Element data management device, element data management method, program and data structure of element data

摘要

Problem to be solved: to provide an element data management apparatus, an element data management method, a program and a data structure of element data which can improve the utilization value of the environmental map.Element data storage (40) includes environmental data generated based on the sensing data acquired by the tracker and sensing time data corresponding to the time range in which the presence in the real space of the element is estimated based upon the time when the element representing the environmental data is sensed At least one element data is stored.The element data updating section (48) specifies the element data associated with the additional environmental data which is part or all of the environmental data based on the environmental data generated based on the new sensing data.An element data update section (48) associates element data containing additional environmental data into the element data to be identified.
