关于QImage和IplImage之间转换的实现

在嵌入式系统中实现qt和opencv的处理，最基础的就是QImage和IplImage之间的转换。这样两者就可以进行一起使用图像数据，从而达到利用qt显示和利用opencv处理的功能。



下面我将贴出代码：



QImage ----->> IplImage



[cpp]
view plaincopy

QImage *IplImageToQImage(const IplImage *img)
{
QImage *image;
cvCvtColor(img,img,CV_BGR2RGB);
uchar *imgData=(uchar *)img->imageData;
image=new QImage(imgData,img->width,img->height,QImage::Format_RGB888);
return image;
}




IplImage ------->>QImage



[cpp]
view plaincopy

IplImage *QImageToIplImage(const QImage * qImage)
{
int width = qImage->width();
int height = qImage->height();
CvSize Size;
Size.height = height;
Size.width = width;
IplImage *IplImageBuffer = cvCreateImage(Size, IPL_DEPTH_8U, 3);
for (int y = 0; y < height; ++y)
{
for (int x = 0; x < width; ++x)
{
QRgb rgb = qImage->pixel(x, y);
cvSet2D(IplImageBuffer, y, x, CV_RGB(qRed(rgb), qGreen(rgb), qBlue(rgb)));
}
}
return IplImageBuffer;
}
