在android opencv中使用findFundamentalMat時出現錯誤，但無法解析它

我捕獲連續圖像並提取快速特徵，並進一步匹配這些特徵以獲取Rotational和平移矩陣。這將幫助我進行3D場景重建，但在使用Calib3d.findFundamentalMat命令時出現錯誤，但無法解決此問題。在android opencv中使用findFundamentalMat時出現錯誤，但無法解析它

  MatOfDMatch matches = new MatOfDMatch(); 
      descriptorM.match(firstImgDescriptors, secondImgDescriptors, matches); 

      Calib3d calib = new Calib3d(); 
      MatOfPoint2f imgpts1 = getMatOfPoint2fFromDMatches(matches, keyPoints1, 0); 
      MatOfPoint2f imgpts2 = getMatOfPoint2fFromDMatches(matches, keyPoints2, 1); 
      Mat F = Calib3d.findFundamentalMat(imgpts1, imgpts2, Calib3d.FM_RANSAC,3, 0.99); 


    private static MatOfPoint2f getMatOfPoint2fFromDMatches(MatOfDMatch matches, 
                 MatOfKeyPoint keyP, int tipo) { 
      /* 0 para query, 1 para train*/ 
      DMatch dm[] = matches.toArray(); 
      List<Point> lp = new ArrayList<Point>(dm.length); 
      KeyPoint tkp[] = keyP.toArray(); 
      if(tipo == 0){ 
       for (int i = 0; i < dm.length; i++) { 
        DMatch dmm = dm[i]; 
        //if (dmm.queryIdx < tkp.length) 
         lp.add(tkp[dmm.queryIdx].pt); 
       } 
      } 
      if (tipo == 1) { 
       for (int i = 0; i < dm.length; i++) { 
        DMatch dmm = dm[i]; 
        // if (dmm.trainIdx < tkp.length) 
         lp.add(tkp[dmm.trainIdx].pt); 
       } 
      } 

      return new MatOfPoint2f(lp.toArray(new Point[0])); 
     }

由於問題解決之前打印這些尺寸。這是由於空值 –

錯誤是告訴你，你的imgpoints1和/或imgpoints2不正確的2D或3D點矩陣。

嘗試直接調用Calib3d.findFundamentalMat(...)
