Provided is a full-body modeling method and apparatus based on new model predictive control (MPC) with a visuomotor system in which visual perception and full-body motion control are integrated. The full-body modeling method includes determining a partial observation value associated with a state of an object based on a point of sight of a character, estimating the state of the object using the determined partial observation value based on a partially observable Markov decision process (POMDP), controlling a state of the character based on the estimated state of the object, and visualizing a motion of the character.
