1. A method for assisting in vehicle parking, 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 an image of a parking area including at least one unoccupied parking space and a plurality of parking spaces occupied by other vehicles;
creating a homography of the captured image;
using the homography to estimate an image of the parking area from an overhead viewpoint;
displaying a portion of the overhead image including the unoccupied parking space on a display screen within a passenger compartment of the vehicle;
measuring a size of the unoccupied parking space, the measuring being performed on the captured image and/or the overhead image; and
providing an indication to a user of a success rate of previous parallel parking attempts in unoccupied parking spaces having sizes substantially equal to the measured size.

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.

10. 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; 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; measure a size of the unoccupied parking space, the measuring being performed on the first images and/or the second images; and provide an indication to a user of a success rate of previous parallel parking attempts in unoccupied parking spaces having sizes substantially equal to the measured size; 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 (11, 12, 13, 14, 15, 16)

17. 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 parking area including at least one unoccupied parking space and a plurality of parking spaces occupied by other vehicles; creating homographies of the captured images; using the homographies to estimate images of the parking area from an overhead viewpoint; determining positions of the vehicle relative to the overhead images as the vehicle moves; 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; measuring a size of the unoccupied parking space, the measuring being performed on the captured images and/or the overhead images; and providing an indication to a user of a success rate of previous parallel parking attempts in unoccupied parking spaces having sizes substantially equal to the measured size. - View Dependent Claims (18, 19, 20, 21)
