Information processing device and information processing method

An information processing method implemented by a receiver, an obtainer, a generator and a transmitter, the method comprising:

• receiving, by the receiver, a route information including two or more target positional information included in an inquiry from a user terminal;
• obtaining, by the obtainer, two or more images associated with a positional information satisfying a first positional condition from a mobile body, the first positional condition being a condition that the positional information of the mobile body identifies the position having an approximate relationship with the position identified by each of the two or more target positional information included in the route information, each of the two or more images being associated with a first attribute value set including one or more environment information which includes the positional information for identifying a capturing position or associated with a second attribute value set including two or more environmental information which includes both the positional information for identifying the capturing position and a first time information for identifying a capturing time;
• generating, by the generator, a combined image by combining the two or more images obtained by the obtainer and associated with different time information from each other in a time series manner or generate a merged image by merging a part of the two or more images obtained by the obtainer and associated with different positional information from each other in a spatial manner;
• and
• transmitting, by the transmitter, the combined image or the merged image generated by the generator.
