AI Technical Summary

Technical Problem

Existing methods struggle to generate a realistic three-dimensional model of an individual's entire body for participation in virtual reality (VR) spaces, particularly in web conferences, as they typically only create a 3D image of the upper body.

Method used

A system that generates a three-dimensional model of the entire body by combining a captured image of the upper body with a selected three-dimensional model of the lower body, using attributes like gender and clothing analysis to match the upper and lower body models, and adjusting scale and position for a seamless integration.

Benefits of technology

Enables the easy generation of a whole-body three-dimensional model for VR spaces, enhancing realism by accurately representing the user's appearance and motion, thereby improving the sense of presence in virtual environments.

Abstract

To easily generate a three-dimensional full-body model for participation into a VR space.SOLUTION: A three-dimensional model generation device includes: an upper half-body model generation unit for generating a three-dimensional upper half-body model on the basis of captured image information about an upper half-body of an imaging subject obtained by an imaging device; and a lower half-body model selection unit for analyzing attributes of the imaging subject on the basis of the captured image information, and selecting a three-dimensional lower half-body model for the upper half-body of the imaging subject from a plurality of preset three-dimensional lower half-body models.SELECTED DRAWING: Figure 1
