Three-dimensional model generation system

Abstract

The goal is to easily generate a three-dimensional model of an object from a paper drawing representing that object. [Solution] A system for generating a three-dimensional model of an object to be modeled, The imaging means 31 of the three-dimensional model generation system 30 captures a paper drawing 20 in which multiple figures 20a representing the object 19, consisting of the object to be modeled 10 or its constituent elements 11 to 14, are viewed from different directions, thereby obtaining graphic image data 39 of the object 19. The graphic image data 39 is input to the generation unit 40. The generation unit 40 is composed of, for example, an AI system that stores a trained model 41, and the trained model 41 generates a three-dimensional model 49 of the object 19 from the graphic image data 39.
