测量设备相对于目标的俯仰和横摆

Question

I am newbie to vuforia, I would like to measure the device orientation relative to the target.

My idea was to use the projection matrix to get the rotation matrix decomposed from the projection matrix and then compute the orientation values.

Is there a simpler way or am I doing it wrong?

Answer 1

I could solve it using this matrix

I got the rotation matrix from the pose matrix and calculated the orientation from http://planning.cs.uiuc.edu/node103.html

Hope this helps someone.
