QImage来转换图像QImageWidget::Mat2QImage(cv::Matconst&src){cv::Mattemp;//makethesamecv::MatcvtColor(src,temp,CV_BGR2RGB

图像加载函数intbase::loadImg(Mat&mat,QLabel*labelImage){cvtColor(mat,mat,CV_BGR2RGB);QImage::FormatimgFormat

lib-lopencv_imgcodecs-lopencv_core-lopencv_highgui-lopencv_imgproc-lopencv_videoio实际只要添加-lopencv_imgproc就行，CV_BGR2RGB

1、cv::cvtColor(mat,mat,CV_BGR2RGB);报错：CV_BGR2RGB未定义的标识符处理方法：添加头文件#include"opencv2/imgproc/types_c.h"2

opencvMat与QtQImage相互转换QImageWidget::Mat2QImage(cv::Matconst&src){cv::Mattemp;cvtColor(src,temp,CV_BGR2RGB

Mat转QImageMatmat=imread("c:/dev/test.jpg");cvtColor(mat,mat,CV_BGR2RGB);QImageimage(mat.data,mat.cols

Matm;m=imread("F:\\1.png");cvtColor(m,m,CV_BGR2RGB);QImageimag

C++QStringsss="path";cv::Matimg=cv::imread(sss.toStdString());cv::cvtColor(img,img,CV_BGR2RGB);//inyourcodecv2

矩阵和tensor相互转换cvmat到tensortips:这里主要要注意的就是在opencv和pytorch中存储顺序的差异cv::cvtColor(frame,frame,CV_BGR2RGB);/

IplImage[cpp]viewplaincopyQImage*IplImageToQImage(constIplImage*img){QImage*image;cvCvtColor(img,img,CV_BGR2RGB

Mat转QImageMatmat=imread("c:/dev/test.jpg");cvtColor(mat,mat,CV_BGR2RGB);QImageimage(mat.data,mat.cols

QImage型图像staticQImageMat2QImage(cv::Mat&image){QImageimg;if(image.channels()==3){cvtColor(image,image,CV_BGR2RGB

QLabel上显示Mat图像voidshowMat(Matmat){Matrgb;QImageimg;if(mat.channels()==3)//RGBimage{cvtColor(mat,rgb,CV_BGR2RGB

QLabel上显示Mat图像voidshowMat(Matmat){Matrgb;QImageimg;if(mat.channels()==3)//RGBimage{cvtColor(mat,rgb,CV_BGR2RGB

上显示Mat图像voidshowMat(Matmat) { Matrgb; QImageimg; if(mat.channels()==3)//RGBimage { cvtColor(mat,rgb,CV_BGR2RGB

1、Mat转换为QImageQImageMat2QImage(constMat&mat){Matrgb;cvtColor(mat,rgb,CV_BGR2RGB);returnQImage((constunsignedchar

1、Mat转换为QImageQImageMat2QImage(constMat&mat){Matrgb;cvtColor(mat,rgb,CV_BGR2RGB);  returnQImage((constunsignedchar

/image/aa.jpg"); cvtColor(img,img,CV_BGR2RGB); qimg=new
