一個C++凸性缺陷包裝（OpenCV）？

我正在嘗試爲OpenCV創建一個C++包裝器，但不幸的是無法使其工作。我一直得到同樣的錯誤：「OpenCV錯誤：錯誤的參數（凸包既不是序列也不是矩陣）」。我不明白爲什麼。一個C++凸性缺陷包裝（OpenCV）？

下面的代碼：

void convexityDefects (vector <vector<Point> > contour, vector <vector<int> > convexHullPoints, vector <vector<Point> > *convexHullDefects) 
    { 
     CvSeq *contourSeq; 
     CvSeq *convexHullDefectsSeq; 
     CvSeq *convexHullSeq; 

     CvMemStorage *contourSeqStorage = cvCreateMemStorage (0); 
     CvMemStorage *convexHullSeqStorage = cvCreateMemStorage (0); 
     CvMemStorage *convexHullDefectsSeqStorage = cvCreateMemStorage (0); 
     CvMemStorage *cvConvexityDefectsStorage = cvCreateMemStorage (0); 

     contourSeq = cvCreateSeq (CV_SEQ_KIND_GENERIC | CV_32SC2, sizeof (CvSeq), sizeof (CvPoint), contourSeqStorage); 
     convexHullDefectsSeq = cvCreateSeq (CV_SEQ_KIND_GENERIC, sizeof (CvSeq), sizeof (CvPoint), convexHullDefectsSeqStorage); 
     convexHullSeq = cvCreateSeq (CV_SEQ_KIND_GENERIC, sizeof (CvSeq), sizeof (int), convexHullSeqStorage); 

     for (int counter = 0; counter < contour.at (0).size(); counter ++) 
     { 
      CvPoint element = {contour.at (0).at (counter).x, contour.at (0).at (counter).y}; 
      cvSeqPush (contourSeq, &element); 
     } 

     int hullArray [convexHullPoints.at (0).size()]; 

     for (int counter = 0; counter < convexHullPoints.size(); counter ++) 
     { 
      hullArray [counter] = convexHullPoints.at (0).at (counter); 
     } 

     for (int counter = 0; counter < convexHullPoints.size(); counter ++) 
     { 
      cvSeqPush (convexHullSeq, &(hullArray [counter])); 
     } 

     convexHullDefectsSeq = cvConvexityDefects (contourSeq, &convexHullSeq, cvConvexityDefectsStorage); 

     CvConvexityDefect convexHullDefectsArray [convexHullDefectsSeq -> total]; 

     cvCvtSeqToArray (convexHullDefectsSeq, &convexHullDefectsArray, CV_WHOLE_SEQ); 

     for (int counter = 0; counter < convexHullDefectsSeq -> total; counter ++) 
     { 
      CvPoint start = {convexHullDefectsArray [counter].start -> x, convexHullDefectsArray [counter].start -> y}; 
      CvPoint depthPoint = {convexHullDefectsArray [counter].depth_point -> x, convexHullDefectsArray [counter].depth_point -> y}; 
      CvPoint end = {convexHullDefectsArray [counter].end -> x, convexHullDefectsArray [counter].end -> y}; 

      vector <Point> convexityDefectVector; 
      convexityDefectVector.push_back (start); 
      convexityDefectVector.push_back (depthPoint); 
      convexityDefectVector.push_back (end); 

      convexHullDefects -> push_back (convexityDefectVector); 
     } 

     cvReleaseMemStorage (&contourSeqStorage); 
     cvReleaseMemStorage (&convexHullSeqStorage); 
     cvReleaseMemStorage (&convexHullDefectsSeqStorage); 
     cvReleaseMemStorage (&cvConvexityDefectsStorage); 
    }

請參閱工作源代碼：http://stackoverflow.com/a/35190031/763355 – MoDJ

你應該看看其他this崗位上SO。看來他已經解決了這個問題。

謝謝。我已經檢查過這個帖子，但是我不能使用他的包裝，因爲他在程序中使用了CvMat而不是CvSeq來表示凸包。由於幾個原因，我無法提及CvMat。你真的看到我的代碼有什麼問題嗎？ – fdh
