在Qt下使用映美精黑白相机：Qt 5.12 + ImagingSource（映美精）+ vs2017 Community + OpenCV 3.3

最近应做一个视觉项目需要用到映美精相机，在网上搜索了很多资料没有找到相关内容，因此只能自己一步一步的摸索。

一、准备工作

相机型号：ImagingSource DMK 23G445

相机软件：ic_setup_3.4.0，gigecam_setup_3.6.0

其它软件：Qt 5.12.1， vs2017 Community， OpenCV 3.3.0

操作系统：Windows 10 1909 18363.592

Qt .pro配置文件如下（配置文件xxx换上电脑用户名）：

QT       += core guigreaterThan(QT_MAJOR_VERSION, 4): QT += widgetsTARGET = imagingSource_CallBack

Listener.h: 配置如下：

#ifndef LISTENER_H
#define LISTENER_H// Listener.h: interface for the CListener class.
//
// The CListener class is derived from GrabberListener. It overwrites
// the "frameReady()" method. In the frameReady method the member method
// "saveImage()" is called.
// "saveImage()" saves the specified buffer to a BMP file and calls a "Sleep(250)"
// to simulate a time expensive image processing. "saveImage()" is also called
// by the main() function of this example to save all buffers, that have
// not been processed in the frameReady method.#
//
// This class also overwrites the overlayCallback method to draw a
// frame counter.
//
// The CListener object is registered to a Grabber with the parameter
// eFRAMEREADY|eOVERLAYCALLBACK .
//
// If your camera resolution is not 1280 × 960, you should modify the
// macro definition "CAM_SIZE_X" and "CAM_SIZE_Y".
//
// You should change the "cmdhelper.h" path.
//#pragma once#include <QDebug>
#include <QLabel>
#include <QObject>#include <tisudshl.h>
#include "../cmdhelper.h" // TODO: You need change the path, the file path is usually as follows:// C:/Users/xxx/Documents/IC Imaging Control 3.4/samples/vc10/Common/cmdhelper.h#include <opencv2/core/core.hpp>

#define CAM_SIZE_Y 960      // TODO: Maybe you need modify the value.using namespace cv;
using namespace DShowLib;class CListener : public QObject, public DShowLib::GrabberListener

};#endif // LISTENER_H

Listener.cpp 配置如下

//
// Listener.cpp: implementation of the CListener class.
////#define _WIN32_WINNT 0x0500#include <iostream>
#include "Listener.h"//
/*! The overlayCallback() method draws the number of the current frame. Theframe count is a member of the tsMediaSampleDesc structure that is passedto overlayCallback() by the Grabber.*/

}//

{UNREFERENCED_PARAMETER(caller);emit deviceLost_Event();    // TODO: You need add the slot the process the signal.
}//
/*! Initialize the array of bools that is used to memorize, which buffers were processed inthe frameReady() method.

void CListener::setBufferSize( unsigned long NumBuffers )
{m_BufferWritten.resize( NumBuffers, false );
}//
/*! The image passed by the MemBuffer pointer is saved to a BMP file.*/
//void CListener::saveImage( smart_ptr<MemBuffer> pBuffer, DWORD currFrame)
//{
//    char filename[MAX_PATH];
//    if( currFrame < m_BufferWritten.size() )
//    {
//        sprintf( filename, "image%02i.bmp", currFrame );//        saveToFileBMP( *pBuffer, filename );//        m_BufferWritten.at( currFrame ) = true;
//    }
//}

在Qt项目中只要添加上面两个文件就可以啦，同时在要开始检测的地方要加入

addListener(pListener, GrabberListener::eALL); // 用法参见映美精参考文档

这样每次相机内存中有图片时，就能通过下面信号函数发送消息，在要处理图像的源文件中添加对应的槽就可以了。

frameReady_Event();

如果采用软触发建议使用 snapImage() 函数取图。
