C# 为确定的地标点绘制等高线（OpenCvForUnity）

我以前使用过python的OpenCV。但是我越来越难将OpenCV与unity结合使用

I面部特定点的训练数据。我可以找到地标点，我可以在unity webcamTexture上显示这些点，但我想在由我确定的地标点上绘制轮廓。首先，我需要将地标点转换为凸包点，以便在现有点之间绘制轮廓。如何转换？

我试过了

// detect face landmark points.
OpenCVForUnityUtils.SetImage(faceLandmarkDetector, rgbaMat);
for (int i = 0; i < trackedRects.Count; i++)
{
  List<Vector2> points = faceLandmarkDetector.DetectLandmark(rect);
  List<Vector2> pointss = new List<Vector2>();
  //Draw Contours
  List<Point> pointsss = OpenCVForUnityUtils.ConvertVector2ListToPointList(pointss);
  MatOfPoint hullPointMat = new MatOfPoint();
  hullPointMat.fromList(pointsss);
  List<MatOfPoint> hullPoints = new List<MatOfPoint>();
  hullPoints.Add(hullPointMat);
  Imgproc.drawContours(rgbaMat, hullPoints, -1, new Scalar(150, 100, 5,255), -1);
}

//检测面部标志点。
OpenCVForUnityUtils.SetImage（faceLandmarkDetector，rgbaMat）；
for（int i=0；i

Imgproc.drawContours (rgbaMat, hullPoints, -1, new Scalar (0, 255, 0), 2);
