经常用的Camera和src的文件复制到工程文件夹下，并将其导入Qt工程中（没有的问我要，不想问我的用下面的代码测试）

这个工程有video.h,   video.cpp 和 main这三个文件

main函数：

#include <iostream>
#include "video.h"
#include<opencv2/opencv.hpp>
using namespace Dahua::GenICam;
using namespace Dahua::Infra;using namespace std;
using namespace cv;
int main()
{// 创建工业相机的实例Video v;if (!v.videoCheck()){printf("videoCheck failed!\n");return 0;}if (!v.videoOpen()){printf("videoOpen failed!\n");return 0;}//设置增益Video::ETrigType type = Video::ETrigType::trigContinous; //改为连续拉流v.CameraChangeTrig(type);                                //默认为软触发if (!v.videoStart()){printf("videoStart failed!\n");return 0;}Mat src;while(1){if(v.getFrame(src)){imshow("img",src);}else{printf("getFrame failed!\n");break;}if(waitKey(1)=='q'){break;}cout << "Hello World!" << endl;return 0;
}}
