Kinect虚拟试衣间开发(3)-拍照和声控功能

拍照

编写成一个函数，方便后面调用

private void takephoto()
{
if (this.bitmap != null)
{
// Create a render target to which we'll render our composite image
RenderTargetBitmap renderBitmap = new RenderTargetBitmap((int)all.ActualWidth, (int)all.ActualHeight, 96.0, 96.0, PixelFormats.Pbgra32);

DrawingVisual dv = new DrawingVisual();
using (DrawingContext dc = dv.RenderOpen())
{
VisualBrush brush = new VisualBrush(all);
dc.DrawRectangle(brush, null, new Rect(new Point(), new Size(all.ActualWidth, all.ActualHeight)));
}

renderBitmap.Render(dv);
// create a png bitmap encoder which knows how to save a .png file
BitmapEncoder encoder = new PngBitmapEncoder();

// create frame from the writable bitmap and add to encoder
encoder.Frames.Add(BitmapFrame.Create(renderBitmap));

string time = DateTime.Now.ToString("hh'-'mm'-'ss", CultureInfo.CurrentUICulture.DateTimeFormat);

string myPhotos = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures);

string path = System.IO.Path.Combine(myPhotos, "KinectScreenshot-Color-" + time + ".png");

// write the new file to disk
try
{
// FileStream is IDisposable
using (FileStream fs = new FileStream(path, FileMode.Create))
{
encoder.Save(fs);
}
status.Content = "照片已保存到" + path;
//MessageBox.Show("照片已保存到" + path);
}
catch (IOException)
{
status.Content = "照片保存失败";
//MessageBox.Show("照片保存失败");
}
}
}

声控

先要下载相应的Speech SDK和 语言包，查看 Kinect Browser 里面Component 要下载的部分。

代码参考 Kinect Browser 里面 Sample C#地最后一个，Speech Basics-WPF
