Processing apparatus and method for creating avatar

Abstract

A processing apparatus for creating an avatar is provided. The processing apparatus calculates skeleton sizes of joints of the avatar and local coordinates corresponding to sensors attached to a target user, by minimizing a sum of a difference function and a skeleton prior function, the difference function representing a difference between a forward kinematics function regarding the joints with respect to reference poses of the target user and positions of the sensors, and the skeleton prior function based on statistics of skeleton sizes with respect to reference poses of a plurality of users.
