Abstract
Disclosed relates to a driving support apparatus including at least: a detection unit that detects a driving lane on which a user's vehicle and a front vehicle located in front of the user's vehicle are driving based on image data output from a camera; a first calculation unit that calculates a second front vehicle width for the front vehicle based on a first front vehicle width for the front vehicle measured on the image data, a first driving lane width for the driving lane measured on the image data, and a second driving lane width predetermined according to a characteristic of the driving lane; and a second calculation unit that calculates a distance from the front vehicle based on a focal length of the camera, the first front vehicle width, and the second front vehicle width, thereby precisely measuring the distance from the front vehicle based on camera image data.
