Conversion of RHS calculated rotation and translation to LHS Unity coordinate system

Hi , Working with a mobile AR application, I get the 3x3 rotation and translation data of detected object. Now I would like to feed the data to unity and apply to game object.

Several initial attempts failed while i tried to align axis of my AR engine which is RHS as illustrated below in figure:1

Unity 3d axis which is LHS ( and which i assume is as illustrated in figure2, please correct me if am wrong)

Can anyone guide me through steps on how to transform the rotation and translation matrices in to this unity coordinate system convention.
