使用opencv2.3 imread无法读取图像 [英] Can not read image with opencv2.3 imread

问题描述

您好，我想通过使用opencv的imread函数读取图像在链接（http://opencv.itseez.com/doc/tutorials/introduction/display_image/display_image.html#display-image）。我有VS2010与64位窗口7.每次我尝试我得到错误消息无图像数据，但我想要读取的图像是在同一文件夹中的代码。有人可以帮助我如何读取图像的imread函数？我的代码如下：

  #includestdafx.h
 #include< cv.h> 
 #include< highgui.h> 
 using namespace cv; 
 
 int _tmain（int argc，_TCHAR * argv []）
 {
 Mat image; 
 image = imread（al.jpg）; 
 if（argc！= 2 ||！image.data）
 {
 printf（no image data \\\
）; 
 return -1; 
} 
 namedWindow（Display Image，CV_WINDOW_AUTOSIZE）; 
 imshow（Display Image，image）; 
 waitKey（0）; 
 return 0; 
} 
  

解决方案

  IplImage * img = cvLoadImage（Image_Name）; 
  p> 
 
 
然后你可以将它转换为cv :: Mat using，
  Mat mat（img）; 
  
 
Hello I am trying to read an image by using imread function of opencv as in the link  (http://opencv.itseez.com/doc/tutorials/introduction/display_image/display_image.html#display-image). I have VS2010 with 64 bit windows 7. Each time I try I get error message "no image data", however the image I want to read is in the same folder with codes. Can someone please help me how to read an image with imread function? My code is as below:
#include "stdafx.h"
#include <cv.h>
#include <highgui.h>
using namespace cv;

int _tmain(int argc, _TCHAR* argv[])
{
    Mat image;  
    image = imread("al.jpg");
    if(argc != 2 || !image.data )
    {
        printf("no image data \n");
        return -1;
    }
    namedWindow("Display Image", CV_WINDOW_AUTOSIZE);
    imshow("Display Image", image);
    waitKey(0);
    return 0;
}

解决方案
It you can load image using
IplImage *img=cvLoadImage("Image_Name);
Then you can convert this into cv::Mat using,
Mat mat(img);
