Coordinates system in Vuforia

By red112 on Mon, 05/13/2013 - 10:22

Hello.

I'm new at Vuforia and want to get camera pose relative to the target.

I found the method getPose, and it returns the target pose of the target.

Then, what coordinate system is the getPose method uses? Is it the camera coordinate system?? ( I guess....)

(Is this Unified coordinate system???? There are some track talking about UCS, but I don't know what it is exactly.)

I had test with a known target and extracted the 3X4 matrix return with the getPose of the TrackableResult.

I guess the left one is the base coordinate system. 

 

Is it right??

If it is not correct, please let me know about the base coordinate system of Vuforia or ....

In What coordinate system does getPose present the target pose?

Hi, the getPose() method returns the reference frame of the target represented in the camera reference frame;

note:

the camera reference frame is defined with XY plane parallel to the screen and Z entering the screen;
