Title:
DRIVING SUPPORT DEVICE
Document Type and Number:
Japanese Patent JP3871614
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To display a pickup image in the vicinity of a vehicle on a monitor as an undistorted image.
SOLUTION: This driving support device is constituted of an imaging means 2 for imaging the periphery of the vehicle 1 on a road surface, an image converting means 3 for converting an image by using a three-dimensional projection model 300 having a projecting shape on the road surface side and unchanging in the height from the road surface in a prescribed range from an advancing directional end part of the vehicle 1 when converting the pickup image by the imaging means 2 into an image looked from a virtual view point 2a and a display means 4 for displaying the image converted by the image converting means 3. The three-dimensional projection model 300 is composed of a cylindrical surface model 301 having a projecting shape on the road surface side and a spherical surface model 302 continuing with an end part of this cylindrical surface model 301. Thus, a straight line on the road surface parallel to the axis of the cylindrical surface model 301 becomes a straight line in the converted image so that an easy-to-see and undistorted image screen can be presented to a driver.
