Dear AlessandroB:

First, thanks your help.

I found I use the  old sdk version. (2.6.7)

And then I update my sdk to 2.8.8 version.

I found the getPose() method of the TrackableResult class.

I want to know is there any example about the getPose() method?

Thanks!

The target position can be extracted from the target Pose; if you search the code for the "getPose()" method of the TrackableResult class, you'll find where this is called;

then, from the pose you can get the position following the maths explained here:
