  • Publication number: 20240100698
    Abstract: The observation update unit (152) increases a weight of a particle for a particle representing a position and a posture closer to a position and a posture of an operation object indicated by an observation result, and increases a weight of a corresponding particle for a particle closer to a state in which an object of interest and the operation object arranged in a position and a posture represented by each of particles are in contact with each other in a virtual space where shapes and a relative positional relationship of the object of interest and the operation object are expressed in a case in which the observation result indicates that the contact has occurred. A state estimation unit (154) calculates an estimated state that is a position and a posture of the operation object estimated based on a set of the particles in which a weight of each of the particles is adjusted.
