摘要

The present invention relates to a method for generating an exaggerated expression reflecting an individual tendency, the method for generating an exaggerated expression reflecting an individual tendency in a method for generating an exaggerated expression using a three-dimensional face model that can generate an expression through the movement of virtual muscle, (a) acquiring motion data according to facial expression change from a live image of a model to which a plurality of markers are attached, and calculating motion vector and exaggerated motion vector according to facial expression change from the obtained motion data; (b) Calculate the distance value between markers according to facial expression change from the live-action image of the model for each personality type with a plurality of markers divided according to the personality type test result, and use the calculated distance value generating a rate mapping table); (c) calculating an exaggeration index for each personality type using the generated rate mapping table; (d) receiving a two-dimensional image of an individual and generating a three-dimensional face model for each individual using the inputted two-dimensional image of the individual and the three-dimensional face model; (e) calculating the exaggeration index for each personality type by receiving the personality type and the exaggeration rate information of the individual; And (f) applying the calculated exaggeration index for each personality type to the exaggerated motion vector, and applying the result to the virtual muscle to generate an exaggerated expression reflecting individual inclination in the individual three-dimensional face model. It is a method of generating exaggerated expressions reflecting personal tendencies.;According to the present invention, since the exaggerated expression is generated by analyzing / reflecting the results of the disposition of various subjects and the characteristics of the facial expressions of each inclination, the exaggerated expression may be more realistic and reflect the individual's inclination. Since it can be arbitrarily adjusted by the user, there is an advantage that an exaggerated expression of various scales can be generated.;Personal orientation, personalized face model, exaggeration, exaggeration, motion vector, personality type, virtual muscle
