Title:
SHAPE MODELING DEVICE AND SHAPE MODELING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/044197
Kind Code:
A1
Abstract:
The present invention addresses the problem in which errors pertaining to a surface cannot be evaluated in a surface model obtained from a conventional point group. A shape modeling device (1), according to the present disclosure, comprises: a data input/output unit (2) that inputs point group data (5) and outputs surface model data (7); a surface approximation unit (8) or obtaining a surface shape that approximates point group data; a reliability calculation unit (9) that calculates the reliability of the surface shape; and a reliability imparting unit (10) that imparts reliability to form a surface model. This configuration enables achievement of a the shape modeling device (1) that uses an approximate surface model imparted with reliability that indicates certainty.
