在OpenCV 3.0.0中包含非自由模块

本文介绍了在OpenCV 3.0.0中包含非自由模块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

#include <opencv2\features2d\features2d.hpp>

using namespace cv;
using namespace cv::xfeatures2d;
using namespace std;

int main(int argc, char *argv[])
{
    Ptr<SURF> surf = SURF::create();

    return 0;
}

以下代码给出错误:

/home/shivam/1.cpp:2:45: fatal error: opencv2\features2d\features2d.hpp: No such file or directory
 #include <opencv2\features2d\features2d.hpp>

但是头文件包含在include \ opencv2 \ features2d \ features2d.hpp中.看一下这个截图:这是我的1.cpp的cmake文件

But the header file is included in include\opencv2\features2d\features2d.hpp.Have a look at this screenshot:Here is my cmake file for 1.cpp

cmake_minimum_required(VERSION 2.8)
project( 1 )
find_package( OpenCV REQUIRED )
add_executable( 1 1.cpp )
target_link_libraries( 1 ${OpenCV_LIBS} )

推荐答案

在OpenCV 3.0.0中，nonfree模块位于xfeatures2d中，而不位于features2d中.

In OpenCV 3.0.0 nonfree module is in xfeatures2d, not features2d.

此代码将编译:

#include <opencv2\opencv.hpp>
#include <opencv2\xfeatures2d.hpp>

using namespace cv;
using namespace cv::xfeatures2d;

int main(int argc, char *argv[])
{
    Ptr<SURF> surf = SURF::create();
    return 0;
}
