对于Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /home/cc/software/opencv-3.4.1/modules/highgui/src/window.cpp……报错的解决方法

代码如下：

 1 #include <iostream>
 2 #include <opencv2/highgui/highgui.hpp>
 3 #include <opencv2/opencv.hpp>
 4 
 5 using namespace std;
 6 
 7 int main()
 8 {
 9     cv::Mat srcImage=cv::imread("lena.jpg");
10     imshow("源图像",srcImage);
11     cv::waitKey(0);
12     return 0;
13 }

cmake以后报错：

　　OpenCV(3.4.1) Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /home/cc/software/opencv-3.4.1/modules/highgui/src/window.cpp, line 356
terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(3.4.1) /home/cc/software/opencv-3.4.1/modules/highgui/src/window.cpp:356: error: (-215) size.width>0 && size.height>0 in function imshow

已放弃 (核心已转储)

解决方法：

　　把图像的路径替换成绝对路径，问题解决.

　　例如我的写为：cv::Mat srcImage=cv::imread("/home/cc/test/opencv_project/lena.jpg");
