The present invention includes a search route processor that calculates a plurality of search routes between locations of a plurality of searchers belonging to a predetermined area and a search target based on position information of the search target acquired from a position information terminal held by the search target, and a plurality of portable terminals that is held by the plurality of searchers and displays the plurality of search routes calculated by the search route processor and personal information that identifies the search target. The search route processor compares the plurality of search routes with each other to identify a shortest first search route, issues a search command to corresponding one of the searchers on the first search route to cause the searcher to start searching along the first search route displayed on corresponding one of the portable terminals, updates the position information of the search target and the search routes as the search target moves, when a second search route is shorter than the first search route, issues a search command to corresponding one of the searchers on the second search route to cause the searcher to start the searching along the second search route displayed on corresponding one of the portable terminals.
摘要:
An information processing device is provided capable of preventing tightening on a communication bandwidth due to an increase in communication amount. In the information processing device (1), a sensor data cache unit (11) acquires a detection result from a sensor (17), and a position derivation unit (13) and an object detection unit (14) acquire host vehicle position/posture reliability information and object reliability information, respectively. The object detection unit (14) next generates difference information on the basis of a high accuracy map (DB12) and the object reliability information, and a transmission unit (18) transmits the difference information. Then a confidence level generation unit (15) generates a confidence level from the host vehicle position/posture reliability information and the object reliability information, and a data utilization determination unit (16) determines whether or not to upload the difference information on the basis of the confidence level.

A navigation system (10) suitable for installation in a host-vehicle (12) includes a navigation-device (26), a display (14), and a receiver (32). The navigation-device (26) is configured to determine a first-location (28) of the host-vehicle (12). The display (14) is configured to show navigation-information (38) to an operator of the host-vehicle (12). The navigation-information (38) indicates the first-location (28) relative to a map (30). The receiver (32) is configured to receive profile-information (34) associated with an other-vehicle (18). The profile-information (34) includes a second-location (36) of the other-vehicle (18). The system (10) indicates the second-location (36) on the map (30).
摘要:
A center (100) is provided with an information selecting section (121) for selecting posted pieces of information including a prescribed term from among a plurality of pieces of information posted by users, and a route searching section (140) for searching for a route for a mobile object based on the selected posted pieces of information. The center (100) delivers pieces of information indicating the route searched for by the route search section (140) to a navigation system (200) that has made a request.
摘要:
Systems, methods, apparatus, and computer program products are provided for identifying overlapping areas. For example, in one embodiment, telematics data can be collected as vehicles traverse various geographic areas. Then, the areas traversed by the vehicles can be displayed to identify overlapping areas.
