Question

您好，我正在使用Kinect进行的项目。不幸的是，代码是测试版，我需要将其更新为1.5 sdk版本。我尝试了一些东西，但他们不会工作。这是我到目前为止所拥有的。该方法称为nui_DepthFrameReady。

 void nui_DepthFrameReady(object sender, ImageFrameReadyEventArgs e)
    {
        if (!savedDepth)
        {
            PlanarImage Image = e.ImageFrame.Image;
            byte[] convertedDepthFrame = convertDepthFrame(Image.Bits);

            depth.Source = BitmapSource.Create(
                Image.Width, Image.Height, 96, 96, PixelFormats.Bgr32, null, convertedDepthFrame, Image.Width * 4);

            ++totalFrames;

            DateTime cur = DateTime.Now;
            if (cur.Subtract(lastTime) > TimeSpan.FromSeconds(1))
            {
                int frameDiff = totalFrames - lastFrames;
                lastFrames = totalFrames;
                lastTime = cur;
                frameRate.Text = frameDiff.ToString() + " fps";
            }

            if (subscribed)
            {
                //byte[] ColoredBytes = GenerateColoredBytes(e.ImageFrame);
                //create an image based on the colored bytes
                BitmapSource myBitmapDepth = BitmapSource.Create(Image.Width, Image.Height, 96, 96, PixelFormats.Bgr32, null, convertedDepthFrame, Image.Width * PixelFormats.Bgr32.BitsPerPixel / 8);
                string imageFilePath = @"C:\Temp\kinect\depth\bmpDepthFrame_" + cur.TimeOfDay.ToString().Replace(':', '.') + ".png";
                string dataFilePath = @"C:\Temp\kinect\depth\depthFrame_" + cur.TimeOfDay.ToString().Replace(':', '.') + ".dat";
                //savePngFrame(myBitmapDepth, imageFilePath);

                //Crop frame to size 180x240
                byte[] croppedDepthFrame = new byte[180 * 240 * 2];

                for (int i = 0; i < 240; i++)
                {
                    for (int j = 0; j < 180 * 2; j += 2)
                    {
                        croppedDepthFrame[i * 180 * 2 + j] = Image.Bits[i * 320 * 2 + j + 69 * 2];
                        croppedDepthFrame[i * 180 * 2 + j + 1] = Image.Bits[i * 320 * 2 + j + 1 + 69 * 2];
                        //Console.Write((i * 180 * 2 + j) + "-" + (i * 180 * 2 + j + 69*2) +", ");
                    }
                    //Console.WriteLine();
                }
                FileStream fs = new FileStream(dataFilePath, FileMode.Create);
                fs.Write(croppedDepthFrame, 0, croppedDepthFrame.Length);
                fs.Close();
            }

            savedDepth = true;
        }
    }

感谢您的帮助。这就是我到目前为止所拥有的

    }

Image.Bits在kinect或Image.Width，Image.Height的新SDK中没有定义这些是正在发生的错误，所以我不知道如何转换代码以获得相同的信息。

我正在将您的样本与Kinect 1.5 SDK示例中的示例进行比较，看起来您所谓的Image可能与pixelData相同。我没有看到Image定义在哪里，所以我猜。这有帮助吗？

将Kinect Beta代码转换为1.5版
