There is no 6-Dof motion estimation of objects

[JunjieLiuSWU]

I found that the motion of objects in the code is 3-Dof, but the paper claims that it estimates 6-Dof motion of objects. So where is the 6-Dof motion estimation of objects? The prediction of ego pose is 6-Dof, but the prediction of object pose is 3-Dof
