问题描述
我已使用此链接在ubuntu上安装了OpenCV，并且我正在尝试使用SURF描述符.我知道他们将这些类型的描述符的位置更改为nonfree模块，因此我们需要将其包括在内，如下所示:#include "opencv2/nonfree/features2d.hpp".问题是我在编译时遇到此错误:opencv2/nonfree/features2d.hpp no such file or directory.
I've installed OpenCV on ubuntu using this link and I'm trying to use SURF descriptor. I knew that they changed the location of these type of descriptors to the nonfree module so we need to include it, which is something like this: #include "opencv2/nonfree/features2d.hpp". The problem is that I'm getting this error at compile time: opencv2/nonfree/features2d.hpp no such file or directory.
有什么想法要解决吗?
已编辑:openCV的其他部分工作正常.我包括以下库，一切看起来都很好:
EDITED:The other parts of openCV are working fine. I'm including the following libraries and everything is looking good:
#include "opencv2/core/core.hpp"
#include "opencv2/features2d/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/calib3d/calib3d.hpp"
#include "opencv2/legacy/legacy.hpp"
我检查了OpenCV目录中的inlcude文件夹，那里是nonfree文件夹.而且，它是我无法在QTCreator(我正在使用的环境)中访问的唯一库，因为我尝试包括在Inlcude文件夹中找到的所有其他库，而且它们看起来不错.
I checked the inlcude folder in my OpenCV directory and the nonfree folder is there. Moreover, it's the only library that I can't access within QTCreator (The environment I'm using) because I tried to include all the other librairies found in the Inlcude folder and they looked good.
EDITED2:您可以在此上运行make VERBOSE=1时看到的截图链接
EDITED2:You can see a screenshot of what I saw when I ran make VERBOSE=1 on this link
所以不确定在哪里看?实际上，我在../usr/include/opencv2/
So not sure where to look? Actually, I did not find the nonfree folder in ../usr/include/opencv2/
谢谢.
推荐答案
实际上，我只是使用以下命令更新了openCV，然后它起作用了:
Actually, I just updated openCV using the following commands then it worked:
sudo add-apt-repository --yes ppa:xqms/opencv-nonfree
sudo apt-get update
sudo apt-get install libopencv-nonfree-dev
