大华sdk Java无画面 大华sdk客户端

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
文中提到的例程的Camera和src的代码在文尾（有兴趣可以参考）

下载：

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

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

安装位置：/opt/DahuaTech/MVviewer

测试：

运行启动脚本：/opt/DahuaTech/MVviewer/bin/run.sh

成功打开MVviewer

QT使用大华：

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：

将大华目录下的头文件复制到工程文件夹下

导入QT：

pro文件中输入下列代码

INCLUDEPATH +=./include \

LIBS += -L/opt/DahuaTech/MVviewer/lib/ -lMVSDK
LIBS += -L/opt/DahuaTech/MVviewer/lib/ -lImageConvert
LIBS += -L/opt/DahuaTech/MVviewer/lib/ -lVideoRender
LIBS += -L/opt/DahuaTech/MVviewer/lib/GenICam/bin/Linux64_x64/ -lGCBase_gcc421_v3_0 -lGenApi_gcc421_v3_0 -lLog_gcc421_v3_0
LIBS += -L/opt/DahuaTech/MVviewer/lib/GenICam/bin/Linux64_x64/ -llog4cpp_gcc421_v3_0 -lNodeMapData_gcc421_v3_0 -lXmlParser_gcc421_v3_0
LIBS += -L/opt/DahuaTech/MVviewer/lib/GenICam/bin/Linux64_x64/ -lMathParser_gcc421_v3_0

大华动态库：

添加动态库文件的一般方法：

添加动态库，如libMVSDK.so文件
LIBS+=-L/opt/DahuaTech/MVviewer/lib -lMVSDK
//注意：最前面加上大写字母L。将文件名中的lib替换成-l

添加测试代码：

将例程下的env_test中Camera和src复制到工程文件夹下

将其导入Qt

修改主函数：

#include <iostream>
#include "Camera/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;
}

}

插入大华相机，运行，显示设备信息即成功

完成
