US 2017/0324943 A1 · DRIVER-ASSISTANCE METHOD AND A DRIVER-ASSISTANCE APPARATUS

Abstract

A driver-assistance method and a driver-assistance apparatus are provided. In the method, a movement trajectory of wheels in surroundings of a vehicle when the vehicle moves are calculated. Multiple cameras disposed on the vehicle are used to capture images of multiple perspective views surrounding the vehicle, and the images of the perspective views are transformed into images of a top view. A synthetic image surrounding the vehicle is generated according to the images of the perspective views and the top view. Finally, the synthetic image and the movement trajectories are mapped and combined to a 3D model surrounding the vehicle and a movement image including the movement trajectories having a viewing angle from an upper rear side to a lower front side of the vehicle is provided by using the 3D model when backing up the vehicle.
