Abstract
A vicinity supervising device of a vehicle includes an image capturing unit capturing a plurality of images at different locations; a distance acquiring unit acquiring a distance up to the object detected by transmitting and receiving probing waves from/to the object; a first offset calculation unit calculating a first parallax offset value based on the plurality of images and the distance up to the object; and a second offset calculation unit calculating a second parallax offset value based on a change in a parallax in a predetermined period at an identical point among the plurality of images and a travel distance of the vehicle travelling in a predetermined period; and a parallax correction unit correcting the parallax using the first parallax offset value under a condition where a difference between the first parallax offset value and the second parallax offset value is less than or equal to a threshold.
