私のコードはうまく機能していますが、キーポイントを抽出すると、2 つの画像がうまく一致しません。ここで私のコードを見つけることができますが、適切な一致を描画する方法がわかりませんJAVA Android
descriptors = new Mat();
keypoints = new MatOfKeyPoint();
detector = FeatureDetector.create(FeatureDetector.ORB);
detector.detect(img1, keypoints);
descriptor = DescriptorExtractor.create(DescriptorExtractor.ORB);
descriptor.compute(img1, keypoints, descriptors);
matcher = DescriptorMatcher.create(DescriptorMatcher.BRUTEFORCE_HAMMING);
ColorDetection.cvt_YUVtoRGBtoHSV(mYuv,mGraySubmat);
MatOfKeyPoint mKeyPoints = new MatOfKeyPoint();
MatOfDMatch matches = new MatOfDMatch();
detector.detect(mGraySubmat, mKeyPoints);
descriptor.compute(mGraySubmat, mKeyPoints, mIntermediateMat);
matcher.match(mIntermediateMat,descriptors,matches);
mIntermediateMat2.create(resultSize, CvType.CV_8UC1);
Features2d.drawMatches(img1, keypoints, mGraySubmat, mKeyPoints, matches,
mIntermediateMat2,GREEN, RED, MATCH_MASK, Features2d.NOT_DRAW_SINGLE_POINTS);
Imgproc.resize(mIntermediateMat2, mIntermediateMat2, mRgba.size());
Imgproc.cvtColor(mIntermediateMat2, mRgba, Imgproc.COLOR_RGBA2BGRA, 4);
Utils.matToBitmap(mRgba, bmp);
DMatch dm[] = matches.toArray();
List<Point> lp1 = new ArrayList<Point>(dm.length);
List<Point> lp2 = new ArrayList<Point>(dm.length);
KeyPoint tkp[] = keypoints.toArray();
KeyPoint qkp[] = mKeyPoints.toArray();
for (int i = 0; i < dm.length; i++) {
DMatch dma = dm[i];
lp1.add(tkp[dma.trainIdx].pt);
lp2.add(qkp[dma.queryIdx].pt);
}
MatOfPoint2f pointsPrev = new MatOfPoint2f(lp1.toArray(new Point[0]));
MatOfPoint2f pointsAct = new MatOfPoint2f(lp2.toArray(new Point[0]));
Log.i("pointsPrev", pointsPrev.size().toString());
Log.i("pointsAct", pointsAct.size().toString());
fundamental_matrix.create(resultSize, CvType.CV_8UC1);
fundamental_matrix = Calib3d.findFundamentalMat(
pointsAct, pointsPrev, Calib3d.FM_RANSAC, 3, 0.99);
なにか提案を?

マッチをリストに変換できません! がFeature2d.drawMatches()
必要であり、MatOfDmatch
ではないためList<Dmatch>
MatOfDMatch matches, matches12, matches21;
matcher.match( descriptors1, descriptors2, matches12 );
matcher.match( descriptors2, descriptors1, matches21 );
iterate matches12
DMatch forward = matches12[i];
DMatch backward = matches21[forward.trainIdx];
if( backward.trainIdx == forward.queryIdx )
//add forward to matches
Features2d.drawMatches(img1, keypoints, mGraySubmat, mKeyPoints, matches,mIntermediateMat2);
