発明の名称 (英語) DEVICE FOR COMPUTING GEOMETRIC FEATURE VALUE OF CONSTRUCT, MEDICAL IMAGE ANALYSIS SYSTEM, REVERSE ENGINEERING ASSISTANCE SYSTEM, STRUCTURE OPTIMIZATION SYSTEM, AND PROGRAM FOR COMPUTING OF GEOMETRIC FEATURE VALUE NEW
発明の概要(英語) An objective of the present invention is to compute a geometric feature value of a construct without extracting a boundary of a shape of the structure in image data. Provided is a device for computing a geometric feature value of a construct, said device comprising: an image data acceptance part 1 for accepting two-dimensional or three-dimensional image data of a construct; a related value data computation part 2 for, by a virtual physical model using a linear partial differential equation, computing from the image data related value data indicating a value which is related to a geometric feature value of the construct; and a feature value data computation part 3 for computing from the related value data feature value data indicating the geometric feature value of the construct.
従来技術、競合技術の概要(英語) BACKGROUND ART
A general computer in an engineering (CAE) is incorporated, the dimensions of the shape of a structure, the distance from the boundary are determined by measurement.
Specifically, as shown in Patent Document 1, from the image data of the shape, the shape of the image processing using the extracted boundary (contour), the shortest distance from the boundary of a shape and dimension.
However, in the conventional image processing, in order to extract the boundary of the calculated approximate curve or the like is required, in the case of the image data of the STL data STL the calculation of a distance between elements is required, other, in order to obtain the geometric information necessary to perform various arithmetic operations.
