ROUTE INFORMATION GENERATION DEVICE AND ROUTE INFORMATION GENERATION METHOD
First Claim
1. A moving path information generating apparatus, comprising:
- an azimuth information acquisition section that acquires azimuth information by an azimuth information sensor;
an azimuth information change detection section that detects a change in the azimuth information acquired by the azimuth information acquisition section;
an azimuth information change information recording section that records azimuth information change information including the azimuth information acquired by the azimuth information acquisition section when the azimuth information change detection section has detected the azimuth information change;
a position acquisition determination section that commands position acquisition when the azimuth information change detection section detects the azimuth information change and position acquisition has not been commanded at the time of a previous azimuth information change;
a position acquisition section that receives a position acquisition command from the position acquisition determination section and performs position acquisition;
a position information recording section that records position information including a position acquired by the position acquisition section; and
a moving path information generating section that calculates a position that has not been acquired by the position acquisition section at the time of azimuth information change using the azimuth information change information and the position information, and generates moving path information.
