Abstract

To improve the accuracy of space map data used by an information terminal to estimate a self position.SOLUTION: An information processing device 1 has an image data acquisition unit 131 that acquires first imaging image data generated by imaging a space from an imaging terminal, a space map creation unit 132 that creates first space map data indicating a feature of the space by extracting first features from the first imaging image data, and a space map provision unit 133 that provides the first space map data to an information terminal 2. The image data acquisition unit 131 acquires second captured image data from the information terminal 2, the space map creation unit 132 creates second space map data indicating features of the space by extracting, from the second imaging image data, second features where the number of which is smaller than the number of the first features extracted from the first imaging image data, and the space map provision unit 133 provides the second space map data to the information terminal 2.SELECTED DRAWING: Figure 2
