OpenCV SURF function is not implemented
可能重复我的错误代码是:
错误LNK2019:函数_main中引用的未解析的外部符号“public:__thiscall cv :: SURF :: SURF(double,int,int,bool,bool)”(?? 0SURF @ cv @@ QAE @ NHH_N0 @ Z)
我不知道如何解决它。
我的代码是:
#include <opencv\cv.h>
#include <opencv\highgui.h>
#include <iostream>
#include <conio.h>
#include <opencv2\nonfree\features2d.hpp>
#include <opencv2\legacy\legacy.hpp>
#include <opencv2\core\core.hpp>
#include <stdio.h>
using namespace cv;
using namespace std;
int main()
{
Mat img_1 = imread("kmu1.jpg", CV_LOAD_IMAGE_GRAYSCALE);
Mat img_2 = imread("all.jpg", CV_LOAD_IMAGE_GRAYSCALE);
if(!img_1.data || !img_2.data)
{
cout << "could not open or find the image" << endl;
return -1;
}
int minHessian = 400;
SURF surf( minHessian );
vector <KeyPoint> keyPoints_1, keyPoints_2;
Mat descriptors_1, descriptors_2;
surf(img_1, Mat(), keyPoints_1, descriptors_1, false);
surf(img_2, Mat(), keyPoints_2, descriptors_2, false);
BFMatcher matcher(NORM_L2, false);
vector<DMatch> matches;
matcher.match(descriptors_1, descriptors_2, matches);
Mat img_matches;
drawMatches(img_1, keyPoints_1, img_2, keyPoints_2, matches, img_matches);
imshow("Matches", img_matches);
waitKey(0);
_getch();
return 0;
}
答案 0 :(得分:8)
如果您处于调试模式并使用OpenCV 2.4.5:
,请尝试添加这些库opencv_nonfree245d.lib
opencv_features2d245d.lib
在项目中 - &gt;属性 - &gt;链接器 - &gt;输入 - &gt;附加依赖。
我在使用功能描述教程时遇到了同样的错误并修复了它。
