Movement space information processing system, movement space information processing method, and communication device

A movement space information processing method of exchanging information with moving bodies movable in a space to thereby create spatial information including information related to the space, each moving body transmitting moving-body information item including at least position information regarding a position of the corresponding moving body, the method comprising:

• acquiring the moving-body information items transmitted from the respective moving bodies using communications therewith;
• analyzing the position information included in each of the moving-body information items to thereby determine, from the moving bodies, one or more moving bodies that are movably located within a predetermined movement range in the space;
• identifying, from the determined one or more moving bodies, at least one moving body to accordingly perform a setting task of setting the identified at least one moving body as at least one representative moving body;
• receiving, from the at least one moving body being set as the at least one representative moving body, the moving-body information item including probe information, the probe information being related to the space and extracted by the at least one representative moving body from an image of the space;
• performing development of the spatial information based on the received probe information;
• and
• determining, based on a degree of the development of a content of the spatial information related to the movement range, a representative moving-body ratio of the number of the at least one moving body identified as the at least one representative moving body to a total number of the determined one or more moving bodies that are movably located within the predetermined movement range.

A communication device to be mounted to an own moving body, the communication device comprising:

• a self-information item acquisition unit configured to acquire a self-information item including a destination of the own moving body;
• an other-body information acquisition unit configured to acquire an other-body information item from each of other moving bodies located around the own moving body, the other-body information item of each of the other moving bodies including a destination of a corresponding one of the other moving bodies;
• a moving-body group setting unit configured to:
• use the self-information item and the other-body information item to select, from the other moving bodies, at least one other moving body with the destination that is identical to the destination of the own moving body;
• and
• combine the own moving body and the selected at least one other moving body with each other into a group;
• a representative setting unit configured to set one of the own moving body and the selected at least one other moving body in the group as a representative moving body;
• and
• a transmission unit configured to transmit, to a base station, information regarding the own moving object and the at least one other moving object in the group in response to the own moving object being set as the representative moving body.
