- 초록
- An apparatus includes: an input/output interface configured to have a reference surface model and a floating surface model inputted thereto; a memory having instructions for registration of the reference surface model and the floating surface model stored therein; and a processor configured for registration of the reference surface model and the floating surface model according to the instructions. The instructions perform: selecting initial transformation parameters corresponding to the floating surface model by comparing depth images of the reference surface model and the floating surface model; transforming the floating surface model according to the initial transformation parameters; calculating compensation transformation parameters through a matrix calculated by applying singular value decomposition to a cross covariance matrix between the reference surface model and the floating surface model; and transforming the floating surface model according to the compensation transformation parameters, and executing registration of the reference surface model and the floating surface model.
