我想在Visual Studio 2013中使用opencv 3.0提取图像的功能。
我的代码:
#include <stdio.h>
#include <iostream>
#include "opencv2\core.hpp"
#include "opencv2\features2d.hpp"
#include <opencv2\xfeatures2d.hpp>
#include <opencv2\highgui.hpp>
using namespace cv;
using namespace cv::xfeatures2d;
void readme();
/** @function main */
int main(int argc, char** argv)
{
if (argc != 3)
{
readme(); return -1;
}
Mat img_1 = imread(argv[1], IMREAD_GRAYSCALE);
Mat img_2 = imread(argv[2], IMREAD_GRAYSCALE);
if (!img_1.data || !img_2.data)
{
std::cout << " --(!) Error reading images " << std::endl; return -1;
}
//-- Step 1: Detect the keypoints using SURF Detector
int minHessian = 400;
Ptr<SURF> detector = SURF::create(minHessian);
std::vector<KeyPoint> keypoints_1, keypoints_2;
detector->detect(img_1, keypoints_1);
detector->detect(img_2, keypoints_2);
//-- Draw keypoints
Mat img_keypoints_1; Mat img_keypoints_2;
drawKeypoints(img_1, keypoints_1, img_keypoints_1, Scalar::all(-1), DrawMatchesFlags::DEFAULT);
drawKeypoints(img_2, keypoints_2, img_keypoints_2, Scalar::all(-1), DrawMatchesFlags::DEFAULT);
//-- Show detected (drawn) keypoints
imshow("Keypoints 1", img_keypoints_1);
imshow("Keypoints 2", img_keypoints_2);
waitKey(0);
return 0;
}
/** @function readme */
void readme()
{
std::cout << " Usage: ./SURF_detector <img1> <img2>" << std::endl;
}
错误:
Cannot open include file: 'opencv2\xfeatures2d.hpp': No such file or directory
在C:\ OpenCV3.0.0 \ opencv \ build \ include \ opencv2
目录,没有xfeatures2d.hpp文件。因此,我应该从外部导入这个库。如何解决?
