关于MapSkeletonPointToDepthPoint API [英] About the MapSkeletonPointToDepthPoint API

问题描述

我正面临一个让我烦恼的奇怪问题。

我尝试使用  MapSkeletonPointToDepthPoint函数来获取指定关节的深度。

以下是我的测试代码的一部分。

它位于&_bspns_AllFramesReady事件处理程序中，以确保我得到了相同帧的骨架和深度。

 foreach（skeletonData中的骨架骨架）
 {
 if（skeleton.TrackingState == SkeletonTrackingState.Tracked）
 {
 SkeletonPoint skeHipCenter = skeleton.Joints [JointType.HipCenter] .Position; 
 DepthImagePoint hipCenter = this._sensor.CoordinateMapper.MapSkeletonPointToDepthPoint（skeHipCenter，DepthImageFormat.Resolution640x480Fps30）; 
 
 int index = hipCenter.X + hipCenter.Y * 640; 
 + hipCenter.X.ToString（）+" ，" + hipCenter.Y.ToString（）+"）"）; 
 
 Console.WriteLine（" Origin =" + _depthPixels [index] .Depth.ToString（））; 
 
 Console.WriteLine（" Mapped =" + hipCenter.Depth.ToString（））; 
} 
} 

但是，我发现MapSkeletonPointToDepthPoint函数的深度与深度不匹配在深度框架中从深度框架复制。

我用Kinect Studio的深度查看器检查，我发现从x，y坐标映射的深度与深度查看器的深度匹配。 / p>

那么，有什么不对吗？例如，我误解了MapSkeletonPointToDepthPoint函数的用法。

感谢您耐心阅读此问题：）

解决方案

深度值减去多少？您是否也比较了相邻的像素？请记住，骨架深度代表特定关节计算的身体区域。映射到深度时，通常需要分析关节周围的区域。
联合位置可能不一定是一个像素值。

Hi, I'm facing a weird problem that annoying me a lot.

I try to use the MapSkeletonPointToDepthPoint function to get the depth of specified joint.

The following is part of my code for test.

It's in the _sensor_AllFramesReady event handler to make sure that I get the skeleton and depth at the same frame.

   foreach (Skeleton skeleton in skeletonData)
   {
      if (skeleton.TrackingState == SkeletonTrackingState.Tracked)
      {
         SkeletonPoint skeHipCenter = skeleton.Joints[JointType.HipCenter].Position;
         DepthImagePoint hipCenter = this._sensor.CoordinateMapper.MapSkeletonPointToDepthPoint(skeHipCenter, DepthImageFormat.Resolution640x480Fps30);
                                                        
         int index = hipCenter.X + hipCenter.Y * 640;
                             + hipCenter.X.ToString() + " , " + hipCenter.Y.ToString() + ")");                            
                           
         Console.WriteLine("Origin = " + _depthPixels[index].Depth.ToString());
                            
         Console.WriteLine("Mapped = " + hipCenter.Depth.ToString());
      }                        
   } 

However, I found that the depth from the MapSkeletonPointToDepthPoint function doesn't match with depth in the depth array copy from the depth frame.
And I checked with the depthviewer of Kinect Studio, I found that the depth mapped from the x, y coordinate is just matched with the depth of depthviewer.

So, is there something wrong? For example, I misunderstood the usage of MapSkeletonPointToDepthPoint function.

Thank you for your patience to read this question : )

解决方案

How much is the depth value off by? Have you compare adjacent pixels as well? Keep in mind the skeletal depth represents an area of the body for a particular joint calculation. When mapped to depth, you typically want to analyze the area around the joint. A joint position may not necessarily be one pixel value.
