c++ - opencv-3.0.0 ubuntu 14.04 "nonfree/nonfree.hpp"构建错误

Question

我正在尝试在 opencv-3.0.0 中实现 SURF 算法为此，我包含了头文件

#include <stdio.h>
#include <iostream>
#include "opencv2/core.hpp"
#include "opencv2/features2d.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/calib3d.hpp"
#include "opencv2/xfeatures2d.hpp"
#include "opencv2/calib3d.hpp"
#include <opencv2/nonfree/nonfree.hpp>
using namespace cv;
using namespace std;

但我不断收到下面提到的错误。我试过到处搜索但找不到任何解决方案。我已经构建了带有额外依赖项的 opencv 模块。

编辑 1所以，我实际面临的问题是我试图使用正在开发中的软件包而不是稳定版本。我只需要执行 git checkout 3.0.0 即可获得稳定版本。

打开位于/usr/include/opencv2/nonfree/features2d.hpp 的文件 features2d.hpp你应该是一个 sudo usr 来编辑文件。将“vector”头文件添加为#include 然后添加 using namespace std;

这应该可以解决您的问题。问候，阿维纳什
