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;

}
