depth value puzzle

juerg

I try to capture the depth data with

PImage depth = kinect.GetDepth();

For a certain x,y pixel I try to get the depth value with:

depth.loadPixels();
println(depth.pixels[x + y*width]);

but get funny high negative values.

What' s the trick to get reasonable numbers?

that sounds like you are getting a colour

was able to prove that, get 3 equal byte values but only for distances > 1 m and with low resolution (starts with 230 and decreases for about every 5 cm by 1. Have not found a Kinect4WinSDK function equivalent to org.openkinect.processing.getRawDepht();
