Abstract
Sensor information acquisition section acquires surrounding information including three dimensional information of respective surrounding positions of subject vehicle, and positional information of subject vehicle. Road surface information extraction section generates road surface image in which acquired surrounding information is projected onto road surface on which subject vehicle is travelling. Environment image generation section generates environment image in which three dimensional information of respective surrounding positions included in surrounding information has been appended to positions corresponding to surrounding positions in generated road surface image. Based on acquired positional information of subject vehicle, stored image acquisition section acquires stored image corresponding to positional information of subject vehicle from database. Image matching section matches generated environment image against acquired stored image. Estimation section estimates amount of displacement in positional information of subject vehicle based on obtained matching result.
