Unhandled exception in OpenCV feature matching - c++

Question

I'm now working on feature matching, and I wrote these codes below.
void CLPS::ExtractKeyPoints()
{
vector<DMatch> init_matches;
ULONGLONG timer;
timer = GetTickCount64();
Ptr<BRISK> fd_a = BRISK::create(20);
fd_a->detectAndCompute(S, Mat(), spoints, desc_s, false);
fd_a->detectAndCompute(T, Mat(), tpoints, desc_t, false);
timer = GetTickCount64() - timer;
cout << "Detect and compute: " << timer << " milliseconds complete. Output: " << spoints.size() << " points. \n";
timer = GetTickCount64();
FlannBasedMatcher matcher = FlannBasedMatcher(cv::makePtr<cv::flann::LshIndexParams>(10, 32, 2));
matcher.match(desc_s, desc_t, init_matches);
timer = GetTickCount64() - timer;
cout << "Matching time: " << timer << " milliseconds complete. " << endl;
Point2f spt, tpt;
int num_matches = 0;
vector<DMatch>::iterator iter_matches;
coord_matches.create(1, 3, CV_32FC1);
Mat cm_row;
cm_row.create(1, 3, CV_32FC1);
if (!init_matches.empty())
{
for (iter_matches = init_matches.begin(); iter_matches != init_matches.end(); ++iter_matches)
{
spt = spoints[iter_matches->queryIdx].pt;
tpt = tpoints[iter_matches->trainIdx].pt;
if (std::abs(spt.y - tpt.y) < VERTICAL_EPSILON && tpt.x - spt.x < upperbound && tpt.x - spt.x > lowerbound)
{
num_matches++;
coord_matches.reserve(num_matches);
cm_row.at<float>(0, 0) = spt.x;// 与 CV_32FC1 对应
cm_row.at<float>(0, 1) = spt.y;
cm_row.at<float>(0, 2) = tpt.x - spt.x;
coord_matches.push_back(cm_row);
}
}
cout << coord_matches.rows << " matches found." << endl;
}
else
{
cerr << "No match is found. Validate your source data or report to us if there is a bug. " << endl;
}
}
Then I just call it like this:
CLPS lps;
lps.ExtractKeyPoints();
However, it triggers an exception with following message when this function is returning:
Unhandled exception at 0x00007FFC0797D328 (ucrtbase.dll) in dars_lps.exe: An invalid parameter was passed to a function that considers invalid parameters fatal.
where dars_lps.exe is my application name. Then the program jumps to some destructors in <vector>.
I'm using Visual Studio 2015 on Windows 8.1 Update 1, and my OpenCV version is 3.1. I have confirmed that I'm linking to correct version of library files (i.e. vc14).
I was once working on Visual Studio 2010 on Windows 7 SP1, OpenCV 2.4.9, but it never reported such an exception.
I know this question may be similar to some other questions elsewhere (e.g. this on OpenCV site), occuring when calling different functions, but all of them are staying unsolved. I suspect that the problem lies in BRISK or FlannBasedMatcher, but I can't comment out those code (or this function will be virtually empty, and obviously, no more exceptions).
I also noticed that the problem was rising up after OpenCV 3.0 was released, and most of the similar problems happen in newer versions of Visual Studio or Windows. Both 64-bit and 32-bit platforms have this kind of problems. There does exist a report of such problem in Visual Studio 2015 here, but it was OpenCV 3.0 that is used, when there were no library built for Visual Studio 2015 yet.
Is it still a bug to be fixed or an error of syntax by myself?
