プログラムを実行すると、常にこのエラーが発生します...
私のプログラムの何が問題なのかわかりませんが、参考までに、実際に私のプログラムは次のような多くの画像処理アルゴリズムで構成されています
- viola-jones、手の検出のための haarcascade
- ハンド トラッキング用のカムシフト + カルマン フィルター
- 指を数えるための凸包および凸性欠陥
- およびその他の前処理 ....
これらのプロセスがエラーを引き起こしているかどうかはわかりません...
しかし、凸包/凸性の欠陥を取り除くと、エラーはなくなりました...解決策はありますか?

原点 DrawandComputeFingersNUm() を見ると、行が表示されます
