# 一、软硬件介绍 #

**Basler spL4096-140km Camera Link 相机**

Basler相机

图像采集卡

软件运行平台是Win7 64位电脑，Qt版本是msvc2015 64位  Debug版本。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpc3Nnb29kYnllMjAxMg_size_16_color_FFFFFF_t_70 2][]

# 二、Qt中导入MIL库 #

需要注意的是，如果你没有购买MIL库，会报错提示。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpc3Nnb29kYnllMjAxMg_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpc3Nnb29kYnllMjAxMg_size_16_color_FFFFFF_t_70 4][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2tpc3Nnb29kYnllMjAxMg_size_16_color_FFFFFF_t_70 5][]

**导入步骤：**

将MIL库放在工程目录下，并在pro文件中写入如下代码。

#依赖freeglut库以及头文件
    INCLUDEPATH += $$PWD/MIL/Include
    LIBS += -L$$PWD/MIL/LIB  -lMil

使用时，在文件中添加如下代码。

#pragma comment(lib, "mil.lib")
    #include <mil.h>

# 三、相机的默认配置，DCF文件的使用 #

对相机采集卡的设置在dcf文件中，当程序在初始化各种内存时使用默认时，是按照默认dcf文件进行初始化的。

//分配默认的应用、系统
    MappAllocDefault(M_DEFAULT, &MilApplication, &MilSystem, M_NULL, &MilDigitizer, &MilImage);

上面的这句代码，按照默认DCF文件来初始化了应用，系统，相机和图像BUFFER，没有初始化显示器。

**注意：如果没有软件配置默认的DCF文件，就会出现即使没有开启相机依然能采到如下图像的情况。这个图像在连续采集的时候，会不断向左移动，亮度从暗到亮不断刷新。**

**\*\*\*正确的方法是在MIL Config软件中，配置默认的DCF文件**

**如下面两张图所示，第一张图是MIL Config的入口（左下角第一行的蓝色字体）；第二张图是配置默认的DCF文件（先用官方软件配置好需要用的DCF文件）**

# 四、MIL和Qt之间的数据转换 #

## 4.1 MIL\_INT转Int ##

MIL_INT BufSizeX=0;
    MIL_INT BufSizeY=0;
    
    //获得相机图像的宽度和高度
    MdigInquire(MilDigitizer, M_SIZE_X,&BufSizeX);
    MdigInquire(MilDigitizer, M_SIZE_Y,&BufSizeY);
    
    //MIL_INT转换为Int类型，并在Qt的控件中显示
    int tempintx=BufSizeX;
    int tempinty=BufSizeY;
    QString tempstr="图像的宽和高：";
    tempstr=tempstr+QString::number(tempintx)+"   "+QString::number(tempinty);
    ui->DebugText->append(tempstr);

## 4.2 QString转MIL中的TEXT ##

//保存图像
    ui->DebugText->append("保存第"+QString::number(index)+"张图像");
    QString savepath=ui->lineEdit->text();
    savepath=savepath.append("/"+QString::number(index));
    savepath=savepath.append(".tif");
    const wchar_t* savepath_wchar = reinterpret_cast<const wchar_t *>(savepath.utf16());
    MbufSave(savepath_wchar,MilImage);

## 4.3 获取相机采集的图像 ##

//图像数据地址
    void  *SrcImageDataPtr = NULL;
    void  *PhysicsImagePtr = NULL;
    //相机图像的属性信息
    MIL_INT SrcImageDataSize=0;
    MIL_INT BufSizeX=0;
    MIL_INT BufSizeY=0;
    
    //定义图像格式
    QImage::Format format = QImage::Format_Indexed8;
    int m_iWidth=BufSizeX;
    int m_iHeight=BufSizeY;
    //定义QImage对象
    QImage img = QImage(m_iWidth,m_iHeight,format);//后面设置为定值
    
    //获取相机图像Buffer中的图像信息
    MbufInquire(MilImage, M_HOST_ADDRESS, &SrcImageDataPtr);//数据指针
    MbufInquire(MilImage,M_PHYSICAL_ADDRESS,&PhysicsImagePtr);//数据物理地址指针，仅供主线意外的
    
    MbufInquire(MilImage, M_SIZE_BYTE, &SrcImageDataSize);//数据大小
    MbufInquire(MilImage,M_SIZE_X,&BufSizeX);
    MbufInquire(MilImage,M_SIZE_Y,&BufSizeY);
    
    //将图像数据拷贝到QImage中
    memcpy(img.bits(),SrcImageDataPtr,SrcImageDataSize);

## 4.4 程序运行时间计时器 ##

//抓取图像数量指示
    MIL_DOUBLE  Time = 0.0;//运行总时间
    
    //重置计时器
    MappTimer(M_DEFAULT, M_TIMER_RESET+M_SYNCHRONOUS, M_NULL);
    
    //记录时间,计算帧率
    MappTimer(M_DEFAULT, M_TIMER_READ + M_SYNCHRONOUS, &Time);//记录当前运行时间
    double temprate=Framecount / Time;//计算每秒触发采集多少张图片
    ui->lineEdit_FrameRate->setText(QString::number(temprate,10,4));//在主页面显示帧率

##  4.5 存储图片到硬盘 ##

//保存图像
    //定义保存图片的路径和名称
    QString savepath2="D:\\output_image";
    savepath2=savepath2.append("/"+QString::number(num*10000+n*100+i));
    savepath2=savepath2.append(".tif");
    
    //将路径和名称转换为MIL的字符串类型
    const wchar_t* savepath_wchar = reinterpret_cast<const wchar_t *>(savepath2.utf16());
    //将MilImage[n*100+i]保存在路径下
    MbufSave(savepath_wchar,MilImage[n*100+i]);
    savepath2.clear();

