尝试在qtcreator上使用opencv实现canny edge

Question

我正在尝试使用qtgui中的opencv函数将图像转换为canny图像。当我按下gui按钮将原始图像转换为canny时，程序在发布时崩溃，但在调试模式下显示错误R6010。

void MainWindow::edgeImage()
    {
    IplImage *image1 =cvLoadImage("Desert.jpg");
    IplImage *Gray = cvCreateImage( cvGetSize(image1), IPL_DEPTH_8U, 1 );
    cvCvtColor(image1, Gray, CV_RGB2GRAY);
    IplImage *Edge = cvCreateImage( cvGetSize(image1), IPL_DEPTH_8U, 1 );
    cvCanny( Gray, Edge, 10, 100 );
    ui->label_2->setPixmap(QPixmap::fromImage(*IplImage2QImage(Edge))  ;           
    }

提前感谢您的

我对其完美工作的做了一些小改动

void MainWindow::edgeImage()
{
image =cvLoadImage(FileName.toLocal8Bit().data());
Gray = cvCreateImage(cvSize(image->width,image->height),IPL_DEPTH_8U,1 );
cvCvtColor(image, Gray, CV_RGB2GRAY);
canny= cvCreateImage(cvSize(image->width,image->height),IPL_DEPTH_8U,1 );
cvCanny(Gray,canny,50,150,3);
QImage imgCanny = QImage((const unsigned char*)canny->imageData,canny->width,canny->height,QImage::Format_Indexed8);
imgCanny.setPixel(0,0,qRgb(0,0,0));
ui->label_3->setPixmap(QPixmap::fromImage(imgCanny).scaled(ui->label_3->size()));
}
