摘要
An object of the present invention is to reduce a memory capacity for realizing a search for information unique to a space. A computer is associated with each small space when a predetermined region of a virtual space is divided into a plurality of small spaces each having a similarity to a unit region and a similarity ratio being a power of two. It is made to function as a list management unit that acquires a list holding a feature amount and searchable by an index. (1) Finding the index of the small space when it is assumed that there is a small space having the similarity ratio and the reference point, and (2) Searching the list by the found index once or This is performed a plurality of times while changing the similarity ratio of interest to function as a search unit that searches for a feature amount of a small space corresponding to a reference point.
