Getting Depth Value on Kinect SDK 1.6
- by AlexanderPD
this is my first try on Kinect and Kinect SDK so I'm having a lot of "newbie issues" :)
my goal is to point my mouse on the Kinect standard video output and get the depth value.
I already have both normal video and depth video outputs by using the 2 "Color Basic-WPF" and "Depth Basic-WPF" samples, and handling mouse events or position is not a problem.
In fact i already did all and i already got a depth value, but this value is always HIGHLY imprecise. It jumps from 500 to 4000 by just moving to the next pixel in a plane surface.
So.. I'm pretty sure I'm reading the depth value in the wrong way. This is how i read it:
short debugValue = depthPixels[x*y].Depth;
debug.Text = "X = "+x+", Y = "+y+", value = "+debugValue.ToString();
i know it's pretty out of context, this little piece of code is inside the same SensorDepthFrameReady function in "Depth Basic-WPF"! "x" and "y" are the mouse coordinates and depthPixels is DepthImagePixel[] type, a temporary array filled with the "depthFrame.CopyDepthImagePixelDataTo(this.depthPixels);" instruction.
Depth frame is filled here: DepthImageFrame depthFrame = e.OpenDepthImageFrame()
the "e" comes from here: private void SensorDepthFrameReady(object sender, DepthImageFrameReadyEventArgs e)
and this last one is called here: this.sensor.DepthFrameReady += this.SensorDepthFrameReady;
how i must handle that depth value i get? I know the value must be between 800 and 4000 but i get values between about 500 and about 8000.
i already google a lot (here on SO too) and i still can't understand if the depth value is 11 or 13 bit. The sdk examples uses shrink this value to 8 bit and this is making even more confusion in my head :(
