我正在尝试将 kinect 深度传感器图像保存到 png 文件中。我试图用我的 RGB 相机拍摄它，它没有任何问题。有什么我错过的吗？PS 我正在使用 Kinect ToolKit 的函数来显示 rgb 和深度图像。

WriteableBitmap depthBitmap;
DepthStreamManager dsm;
dsm = new DepthStreamManager();
kinect.DepthStream.Enable(DepthImageFormat.Resolution640x480Fps30);
kinect.DepthFrameReady += kinect_DepthFrameReady;
depthBitmap = new WriteableBitmap(kinect.DepthStream.FrameWidth,this.kinect.DepthStream.FrameHeight, 96.0, 96.0, PixelFormats.Gray16, null);
private string TakeImage(int x)
    {
        if (x == 0)
        {
            BitmapEncoder encoder = new PngBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(this.depthBitmap));
            string myPhotos = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
            string path = System.IO.Path.Combine(myPhotos, "Image 1.png");
            try
            {
                using (FileStream fs = new FileStream(path, FileMode.Create))
                {
                    encoder.Save(fs);
                }


            }
            catch (IOException details)
            {
                Console.Write(details.ToString());

            }
            if (path == null)
                return "Image was not taken.";
            else
                return path;
        }}

If you use the Coding4Fun Kinect toolkit, I believe you can use ImageFrame objects. You can convert an ImageFrame object to Bitmap and from there you should be able to save it as a PNG with no problems.

Bit of a long-winded route to the solution but I'm not currently using the machine which has my Kinect stuff on it.

Edit: If you're using WinForms, you can simply use the Coding4Fun toolkit method ImageFrame.ToBitmap() and then save as PNG from there.

The code should look something like this:

private void saveAsPNG(ImageFrame myImageFrame, string path)
{
   Bitmap bmp = myImageFrame.ToBitmap();

   bmp.Save(path, System.Drawing.Imaging.ImageFormat.Png);

   bmp.Dispose();
}

解决我自己的问题：

使用 Kinect 的 ToolKit，他们实际上提供了一个可写位图函数，允许我抓取 ColorStreamManager 或 DepthStreamManager 的 WritableBitmap。我之前的错误是因为我没有使用 Kinect 的先天显示方法，所以 writeablebitmap 肯定是空的。这是我的固定代码。

WriteableBitmap wmp;
            wmp = cis.Bitmap;
            BitmapEncoder encoder = new PngBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(wmp));
            string path = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop),"Image 1.png");
            try
            {
                using (FileStream fs = new FileStream(path, FileMode.Create))
                {
                    encoder.Save(fs);
                }
            }
            catch (IOException ioe)
            {
                Console.WriteLine(ioe.ToString());
            }
            return path;

你甚至不需要WriteableBitmap。只是带有保存pixeldata的BitmapSource的编码器。

using Microsoft.Kinect;
using System.Windows.Media; // WindowsBase
using System.Windows.Media.Imaging; //PresentationCore

...

static void sensor_DepthFrameReady(object sender, DepthImageFrameReadyEventArgs e)
    {

        DepthImageFrame DIF = e.OpenDepthImageFrame();
        if (DIF == null){return;}            

        short[] pixels = new short[DIF.PixelDataLength];
        DIF.CopyPixelDataTo(pixels);

        if (check == 0)
        {
            int stride = DIF.Width * DIF.BytesPerPixel;
            BitmapEncoder encoder = new PngBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(BitmapSource.Create(
                DIF.Width, DIF.Height, 96, 96, PixelFormats.Gray16, null, pixels, stride)));

            string path = System.IO.Path.Combine(
                Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "kimage.png");

            try
            {
                using (FileStream fs = new FileStream(path, FileMode.Create))
                {
                    encoder.Save(fs);
                }
            }
            catch (IOException ioe)
            {
                Console.WriteLine(ioe.ToString());
            }
            check = 1;
        }}

环境：

  • Visual Studio 2012 速成版
  • Microsoft.Kinect 库 1.7.0.0
  • 编码器需要组装 System.Xaml
