MFC调用HALCON实现相机采图和图像显示

一、相机采图

1、查询设备信息

HTuple Information, Values;

info_framegrabber("GigEVision", "device", &Information, &Values);

Information用来获取相机信息

Values用来获取相机名称

2、打开相机

HTuple m_hFrameGrabber; //相机句柄

open_framegrabber("GigEVision",0,0,0,0,0,0,"progressive",-1,"default",

-1,"false","default",Values[0],0,-1,&m_hFrameGrabber);

打开第二个相机

open_framegrabber("GigEVision",0,0,0,0,0,0,"progressive",-1,"default",

-1,"false","default",Values[1],0,-1,&m_hFrameGrabber);

注意相机名的调用方法。

3、获取相机参数

HTuple m_ImageWidth;

get_framegrabber_param(m_hFrameGrabber,"m_ImageWidth",&m_ImageWidth);

4、单帧抓取

Hobject * pImage; //图片指针

grab_image(pImage,m_hFrameGrabber);

由于grab_image函数不能中断执行，因此在多线程中调用时，需
