Abstract:
To provide a technology for accurately estimating the state change of an observation object, there are included a step for acquiring first sensor information that is obtained by observation of a state of an observation object at a first time by a periphery monitoring sensor (S100), steps for identifying the kind of the observation object based on the first sensor information and reading a purpose attribute of the observation object and an environmental factor from a purpose attribute storage unit that stores a purpose attribute that shows a use purpose or an observation purpose of the observation object and an environmental factor that affects the state change of the observation object (S104, S105), a step for retrieving a plurality of finite state series corresponding to the kind of the observation object from a finite state series storage unit that stores a finite state series that corresponds to the kind of the observation object and specifies a series of a plurality of state changes accompanying the time course and reducing the selection number of the plural finite state series to be retrieved, based on the purpose attribute of the observation object and the environmental factor (S108), a step for correcting the finite state series using the observation value of the observation object in the reduced finite state series (S119), and a step for outputting the corrected finite state series as a state prediction (S111).
