有没有人知道,如果可能的话,如何降低kinect帧的颜色流分辨率?因为全高清大小对我的scope.Thanks来说太高了,所以我找到了全高清帧的代码:
private BitmapSource ToBitmap(ColorFrame frame)
{
int width = frame.FrameDescription.Width;
int height = frame.FrameDescription.Height;
PixelFormat format = PixelFormats.Bgr32;
byte[] pixels = new byte[width * height * ((PixelFormats.Bgr32.BitsPerPixel + 7) / 8)];
if (frame.RawColorImageFormat == ColorImageFormat.Bgra)
{
frame.CopyRawFrameDataToArray(pixels);
}
else
{
frame.CopyConvertedFrameDataToArray(pixels, ColorImageFormat.Bgra);
}
int stride = width * format.BitsPerPixel / 8;
return BitmapSource.Create(width, height, 96, 96, format, null, pixels, stride);

我已经决定在最后添加这段代码
BitmapSource bitmap= BitmapSource.Create(width, height, 96, 96, format, null, pixels, stride);
ScaleTransform scale=new ScaleTransform((Width / bitmap.PixelWidth),(Height / bitmap.PixelHeight));
TransformedBitmap tbBitmap = new TransformedBitmap(bitmap, scale);
return tbBitmap;所以完整的方法是:
private BitmapSource ToBitmap(ColorFrame frame)
{
int width = frame.FrameDescription.Width;
int height = frame.FrameDescription.Height;
PixelFormat format = PixelFormats.Bgr32;
byte[] pixels = new byte[width * height * ((PixelFormats.Bgr32.BitsPerPixel + 7) / 8)];
if (frame.RawColorImageFormat == ColorImageFormat.Bgra)
{
frame.CopyRawFrameDataToArray(pixels);
}
else
{
frame.CopyConvertedFrameDataToArray(pixels, ColorImageFormat.Bgra);
}
int stride = width * format.BitsPerPixel / 8;
BitmapSource bitmap= BitmapSource.Create(width, height, 96, 96, format, null, pixels, stride);
ScaleTransform scale=new ScaleTransform((640.0 / bitmap.PixelWidth),(480.0 / bitmap.PixelHeight));
TransformedBitmap tbBitmap = new TransformedBitmap(bitmap, scale);
return tbBitmap;
