将x和y Kinect坐标映射到像素坐标

Question

我正在使用Kinect定位应用程序，我想在Android应用程序中显示它。我得到的深度值以米为单位，并且它的值为负值，因为坐标零位于Kinect的中心。我仍然困惑如何使像素坐标和计算成为真实值。有人可以给我建议，还是可以在Android中显示建议？这是代码的一部分：

 if (dataReceived)
                {
                    foreach (Body body in _bodies)
                    {
                        if (body.IsTracked)
                        {
                            IReadOnlyDictionary<JointType, Joint> joints = body.Joints;
                            Dictionary<JointType, Point> jointPoints = new Dictionary<JointType, Point>();


                            foreach (JointType jointType in joints.Keys)
                            {
                                // sometimes the depth(Z) of an inferred joint may show as negative
                                // clamp down to 0.1f to prevent coordinatemapper from returning (-Infinity, -Infinity)
                                CameraSpacePoint position = joints[jointType].Position;
                                if (position.Z < 0)
                                {
                                    position.Z = InferredZPositionClamp;
                                }

                                DepthSpacePoint depthSpacePoint = this.coordinateMapper.MapCameraPointToDepthSpace(position);
                                jointPoints[jointType] = new Point(depthSpacePoint.X, depthSpacePoint.Y);
                            }

                            Joint Head = joints[JointType.Head];

                            float x = Head.Position.X;
                            float y = Head.Position.Z;

因为我想使其成为二维空间，所以我将z用作y，因为我认为y坐标并不重要。我的下一个问题是y Kinect坐标对二维空间有影响吗？
