POSITION DETECTION DEVICE, POSITION DETECTION METHOD, AND COMPUTER PROGRAM PRODUCT
First Claim
1. A position detection device comprising:
- a position estimation unit configured to estimate a position of a moving object based on an absolute position of the moving object and a position change of the moving object obtained from autonomous navigation; and
a position correction unit configured to correct, based on presence probability information which is information on each of a plurality of regions and indicates a higher probability as a presence frequency of the moving object is higher, the estimated position of the moving object so that the moving object is present at a position with a high probability.

Abstract
According to an embodiment, a position detection device includes a position estimation unit and a position correction unit. The position estimation unit is configured to estimate a position of a moving object based on an absolute position of the moving object and a position change of the moving object obtained from autonomous navigation. The position correction unit is configured to correct, based on presence probability information which is information on each of a plurality of regions and indicates a higher probability as a presence frequency of the moving object is higher, the estimated position of the moving object so that the moving object is present at a position with a high probability.
