1、Mat转换为QImage

QImage Mat2QImage(const Mat& mat)

{



Mat rgb;



cvtColor(mat, rgb, CV_BGR2RGB);



return QImage((const unsigned char*)(rgb.data), rgb.cols, rgb.rows, QImage::Format_RGB888);

}

2、QImage转换为 Mat

Mat QImage2Mat(const QImage& qimage)

{



Mat mat = Mat(qimage.height(), qimage.width(), CV_8UC4, (uchar*)qimage.bits(), qimage.bytesPerLine());



Mat mat2 = Mat(mat.rows, mat.cols, CV_8UC3 );



int from_to[] = { 0,0, 1,1, 2,2 };



mixChannels( &mat, 1, &mat2, 1, from_to, 3 );



return mat2;

}
