what the unit of measurement returned by ConvertProjectiveToRealWorld ?

[Shlomo Zippel]

Hey,

Millimeters from the sensor. Note that the Z coord doesn't change,
only X & Y (They are converted from distance in pixels from the top
left of the depthmap to distance in mm from the sensor).

Cheers,
Shlomo

[Jae Yong Sung]

Which direction is X and which is Y?

Is X towards sideways?

Thanks for help

Jae

Hi

Attached please find a drawing that may help you to better understand the directions

In OpenNI, real world Y is up (we changed it from previous versions).

[Moshe Blitz]

Sorry. I attached an old drawing

Here is the correct one

Very interesting.

But if I want the information about Z in the Real World (for each pixel of projective), is it possible to obtain it whit ConvertProjectiveToRealWorld ?

there is a way to do it using other class?

Thanks!

The information in XnPoint3D when you use ConvertProjectiveToRealWorld
or viceversa is not changed.

Iker.

What Iker is trying to say is that Z value is always in real world.
