從kinect骨架軌跡保存的關節

Question

我使用的是kinect。我的目標是存儲這些值給我身體位置（頭部，手部等）的動力。我寫了一些代碼，但我不明白應該保存什麼值，以及如何存儲。我想要在db或txt文件中存儲頭，手和腳的位置。我希望數據能夠理解例如，如果有人移動她的手，kinect會發送一個值。我必須將其存儲並理解並理解所採取的行動。請輸入以下信息：

這是我的代碼：

我想你要找的是爲某些接頭獲得X，Y，Z座標嗎？ 在這種情況下，添加以下代碼：

Vector3D ShoulderCenter = new Vector3D(skeleton.Joints[JointType.ShoulderCenter].Position.X, skeleton.Joints[JointType.ShoulderCenter].Position.Y, skeleton.Joints[JointType.ShoulderCenter].Position.Z); 
      Vector3D RightShoulder = new Vector3D(skeleton.Joints[JointType.ShoulderRight].Position.X, skeleton.Joints[JointType.ShoulderRight].Position.Y, skeleton.Joints[JointType.ShoulderRight].Position.Z); 
      Vector3D LeftShoulder = new Vector3D(skeleton.Joints[JointType.ShoulderLeft].Position.X, skeleton.Joints[JointType.ShoulderLeft].Position.Y, skeleton.Joints[JointType.ShoulderLeft].Position.Z); 
      Vector3D RightElbow = new Vector3D(skeleton.Joints[JointType.ElbowRight].Position.X, skeleton.Joints[JointType.ElbowRight].Position.Y, skeleton.Joints[JointType.ElbowRight].Position.Z); 
      Vector3D LeftElbow = new Vector3D(skeleton.Joints[JointType.ElbowLeft].Position.X, skeleton.Joints[JointType.ElbowLeft].Position.Y, skeleton.Joints[JointType.ElbowLeft].Position.Z); 
      Vector3D RightWrist = new Vector3D(skeleton.Joints[JointType.WristRight].Position.X, skeleton.Joints[JointType.WristRight].Position.Y, skeleton.Joints[JointType.WristRight].Position.Z); 
      Vector3D LeftWrist = new Vector3D(skeleton.Joints[JointType.WristLeft].Position.X, skeleton.Joints[JointType.WristLeft].Position.Y, skeleton.Joints[JointType.WristLeft].Position.Z); 

此只定義了向量的上身部分，你可以看到。按照我所做的方式添加缺失的關節。 您需要以下組件：

using System.Windows.Media; 
using Microsoft.Kinect.Toolkit.Fusion; 
using System.Windows.Media.Media3D;
