如何从ORB描述符中获取LSH？

Question

我将非常感谢您的意见和答案 我是Opencv的新手

请告诉我，如何从匹配器中获取哈希列表？

我的代码和有趣的行：

//匹配_-＆GT; getListOfLsh（）;

//获取哈希列表“qgdlfospahs ....

int main(int argc, char** argv)

{
cv::Mat img1 = cv::imread("categories2.jpg", CV_LOAD_IMAGE_GRAYSCALE);//CV_LOAD_IMAGE_GRAYSCALE

cv::Ptr<cv::FeatureDetector> detector = ORB::create();
cv::Ptr<cv::DescriptorExtractor> descriptor = ORB::create();

std::vector<cv::KeyPoint> keypoints1;
detector->detect(img1, keypoints1);
std::cout«"find "«keypoints1.size()«" keypoints in img1"«std::endl;

cv::Mat descriptors1;
descriptor->compute(img1, keypoints1, descriptors1);

cv::Ptr<cv::DescriptorMatcher> matcher_;
matcher_ = new cv::FlannBasedMatcher(new cv::flann::LshIndexParams(5, 24, 2));

matcher_->add(descriptors1); // i think that here matcher generate hash indexes

//matcher_->getListOfLsh(); i need something like this 
//Get list of hashes "qgdlfospahsy24sa6nhss65s7hns7" for ORB descriptors?
