Parking assist method and parking assist apparatus
First Claim
1. A method of assisting a vehicle parking operation, comprising:
- acquiring image data from a camera unit installed in the vehicle;
storing the acquired image data in image storage means;
generating bird'"'"'s eye view data representing an image of a nearby area around a current vehicle position in the form of a bird'"'"'s-eye view based on the image data stored in the image data storage means when the vehicle parking operation is stopped; and
displaying the bird'"'"'s eye view with a vehicle mark indicating the current vehicle position superimposed on the bird'"'"'s eye view, on the display screen.

Abstract
A navigation apparatus includes a controller, an image data input unit adapted to acquire image data from a camera installed in a vehicle, and an image memory for storing the image data. The navigation apparatus also includes an image processing unit converting data extracted from the acquired image data to data simulating a virtual viewpoint. The image processing unit stores the converted data in the image memory in associated with position data indicating the position at which the image was taken by the camera. Using a plurality of sets of converted data, the image processing unit generates bird'"'"'s eye view data representing a bird'"'"'s-eye image of an area nearby the current vehicle position. When the controller determines that parking operation is stopped, the image processing unit displays the bird'"'"'s eye view image together with a mark indicating the current vehicle position.

24. A parking assist apparatus installed in a vehicle, comprising:
-
vehicle status determination means for determining whether a vehicle parking operation is stopped, based on vehicle information input to the vehicle status determination means;
image data acquisition means for acquiring image data from a camera unit installed in the vehicle;
first image processing means for generating converted data by image processing of the acquired image data;
image data storage means for storing the converted data;
composite data generation means for generating composite data including data representing an image of a rear end portion of the vehicle and an image of a nearby area behind the vehicle, based on current-position image data acquired at the current vehicle position and the converted data which is stored in the image data storage means and which represents an image of an area in a current blind spot of the camera unit;
second image processing means for generating, using the converted data stored in the image data storage means, bird'"'"'s eye view data which represents a bird'"'"'s-eye view image of an area completely surrounding the vehicle at the present position and which includes a smaller percentage of the current-position image data than is included in the composite data; and
moving body detection means for detecting a moving body in an area nearby the current vehicle position;
image output means for outputting, responsive to a determination that the vehicle parking operation is stopped, a bird'"'"'s eye view image including an image of the whole vehicle based on the bird'"'"'s eye view data and a vehicle mark indicating the current vehicle position superimposed on the bird'"'"'s eye view image, for display on a display screen; and
image switching means for switching image data, when the image based on the bird'"'"'s eye view data and the vehicle mark are displayed on the display screen, responsive to detection of a moving body, to output the composite data to the display screen.
