Navigation system |
摘要 |
A navigation system includes: an angular velocity sensor 1 for detecting a change in an advancement direction of a vehicle; a vehicle azimuth calculation unit 13 for calculating a vehicle azimuth on the basis of angular velocity sensor information obtained from the angular velocity sensor; an on-board camera 2 for shooting a periphery of the vehicle; an image recognition unit 19 for recognizing an image obtained from the on-board camera; and an offset voltage correction unit 21 for performing a drift correction on the angular velocity sensor in accordance with an angle error between the vehicle azimuth calculated by the vehicle azimuth calculation unit and a vehicle azimuth determined from a white line on a road recognized by the image recognition unit.
