10.特征匹配

特征匹配器
BFMatcher matcher = BFMatcher.create(NORM_L2, false);
MatOfKeyPoint keyPoints2 = new MatOfKeyPoint();
featureDetector.detectAndCompute(img2, new MatOfRect(), keyPoints2, descriptors2);
List<DMatch> mlist = new ArrayList<>();*/
匹配特征
Mat matches = matcher.match(keyPoints1, descriptors2, mlist);
绘制匹配点
Mat imgOut = new Mat();
Imgproc.drawMatches(imgOut, keypoints1, keypoints2, matches, new Scalar(0, 0, 255));
