我已经开始在 c# 中为带有 WPF 的 kinect 进行开发。
当我从 Kinect for Windows Developer Toolkit 启动示例程序“colorBasics”时,相机工作正常,但几秒钟后就冻结了。
我复制了相关代码(所以只有查看相机的代码),它也发生在我自己的程序中。
有人知道我在做什么错吗?
我没有收到任何错误。
这是代码
namespace Testapp
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
private KinectSensor sensor;
private WriteableBitmap colorBitmap;
private byte[] colorPixels;
public MainWindow()
{
InitializeComponent();
}
private void WindowLoaded(object sender, RoutedEventArgs e)
{
foreach (var potentialSensor in KinectSensor.KinectSensors)
{
if (potentialSensor.Status == KinectStatus.Connected)
{
this.sensor = potentialSensor;
break;
}
}
if (null != this.sensor)
{
// Turn on the color stream to receive color frames
this.sensor.ColorStream.Enable(ColorImageFormat.RgbResolution640x480Fps30);
// Allocate space to put the pixels we'll receive
this.colorPixels = new byte[this.sensor.ColorStream.FramePixelDataLength];
// This is the bitmap we'll display on-screen
this.colorBitmap = new WriteableBitmap(this.sensor.ColorStream.FrameWidth, this.sensor.ColorStream.FrameHeight, 96.0, 96.0, PixelFormats.Bgr32, null);
// Set the image we display to point to the bitmap where we'll put the image data
this.Image.Source = this.colorBitmap;
// Add an event handler to be called whenever there is new color frame data
this.sensor.ColorFrameReady += this.SensorColorFrameReady;
// Start the sensor!
try
{
this.sensor.Start();
}
catch (IOException)
{
this.sensor = null;
}
}
}
private void SensorColorFrameReady(object sender, ColorImageFrameReadyEventArgs e)
{
using (ColorImageFrame colorFrame = e.OpenColorImageFrame())
{
if (colorFrame != null)
{
// Copy the pixel data from the image to a temporary array
colorFrame.CopyPixelDataTo(this.colorPixels);
// Write the pixel data into our bitmap
this.colorBitmap.WritePixels(
new Int32Rect(0, 0, this.colorBitmap.PixelWidth, this.colorBitmap.PixelHeight),
this.colorPixels,
this.colorBitmap.PixelWidth * sizeof(int),
0);
}
}
}
}
}
