Virtual clothing modeling apparatus and method
First Claim
1. A virtual clothing modeling apparatus comprising:
- a camera to obtain an image sequence including a plurality of images of a person who tries on clothing;
a storage unit to store clothes data including three-dimensional figures of clothes and patterns thereof, three-dimensional figure data of the person, and posture data of the person;
a posture-estimating unit to estimate the posture of the person in the images within the image sequence by using the image sequence and the stored posture data;
a time series posture data generating unit to generate time series posture data by using the estimated posture data of the person;
a clothes-simulating unit to estimate the motions of the clothes tried on by the person by using the three-dimensional figure data of the person, the clothes data, and the time series posture data;
a clothes image-generating unit to generate images of the clothes based on the estimated motions of the clothes; and
a synthesizing unit to synthesize images of the clothes on the person in the image sequence by using the estimated motions of the clothes and the clothes data.

Abstract
Trying on the clothes is simulated by processing an image sequence by using a posture dictionary, and a three-dimensional figure, obtained in advance, of a person who wishes to try on clothing. The process includes estimating the posture of the person, and simulating the motions of the clothes, in agreement with estimated time series posture data. A virtual modeling apparatus comprises an imaging device configured to take an image sequence, a posture-estimator which estimates the posture of a person in the image sequence from the three-dimensional figure data of the person and from data for various postures, a posture corrector which generates smooth and natural posture time series data from the time series of estimated postures, a clothes simulator which calculates the motions of the clothing being modeled, and a display device which displays images of the person as if they were actually wearing the clothing.
