TRACK INFORMATION GENERATING DEVICE, TRACK INFORMATION GENERATING METHOD, AND COMPUTER-READABLE STORAGE MEDIUM
First Claim
1. A track information generating device comprising:
- a self-contained navigation track acquisition unit that acquires a self-contained navigation track that is a track of a vehicle, indicated by time-series pieces of self-contained navigation information;
a GPS track acquisition unit that acquires a GPS track that is a track of the vehicle, indicated by time-series pieces of GPS information; and
a self-contained navigation information correcting unit that compares the self-contained navigation track with the GPS track to acquire a first correction amount for obtaining the highest degree of coincidence between the self-contained navigation track and the GPS track and then to correct the self-contained navigation information using a second correction amount that is smaller than the first correction amount.

Abstract
Track information generating devices, methods, and programs acquire a self-contained navigation track of a vehicle indicated by time-series pieces of self-contained navigation information, and acquire a GPS track that is a track of the vehicle indicated by time-series pieces of GPS information. The devices, methods, and compare the self-contained navigation track with the GPS track to acquire a first correction amount for obtaining the highest degree of coincidence between the self-contained navigation track and the GPS track and then correct the self-contained navigation information using a second correction amount that is smaller than the first correction amount.
