Question

我有一个程序可以检查Kinect是否已连接到计算机。但是，我真的不知道我是否需要调用一个方法（我会这样认为）以及在哪里？我附上了我从Kinect入门书中获得的代码。谢谢！

using System;
using System.Windows;
using System.Windows.Controls;
using Microsoft.Kinect;

namespace test
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

        }

    KinectSensor kinectSensor;
    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        try
        {
            KinectSensor.KinectSensors.StatusChanged += Kinects_StatusChanged;
            foreach (KinectSensor kinect in KinectSensor.KinectSensors)
            {
                if (kinect.Status == KinectStatus.Connected)
                {
                    kinectSensor = kinect;
                    MessageBox.Show("Connected");
                    break;
                }
            }
            if (KinectSensor.KinectSensors.Count == 0)
                MessageBox.Show("No Kinect Found");
            else
                Initialize();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

    void Kinects_StatusChanged(object sender, StatusChangedEventArgs e)
    {
        switch (e.Status)
        {
            case KinectStatus.Connected:
                if (kinectSensor == null)
                {
                    kinectSensor = e.Sensor;
                    Initialize();
                }
                break;
            case KinectStatus.Disconnected:
                if (kinectSensor == e.Sensor)
                {
                    Clean();
                    MessageBox.Show("Kinect was disconnected");
                }
                break;
            case KinectStatus.NotReady:
                break;
            case KinectStatus.NotPowered:
                if (kinectSensor == e.Sensor)
                {
                    Clean();
                    MessageBox.Show("Kinect is not powered anymore.");
                }
                break;
            default:
                MessageBox.Show("Unhandled Status: " + e.Status);
                break;
        }
    }

    private void Initialize()
    {
        if (kinectSensor == null)
            return;
        kinectSensor.Start();
    }

    private void Clean()
    {
        if (kinectSensor != null)
        {
            kinectSensor.Stop();
            kinectSensor = null;
        }
    }

}

}

下载Kinect for Windows Developer Toolkit。有很多关于如何做多件事的例子，这些例子可以让你开始并帮助你理解如何与Kinect交谈。

一旦连接到Kinect，您需要进行设置，然后订阅事件回调。你最终会得到一个看起来像这样的函数：

private void InitializeKinectServices(KinectSensorManager kinectSensorManager, KinectSensor sensor)
{
    // configure the color stream
    kinectSensorManager.ColorFormat = ColorImageFormat.RgbResolution640x480Fps30;
    kinectSensorManager.ColorStreamEnabled = true;

    // configure the depth stream
    kinectSensorManager.DepthStreamEnabled = true;

    kinectSensorManager.TransformSmoothParameters =
        new TransformSmoothParameters
        {
            // as the smoothing value is increased responsiveness to the raw data
            // decreases; therefore, increased smoothing leads to increased latency.
            Smoothing = 0.5f,
            // higher value corrects toward the raw data more quickly,
            // a lower value corrects more slowly and appears smoother.
            Correction = 0.5f,
            // number of frames to predict into the future.
            Prediction = 0.5f,
            // determines how aggressively to remove jitter from the raw data.
            JitterRadius = 0.05f,
            // maximum radius (in meters) that filtered positions can deviate from raw data.
            MaxDeviationRadius = 0.04f
        };

    // configure the skeleton stream
    sensor.SkeletonFrameReady += OnSkeletonFrameReady;
    kinectSensorManager.SkeletonStreamEnabled = true;

    // initialize the gesture recognizer
    _gestureController = new GestureController();
    _gestureController.GestureRecognized += OnGestureRecognized;

    kinectSensorManager.KinectSensorEnabled = true;

    if (!kinectSensorManager.KinectSensorAppConflict)
    {
      // additional init
    }
}

这是我的通用设置功能，它基于Developer Toolkit中的示例。您将无法将其插入代码中，它将起作用。查看工具包中的示例将使您了解这种情况发生的位置以及如何最好地管理它。

KinectExplorer示例是一个很好的整体项目。它还可以让您清楚地了解上述功能的工作原理（它具有相同的功能）。

如何在Kinect SDK中调用方法？
