用于Kinect深度视图和WPF的InteropBitmaps。 [英] InteropBitmaps for Kinect Depth view and WPF.

问题描述

在新的SDK中，骨架视图示例使用Microsoft.Samples.Kinect.WpfViewers来显示深度和RGB数据。这与前面的例子中的bitmapsource有什么区别？使用任何一个时，性能是否有差异？
另外，在项目中使用它的正确方法是什么？到目前为止，我已经采用了以下方法，但我并不确定imageHelper的功能是什么。谢谢，

In the new SDK the skeleton view example uses Microsoft.Samples.Kinect.WpfViewers to display depth and RGB data. What is the difference between that and bitmapsource from the previous examples? Is there a difference in performance when using either one? Also, what is the proper way to use it in a project? So far I've resorted to the following, but I'm not exactly sure that the function of imageHelper is. Thank you,

 

image_Kinect = e.ImageFrame.Image;

image_Kinect = e.ImageFrame.Image;

if（imageHelper = = null）

if (imageHelper == null)

{

imageHelper = new InteropBitmapHelper（image_Kinect.Width，image_Kinect.Height，image_Kinect.Bits）;

imageHelper = new InteropBitmapHelper(image_Kinect.Width, image_Kinect.Height, image_Kinect.Bits);

im_kinect.Source = imageHelper.InteropBitmap;

im_kinect.Source = imageHelper.InteropBitmap;

}

else

{

imageHelper.UpdateBits（image_Kinect.Bits）;

imageHelper.UpdateBits(image_Kinect.Bits);

im_kinect.Source = imageHelper.InteropBitmap;

im_kinect.Source = imageHelper.InteropBitmap;

}

推荐答案

KinectColorViewer中有评论，

There's a comment in KinectColorViewer,

      ;       // interopBitmap是一个WPF结构，可以重置图像的位。

            //这比每帧执行一次BitmapSource.Create调用更有效。

因此它只是一种从PlanarImage到ImageSource的更有效方式。

            //An interopBitmap is a WPF construct that enables resetting the Bits of the image.
            //This is more efficient than doing a BitmapSource.Create call every frame.
so it's just a more efficient way of going from a PlanarImage to an ImageSource.
