A multi-dimensional solution directed to employment of a low-resolution motion tracking technique to estimate a homogeneous transformation matrix that is further adapted to accurately characterize movement/motion between successive positions of an object through time. Low-resolution tracking is first used to estimate a homogeneous transformation matrix that describes the motion between successive positions of an object as that object moves over time. The 3-dimensional imaging data is then used to calculate a more accurate homogeneous transformation matrix, providing the accuracy to better characterize motion of the object over time. In the case where the 'object' being tracked is a 3-dimensional imaging system (herein, 3DIS), the resulting homogeneous transformation matrix is used to create 3-dimensional digital models of the scene that is in the field-of-view of the 3-dimensional imaging system (3DIS).
