Abstract
Calculating a highly accurate locus is a goal. An administrative part () for correcting a traveling locus of a mobile object (V) is characterized by including an evaluation function generating unit () that sets a plurality of nodes on locus data of the mobile object (V) acquired by a wheel rotation quantity measuring unit (), correlates position data of the mobile object (V) acquired by the wheel rotation quantity measuring unit () to the nodes and correlates position data of the mobile object (V) acquired by other units of measurement means than the wheel rotation quantity measuring unit to the nodes, represents positions at which the nodes may occur by probability, represents positions at which position data correlated to the nodes may occur by probability, and calculates an evaluation function including the nodes and the position data as variables, based on each probability; and a locus optimization calculation unit () that calculates a locus on which each node occurs with largest probability, based on the evaluation function.
