适用于Windows的Kinect v2:在C#中调整颜色框的大小 [英] Kinect v2 for windows: resize color frame in c#

问题描述

任何人都知道，如果可能的话，如何降低kinect帧分辨率以实现色彩流动?因为全高清尺寸对于我的示波器来说太大了. 我找到了完整高清帧的代码:

anyone know, if it's possible, how to decrease the kinect frame resolution for color flow? because the full-hd size is too high for my scope.Thanks I have found this code for full hd frame:

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);


    }

推荐答案

我解决了在最后添加此代码的问题

i have resolved adding this code at the end

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;
    }
