We consider a lost information recovery algorithm to gap filling. We propose the algorithm to lost joint angles recovery with the mathematical model of 3DOF skeletal model motion, parameter identification and force plate data. It has been applied to gap filling of angle between shin and horizont in time of deep squat when skin markers disappear and the angles cannot be calculated.
Key words: optical motion capture system, gap filling, force plate, mathematical model, information integrity.
