SHAPE DATA GENERATION METHOD AND APPARATUS

摘要

A shape data generation method includes: generating a target shape of transformation from plural tomographic images of an object; specifying, from among plural vertices of a first shape that is a reference shape of the object, plural first vertices, each first vertex of which satisfies a condition that a normal line of the first vertex passes through a point that is located on the target shape and is located on a boundary of the object in any one of the plural tomographic images; identifying, for each of the plural first vertices, a second vertex that internally divides a segment between the first vertex and the point; transforming the first shape so as to put each of the plural first vertices on a corresponding second vertex; setting a shape after the transforming to the first shape; and executing the first specifying and the subsequent processings a predetermined number of times.

1. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a process, the process comprising:
generating data of a target shape of transformation from a plurality of tomographic images of an object; first specifying, from among a plurality of vertices of a first shape that is a reference shape of the object and is to be transformed, a plurality of first vertices, each first vertex of which satisfies a condition that a normal line of the first vertex passes through a certain point that is located on the target shape and is located on a boundary of the object in any one of the plurality of tomographic images; second specifying, for each of the plurality of first vertices, a second vertex that internally divides a segment between the first vertex and the certain point; transforming the first shape so as to put each of the plurality of first vertices on a corresponding second vertex; setting a shape after the transforming to the first shape; and executing the first specifying, the second specifying, the transforming and the setting a predetermined number of times.
