Drive assisting system

Abstract

An object of the present invention is to provide a driving assistance system capable of displaying a picked-up image near a vehicle as a less-distorted image on a monitor. A driving assistance system according to the present invention comprises an imaging means () for picking up a surrounding image of a vehicle () on a road surface, an image translating means () for executing an image translation by using a three-dimensional projection model (), which is convex toward a road surface side and whose height from the road surface is not changed within a predetermined range from a top end portion of the vehicle () in a traveling direction, to translate the image picked up by the imaging means () into an image viewed from a virtual camera (), and a displaying means () for displaying an image translated by the image translating means (). The three-dimensional projection model () is configured by a cylindrical surface model () that is convex toward the road surface side, and a spherical surface model () connected to an end portion of the cylindrical surface model (). Accordingly, the straight line on the road surface, which is in parallel with the center axis of the cylindrical surface model (), is displayed as the straight line, and thus a clear and less-distorted screen can be provided to the driver.
