我正在尝试使用 WPF 应用程序显示 Kinect 传感器检测到的玩家数量。除了显示玩家数量之外，我还根据他们与 Kinect 的距离为像素着色。最初的目标是测量像素的距离并显示距离，但我还想显示框架中有多少人。这是我现在正在使用的代码片段。
PS 我从THIS教程中借用了这个想法，我正在使用 SDK 1.8 和 XBOX 360 Kinect (1414)
private void _sensor_AllFramesReady(object sender, AllFramesReadyEventArgs e)
{
using (DepthImageFrame depthFrame = e.OpenDepthImageFrame())
{
if (depthFrame==null)
{
return;
}
byte[] pixels = GenerateColoredBytes(depthFrame);
int stride = depthFrame.Width * 4;
image.Source = BitmapSource.Create(depthFrame.Width, depthFrame.Height,
96, 96, PixelFormats.Bgr32, null, pixels, stride);
}
}
private byte[] GenerateColoredBytes(DepthImageFrame depthFrame)
{
//get the raw data from kinect with the depth for every pixel
short[] rawDepthData = new short[depthFrame.PixelDataLength];
depthFrame.CopyPixelDataTo(rawDepthData);
/*
Use depthFrame to create the image to display on screen
depthFrame contains color information for all pixels in image
*/
//Height * Width *4 (Red, Green, Blue, Empty byte)
Byte[] pixels = new byte[depthFrame.Height * depthFrame.Width * 4];
//Hardcoded loactions for Blue, Green, Red (BGR) index positions
const int BlueIndex = 0;
const int GreenIndex = 1;
const int RedIndex = 2;
//Looping through all distances and picking a RGB colour based on distance
for (int depthIndex = 0, colorIndex = 0;
depthIndex < rawDepthData.Length &&
colorIndex<pixels.Length; depthIndex++, colorIndex+=4)
{
//Getting player
int player = rawDepthData[depthIndex] & DepthImageFrame.PlayerIndexBitmask;
//Getting depth value
int depth =rawDepthData[depthIndex]>>DepthImageFrame.PlayerIndexBitmaskWidth;
//.9M or 2.95'
if (depth <=900 )
{
//Close distance
pixels[colorIndex + BlueIndex] = 0;
pixels[colorIndex + GreenIndex] = 0;
pixels[colorIndex + RedIndex] = 255;
//textBox.Text = "Close Object";
}
//.9M - 2M OR 2.95' - 6.56'
else if (depth >900 && depth<2000)
{
//Bit further away
pixels[colorIndex + BlueIndex] = 255;
pixels[colorIndex + GreenIndex] = 0;
pixels[colorIndex + RedIndex] = 0;
}
else if (depth > 2000)
{
//Far away
pixels[colorIndex + BlueIndex] = 0;
pixels[colorIndex + GreenIndex] = 255;
pixels[colorIndex + RedIndex] = 0;
}
//Coloring all people in Gold
if (player > 0)
{
pixels[colorIndex + BlueIndex] = Colors.Gold.B;
pixels[colorIndex + GreenIndex] = Colors.Gold.G;
pixels[colorIndex + RedIndex] = Colors.Gold.R;
playersValue.Text = player.ToString();
}
}
return pixels;
}
目前的目标是——
- 检测检测到的玩家总数并将其显示在
textBox - 根据距离逻辑为它们着色，即
depth <=900 is red。
使用当前代码，我可以检测到玩家并将它们涂成金色，但是一旦检测到玩家就会image冻结，而当玩家离开框架时，就会image解冻并正常运行。是因为循环吗？欢迎提出想法、指导、推荐和批评。
谢谢！
