OpenCV flann.h断言错误 [英] OpenCV flann.h assertion Error

问题描述

我写了一个程序，得到2张图片之间的匹配。
这是代码。但如果我使用BruteForceMatcher>（不是flann）它工作。

  #include< stdio.h> 
 #includeopencv2 / core / core.hpp
 #includeopencv2 / features2d / features2d.hpp
 #includeopencv2 / highgui / highgui.hpp
 
 using namespace cv; 
 
 void help（）
 {
 printf（\\\
This程序演示使用features2d检测器，描述符提取器和简单matcher \\\

使用SURF描述符：\\\

\\\

用法：\\\
 matcher_simple< image1>< image2> \\\
）; 
} 
 
 int main（）
 {
 
 Mat img1 = imread（C：\\Users\\Hayk\ \Desktop \\source1.bmp，CV_LOAD_IMAGE_GRAYSCALE）; 
 Mat img2 = imread（C：\\Users\\Hayk\\Desktop\\\source2.bmp，CV_LOAD_IMAGE_GRAYSCALE）; 
 if（img1.empty（）|| img2.empty（））
 {
 printf（无法读取其中一个images \\\
 
 return -1; 
} 
 
 //检测keypoints 
 SurfFeatureDetector检测器（6000）; 
 vector< KeyPoint> keypoints1，keypoints2; 
 detector.detect（img1，keypoints1）; 
 detector.detect（img2，keypoints2）; 
 
 //计算描述符
 SurfDescriptorExtractor提取器; 
 Mat descriptors1，descriptors2; 
 extractor.compute（img1，keypoints1，descriptors1）; 
 extractor.compute（img2，keypoints2，descriptors2）; 
 
 //匹配描述符
 FlannBasedMatcher匹配器; 
 vector< DMatch>火柴; 
 matcher.match（descriptors1，descriptors2，matches）; 
 
 //绘制结果
 namedWindow（matches，1）; 
 Mat img_matches; 
 drawMatches（img1，keypoints1，img2，keypoints2，matches，img_matches）; 
 imshow（matches，img_matches）; 
 waitKey（0）; 
 
 return 0; 
} 
  

运行程序后遇到此错误

  OpenCV错误：未知
函数中的assertion failed（dataset.type（）== CvType< T> :: type c：\Users\vp\work\ocv\opencv\modules\features2d\..\flann\include\o 
 pencv2 / flann / flann.hpp，第105行
  

任何人都可以告诉我我做错了什么？

我有几个问题的C ++ OpenCV的Windows界面。当我必须使用Windows，我使用C接口。

I wrote a program which gets matches between 2 pictures. And this is the code. but if I use BruteForceMatcher> (not flann) it works.

#include <stdio.h>
#include "opencv2/core/core.hpp"
#include "opencv2/features2d/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"

using namespace cv;

void help()
{
    printf("\nThis program demonstrates using features2d detector, descriptor extractor and simple matcher\n"
    "Using the SURF desriptor:\n"
    "\n"
    "Usage:\n matcher_simple <image1> <image2>\n");
}

int main()
{

    Mat img1 = imread("C:\\Users\\Hayk\\Desktop\\source1.bmp", CV_LOAD_IMAGE_GRAYSCALE);
    Mat img2 = imread("C:\\Users\\Hayk\\Desktop\\source2.bmp", CV_LOAD_IMAGE_GRAYSCALE);
    if(img1.empty() || img2.empty())
    {
        printf("Can't read one of the images\n");
        return -1;
    }

    // detecting keypoints
    SurfFeatureDetector detector(6000);
    vector<KeyPoint> keypoints1, keypoints2;
    detector.detect(img1, keypoints1);
    detector.detect(img2, keypoints2);

    // computing descriptors
    SurfDescriptorExtractor extractor;
    Mat descriptors1, descriptors2;
    extractor.compute(img1, keypoints1, descriptors1);
    extractor.compute(img2, keypoints2, descriptors2);

    // matching descriptors
    FlannBasedMatcher matcher;
    vector<DMatch> matches;
    matcher.match(descriptors1, descriptors2, matches);

    // drawing the results
    namedWindow("matches", 1);
    Mat img_matches;
    drawMatches(img1, keypoints1, img2, keypoints2, matches, img_matches);
    imshow("matches", img_matches);
    waitKey(0);

    return 0;
} 

And this error I am getting after running the program

OpenCV Error: Assertion failed (dataset.type() == CvType<T>::type()) in unknown
function, file c:\Users\vp\work\ocv\opencv\modules\features2d\..\flann\include\o
pencv2/flann/flann.hpp, line 105

Can anyone say to me what I am doing wrong?

解决方案

Your code works just fine on Linux with OpenCV 2.3.1a.

I've had several problems with the C++ OpenCV's interface for Windows. When I have to use Windows, I use the C interface.
