Abstract

A driving support system which includes: at least two cameras take images of areas around a vehicle, whose ranges of field of view partially overlap with each other; a control unit performing a predetermined coordinate transformation on the images taken by the cameras and joining the transformed images together to produce an overhead view image; and a display unit to display the overhead view image. The control unit changes the position of the joint of the transformed images in the overhead view image.

Description

technical field [0001] The invention relates to a driving support system and a method of generating an overhead image. Background technique [0002] Japanese Patent Application Laid-Open No. 2002-125224 discloses a driving support system that provides a driver with a virtual image of an area around a vehicle viewed from a virtual viewpoint located above the vehicle (hereinafter referred to as "overhead image"). In this system, a plurality of cameras are installed on the vehicle to capture images of the surrounding area of ​​the vehicle, and each image of the surrounding area of ​​the vehicle is processed and transformed into a constituent image of an overhead view image. The top view is a composite image of each component image and the top view image of the vehicle, presenting the driver with visual information of the vehicle's position relative to the marking line of the parking space or the curb when parking or driving to the curb. [0003] In the driving support system d...
