Moving body position detection system, moving body position detection apparatus, moving body position detection method, and computer-readable storage medium
First Claim
1. A moving body position detection system comprising:
- a dead reckoning navigation information acquisition unit that acquires dead reckoning navigation information on a moving body;
a position identification unit that identifies a position of the moving body on a link based on the dead reckoning navigation information on the moving body;
a link data acquisition unit that acquires current position link data on a current position link and neighboring link data on a neighboring link, the current position link being a link on which the position of the moving body identified by the position identification unit is located, the neighboring link connected to the current position link;
a comparison unit that compares the dead reckoning navigation information on the moving body with the current position link data and with the neighboring link data; and
a position update unit that updates the position of the moving body, identified by the position identification unit, based on a comparison result of the comparison unit,wherein;
the dead reckoning navigation information includes information on a direction of the moving body;
the link data acquisition unit acquires a direction of the current position link and a direction of the neighboring link; and
the comparison unit compares the direction of the moving body with the direction of the current position link and with the direction of the neighboring link.

Abstract
A moving body position detection system including a unit that acquires dead reckoning navigation information on a moving body; a unit that identifies a position on the moving body on a link based on the dead reckoning navigation information on the moving body; a unit that acquires current position link data on a current position link and neighboring link data on a neighboring link. The current position link is a link on which the moving body position is located, and the neighboring link is connected to the current position link. The system also includes a unit that compares the dead reckoning navigation information on the moving body with the current position link data and with the neighboring link data; and a unit that updates the position of the moving body based on a comparison result of the comparison unit.
