原始深度数据到文本 Kinect v1.0 C#

Question

我一直在互联网上搜索，但没有任何运气。我正在使用带有 Kinect SDK v1.0 的 Xbox Kinect。我想获取原始深度数据并将其转换为文本文档，以便我可以使用深度数据。我在这个网站上找到了一些东西，但它是针对 Beta2 的，我需要使用 v1.0。感谢任何帮助，但我是编码新手，所以示例代码是最好的。

使用版本 1.5.0.1 这非常简单，它实际上与版本 1.0 相同，并且可以使用它。完成此操作所需的只是 A( 保存深度数据的short[] B(将数据移动到数组DepthImageFrame，以及 C(保存数据的StreamWriter。

添加一个short[]来存储深度数据，并在DepthFrameReadyEventArgs(或AllFramesReadyEventArgs(中"使用"DepthImageFrame：

 short[] depthData;
 ...
 using (DepthImageFrame depthFrame = e.OpenDepthImageFrame(()) //create a new frame every time one is ready
 {
       //assign a value to depthData
       depthData = new short[depthFrame.PixelDataLength];
 } 

然后，您可以使用DepthImageFrame.CopyPixelDataTo将每个帧的深度添加到depthData

 using (DepthImageFrame depthFrame = e.OpenDepthImageFrame(()) //create a new frame every time one is ready
 {
       //assign a value to depthData
       depthData = new short[depthFrame.PixelDataLength];
       //add raw depth data to depthData
       depthFrame.CopyPixelDataTo(depthData);
 } 

然后我们可以编写一种方法来保存我们的数据 使用StreamWriter .

 private void SaveDepthData(short[] depthData)
 {
       //initialize a StreamWriter
       StreamWriter sw = new StreamWriter(@"C:/Example.txt");
       //search the depth data and add it to the file
       for (int i = 0; i < depthData.Length; i++)
       {
            sw.WriteLine(depthData[i] + "n"); //n for a new line
       }
       //dispose of sw
       sw.Close();
 }      
 ...
 SaveDepthData(depthData);

希望这有帮助！