# 五 连续采集图像，并在MIL自带显示器上显示 #

只要移植MIL库正确，只需要如下两句，即可显示实时图像

MappAllocDefault(M_DEFAULT, &MilApplication, &MilSystem, &MilDisplay,&MilDigitizer, &MilImageDisp);
    MdigGrabContinuous(MilDigitizer, MilImageDisp);

# 六 外部电压触发采集，方波 #

例子：一般100KHz的方波输入，一张图像4096\*1000个像素，按应该是100帧每秒

**由于线扫相机，每次采集的是一行，即4096\*1个像素的图像。所以100KHz即每秒采集100K行。**

需要如下函数等待触发采集完成

MdigGrabWait(MilDigitizer, M_GRAB_END);//等待触发抓取完成

触发采集的图像会存储在MilImage\[n\*100+NbProc\] 中

MdigGrab(MilDigitizer, MilImage[n*100+NbProc]);//在 第n个内存块的第NbProc个内存区域 抓取数据

//前期准备工作如下*********************************************************
    //存放触发抓取图像的内存空间
    MIL_ID     MilImage[200];
    
    //每次触发抓取后调用的用户函数
    MIL_INT MFTYPE GrabStart(MIL_INT, MIL_ID, void*);
    
    //定义触发的用户数据
    typedef struct
    {
        MIL_INT     NbGrabStart;
    } UserDataStruct;
    
    //相机图像的属性信息
    MIL_INT SrcImageDataSize;
    MIL_INT BufSizeX;
    MIL_INT BufSizeY;
    
    //开始分配内存*********************************************************
    //按照默认的DCF文件，初始化各类ID
    MappAllocDefault(M_DEFAULT, &MilApplication, &MilSystem, M_NULL,&MilDigitizer, &MilImageDisp);
    
    //分配抓取的图像内存
    for (int n=0; n<200; n++)
        MbufAlloc2d(MilSystem,
                    MdigInquire(MilDigitizer, M_SIZE_X, M_NULL),
                    MdigInquire(MilDigitizer, M_SIZE_Y, M_NULL),
                    8L+M_UNSIGNED,
                    M_DISP+M_IMAGE+M_GRAB+M_PROC, &MilImage[n]);
    
    //开始触发抓取设置和抓取图像*********************************************************
    //定义触发事件函数
    UserDataStruct UserStruct;//定义触发的 用户数据
    UserStruct.NbGrabStart = 0;
    //关联触发函数
    MdigHookFunction(MilDigitizer, M_GRAB_START, GrabStart, (void *)(&UserStruct));
    //设置抓取是同步模式
    MdigControl(MilDigitizer, M_GRAB_MODE, M_ASYNCHRONOUS);
    
    //抓取第一个图像，获取图像属性信息
    MdigGrab(MilDigitizer, MilImage[0]);
    //相机图像的属性信息
    SrcImageDataSize=0;//图像的大小，单位像素
    BufSizeX=0;//图像的宽度
    BufSizeY=0;//图像的高度
    //获得相机图像的宽度和高度
    MdigInquire(MilDigitizer, M_SIZE_X,&BufSizeX);
    MdigInquire(MilDigitizer, M_SIZE_Y,&BufSizeY);
    MbufInquire(MilImage[0], M_SIZE_BYTE, &SrcImageDataSize);//数据大小
    
    //连续抓取图像
    n=0;//初始化从第0个内存块开始采集
    NbProc = 0;//从内存块的第0个位置开始采集
    int Framecount=0;//图像的总张数
    int Framenum=1;//使用过内存块的次数
    //重置计时器
    MappTimer(M_DEFAULT, M_TIMER_RESET+M_SYNCHRONOUS, M_NULL);
    
    do {
            //抓取下一个图像
            MdigGrab(MilDigitizer, MilImage[n*100+NbProc]);//在 第n个内存块的第NbProc个内存区域 抓取数据
            MdigGrabWait(MilDigitizer, M_GRAB_END);//等待触发抓取完成
    
            //将图像传递给显示器，这里我是在界面窗口直接显示，没有用MIL自带的显示器
            //MimArith(MilImage[n*100+NbProc], M_NULL, MilImageDisp, M_PASS);//取反M_OR
    
            //更新处理的图像数
            NbProc++;//下一个图像内存空间
            Framecount++;//总图像数加1
    
            //如果点击了关闭采集，退出循环
            if(FlagCapture==0)
            {
                break;
            }
    
            //每采集200张计算一下帧率
            if(Framecount%200==0)
            {
                //记录时间,计算帧率
                MappTimer(M_DEFAULT, M_TIMER_READ + M_SYNCHRONOUS, &Time);//记录当前运行时间
                double temprate=Framecount / Time;//计算每秒触发采集多少张图片

                QCoreApplication::processEvents();
            }
    
            //如果抓取的图像数量达到了一个内存块的长度，换到下一个内存块。并启动线程存储当前内存块抓取的所有图像
    //这一段是我自己所需的
            if(NbProc>=100)//一个内存块可以抓取100张图片
            {
                //如果抓取的图像总数量还没有达到限制数量，传递信息到存储线程中，开始存储图像
                if(Framenum<=MaxNum)
                {
                    //发送信号到存储线程
                    emit SendData(savepath,n,NbProc,Framenum);
                }
                NbProc=0;//重新 从第0个内存位置开始存储
                n = 1-n;//转换内存块
                Framenum++;//使用过内存块的次数加1
            }
        }
        while(!MosKbhit());

    QString savepath=ui->lineEdit->text();
    savepath=savepath.append("/"+QString::number(index));
    savepath=savepath.append(".tif");
