Information processing device, information processing system, method, and program

An information processing system comprising:

• a mobile device;
• and an information processing device capable of communicating with the mobile device, wherein
• the information processing device includes
• a tracking target position estimation unit that calculates a tracking target estimated position that is an estimated position of a tracking target to be tracked by the mobile device, and
• a tracking target search unit that searches for the tracking target, and
• the tracking target search unit
• calculates one or more search routes connecting a current position of the mobile device and a position where the tracking target can exist,
• generates a search route list in which the calculated one or more search routes are arranged from a top in order of proximity to the tracking target estimated position, and
• selects a search route in order from the top of the generated search route list, and
• the mobile device
• moves according to the search route selected by the information processing device to search for the tracking target.

An information processing method executed in an information processing device,

• the information processing method comprising:
• a tracking target position estimation step of calculating, by a tracking target position estimation unit, a tracking target estimated position that is an estimated position of a tracking target to be tracked by a mobile device;
• and
• a step, by a tracking target search unit, of
• calculating one or more search routes connecting a current position of the mobile device and a position where the tracking target can exist,
• generating a search route list in which the calculated one or more search routes are arranged from a top in order of proximity to the tracking target estimated position, and
• selecting a search route in order from the top of the generated search route list, and moving the mobile device according to the selected search route to search for the tracking target.

An information processing method executed in an information processing system including a mobile device and an information processing device capable of communicating with the mobile device,

• the information processing method comprising:
• executing, by the information processing device,
• tracking target position estimation processing that calculates a tracking target estimated position that is an estimated position of a tracking target to be tracked by the mobile device;
• and
• processing that calculates one or more search routes connecting a current position of the mobile device and a position where the tracking target can exist, generates a search route list in which the calculated one or more search routes are arranged from a top in order of proximity to the tracking target estimated position, and selects a search route in order from the top of the generated search route list, and
• by the mobile device,
• moving according to the search route selected by the information processing device to search for the tracking target.

A program for causing an information processing device to execute information processing,

• the program comprising:
• a tracking target position estimation step of causing a tracking target position estimation unit to calculate a tracking target estimated position that is an estimated position of a tracking target to be tracked by a mobile device, and
• causing a tracking target search unit to
• calculate one or more search routes connecting a current position of the mobile device and a position where the tracking target can exist,
• generate a search route list in which the calculated one or more search routes are arranged from a top in order of proximity to the tracking target estimated position, and
• select a search route in order from the top of the generated search route list, and move the mobile device according to the selected search route to search for the tracking target.
