EXTRACTION METHOD OF NEUTRAL CELL

摘要

PROBLEM TO BE SOLVED: To provide a method for generating a neutral cell in each joined component. SOLUTION: A neutral cell in a joined component is extracted by the following steps: (1) a step in which a neutral cell is extracted from CT measurement data; (2) a step in which a pseudo board thickness is calculated based on the distance between the surface points on the front side and rear side boundary cells closest to each surface point on the neutral cell; (3) a step which divides each neutral cell at least into the area of the non-joint part and the area of the joint part based on the pseudo board thickness; (4) a step in which a virtual neutral cell is created between the neutral cell and the body surface in the area of the joint part; (5) a step in which a coupled cell is created by connecting the virtual neutral cell and the neutral cell in the area of the non-joint part; and (6) a step in which a foreground cell assembly for each component is obtained from the coupled cell.
