METHOD OF DATA ACQUISITION FOR THREE-DIMENSIONAL IMAGING

摘要

PROBLEM TO BE SOLVED: To provide a method of acquiring three-dimensional (3D) surface data of an object scene such as an intra-oral cavity.

SOLUTION: A three-dimensional imaging apparatus is positioned to acquire 3D data regarding a measuring view field. The three-dimensional imaging apparatus is translated while maintaining directional view of the object scene. The three-dimensional apparatus acquires the 3D data of the translated measuring view field. The data are registered into the 3D data for a start point in the object scene. The 3D data of the positioned and translated measuring view field prescribe a backbone 3D data set. The three-dimensional imaging apparatus is positioned so that the measuring view filed includes a second part of the directional view of the object scene, and acquires the 3D data overlapping part of the backbone 3D data set in the measuring view field. The 3D data overlapping the part of the backbone 3D data set are joined to the backbone 3D data set.
