在Qt的QGraphicsView中显示OpenCV的iplimage图片

IplImage2QImage（）函数见：iplImage to QImage

//显示图片

scene=new QGraphicsScene(this);//在构造函数里处理

voidALPR_demo::disp_iplimage(IplImage*iplimage,QGraphicsView*gv)

{

//转换

QImageqImage=opencv_tools.IplImage2QImage(iplimage);

if(!qImage.isNull()){

//调整大小

 

scene->clear();

 

scene->addPixmap(QPixmap::fromImage(qImage));

gv->setScene(scene);

}

}
