#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。 看看这个截图: 这是我的1.cpp
的cmake文件cmake_minimum_required(VERSION 2.8)
project( 1 )
find_package( OpenCV REQUIRED )
add_executable( 1 1.cpp )
target_link_libraries( 1 ${OpenCV_LIBS} )
答案 0 :(得分:3)
在OpenCV 3.0.0中,nonfree
模块位于xfeatures2d
,而不是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;
}
