> how do you get thoses values ? To get the depth values you shoudl retrieve the MEASURE::DEPTH which is a one channel matrix containing Z values. It looks like you display Point Cloud values from this sample: In this case the Depth (Z) is the 3rd value. Its unit depends the InitParameters you set.
