Question

我使用kinect。我的目标是存储值给我一个身体位置（头部，手部等）的kinect。我写了一些代码，但我无法理解应该保存什么值以及如何。我想在db或txt文件中存储头部，手部和脚部的位置。我希望数据能够理解站在kinect前面的人。例如，如果有人移动她的手，kinect将发送一个值。我必须存储它并理解并理解所采取的行动。仅提供少量信息

这是我的代码：

        KinectSensor sensor = KinectSensor.KinectSensors[0];
        byte[] pixelData;
        Skeleton[] skeletons;

        public MainWindow()

我认为您正在寻找的是获得某些关节的X，Y，Z坐标？在这种情况下，请添加以下代码：

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);

如您所见，这仅定义了上半身部分的矢量。只需按照我的方式添加缺失的关节。您需要以下程序集：

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

从kinect骨架轨道保存关节
