Problem Description:
Recently, when learning integrated navigation, Ubuntu 20 + opencv4.0 was used. When compiling logo-beam, the following error messages were encountered:
10: fatal error: opencv/CV. H: no such file or directory
13 |#include & lt; opencv/cv.h>
Solution:
This is caused by the version change of OpenCV library. Put #include & lt; opencv/cv.h> Replace with #include & lt; opencv2/opencv.hpp> Just.
