1. A driving assist method for generating an overhead image from image data obtained from successive images captured by an imaging device mounted on a vehicle, comprising the steps of:
- obtaining relative distances between the vehicle and an obstacle based on signals from an obstacle detection device mounted on the vehicle as the vehicle moves;
correlating the image data obtained from successive images with the relative distances; and
projecting the image data on a projection plane to generate the overhead image.

Abstract
A driving assist apparatus obtains image data from a camera mounted on a vehicle and stores the image data in an image memory. The driving assist apparatus further obtains a relative distance between the vehicle and an obstacle on the basis of input from a sonar device mounted on the vehicle, generates a projection plane on the basis of the relative distance between the vehicle and the detected obstacle, and projects the stored image data onto a plane to generate an overhead image.
