配置opencv通过对话框显示图片

QString filename = QFileDialog::getOpenFileName(this,tr("open image"),"../",tr("Image File(*.png *.jpg *.jpeg *.bmp)")); if(filename == ""){

return;

}

cv::Mat image;

image = cv::imread(filename.toLatin1().data());//路径中不能有中文

cv::cvtColor(image,image,CV_BGR2RGB);

QImage img = QImage((const unsigned char *)(image.data),image.cols,image.rows,QImage::Format_RGB888);

ui->label->setPixmap(QPixmap::fromImage(img));

ui->label->resize(img.size());

ui->label->show();
