A drive assisting system capable of displaying an image picked up in the vicinity of a vehicle as a monitor image where distortion is suppressed. The drive assisting system comprises means (2) for picking up the circumferential image of a vehicle (1) on the road surface, means (3) for performing image conversion using a three-dimensional projection model (300) convex to the road surface side and having an invariant height from the road surface within a specified range from the end part of the vehicle (1) in the traveling direction at the time of converting an image picked up by the image pickup means (2) into an image viewed from an imaginary camera (2a), and means (4) for displaying the image converted by the image converting means (3). The three-dimensional projection model (300) comprises a tubular surface model (301) convex to the road surface side, and a spherical surface model (302) continuous to the end part of the tubular surface model (301). Since a line on the road surface parallel with the central axis of the tubular surface model (301) becomes a line in the converted image, a driver can be presented with an easy-to-see screen where distortion is suppressed. |
