Abstract
A method for assisting in parallel parking includes providing a vehicle with a forward-looking camera and/or a backward-looking camera. The camera is used to capture an image of a parking area including at least one unoccupied parking space and a plurality of parking spaces occupied by other vehicles. A homography of the captured image is created. The homography is used to estimate an image of the parking area from an overhead viewpoint. A portion of the overhead image including the unoccupied parking space is displayed on a display screen within a passenger compartment of the vehicle.

8. An electronic parking-assistance arrangement for a vehicle, said arrangement comprising:
-
at least one of a forward-looking camera and a backward-looking camera provided in the vehicle; a processor coupled to the at least one camera, the processor being configured to; receive first images of a parking area, the images being captured by the camera from a substantially horizontal viewpoint; translate the first images into second images from a substantially vertical viewpoint; identify an unoccupied parking space within the second images; and superimpose a representation of the vehicle onto the second images when the vehicle is substantially adjacent to the unoccupied parking space, a position of the vehicle representation relative to the unoccupied parking space in the second images being continuously updated to indicate an actual position of the vehicle relative to the unoccupied parking space; and a display screen provided in a passenger compartment of the vehicle and coupled to the processor, the display screen being configured to receive and display the second images with the superimposed representations of the vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of displaying map information, comprising the steps of:
-
providing a vehicle with at least one of a forward-looking camera and a backward-looking camera; using the camera to capture images of a surrounding area; creating homographies of the captured images; using the homographies to estimate images of the area from an overhead viewpoint; determining positions of the vehicle relative to the overhead images as the vehicle moves; and displaying the overhead images on a display screen within a passenger compartment of the vehicle, the displayed overhead images including real time representations of the vehicle, positions of the vehicle representations within the overhead images being substantially continuously updated based on the determining step. - View Dependent Claims (16, 17, 18, 19, 20)
