This paper proposes a novel method on 3D fitting simulation of eyeglass frames to individual faces. First, we formulate the fitting operation of the eyeglass frames to the individual faces at real optical shops. We utilize the analogy of the structure between eyeglass frames and robot arms. Under the analogy, the bending angles on eyeglass frames correspond to the rotating angles on robot arms. Then, we extract the simultaneous structural conditional equations which are derived from the matrix equation on a closed loop along the base to the end-effector through the arms using inverse kinematics. We can obtain the optimum bending angles by solving the equations using the Newton-Raphson method. Finally, we will show some examples applied for several frame types and individuals. As a result, it is confirmed that the proposed method is very effective.
