PARKING ASSISTANCE SYSTEM
First Claim
1. A parking assistance system comprising:
- a first overhead view video generation section that generates, based on camera videos shot by a plurality of cameras mounted to a vehicle, a first overhead view video virtually overlooking, from above the vehicle, conditions surrounding the vehicle with the vehicle located at a center therein;
a parking target position detection section that detects a parking target position for parking the vehicle from the first overhead view video;
a viewpoint position determination section that determines a viewpoint position based on a positional relationship between the parking target position detected by the parking target position detection section and a vehicle position in the first overhead view video;
a rotation amount determination section that determines a rotation amount in the first overhead view video based on the positional relationship between the parking target position and vehicle position in the first overhead view video;
a viewpoint conversion table creation section that creates a viewpoint conversion table for moving a center position of the first overhead view video to the viewpoint position determined by the viewpoint position determination section and rotating the first overhead view video with respect to the viewpoint position as a rotation center by the rotation amount determined by the rotation amount determination section; and
a second overhead view video generation section that applies video conversion processing to the first overhead view video based on the viewpoint conversion table created by the viewpoint conversion table creation section to generate a second overhead view video in which the viewpoint position is located at a center thereof and which is obtained by rotating the first overhead view video by the rotation amount determined by the rotation amount determination section and outputs the second overhead view video to a display section.

Abstract
It is an object of the present invention to provide in real time, to a user, an overhead view video in which a parking space is displayed on a display screen, even if a vehicle is moved. A parking assistance system (1) includes a parking target position detection section (34) that detects a parking target position for parking the vehicle from a first overhead view video; a viewpoint position determination section (34) that determines a viewpoint position; a rotation amount determination section (34) that determines a rotation amount; a viewpoint conversion table creation section (35) that creates a viewpoint conversion table for rotating the first overhead view video on the basis of the viewpoint position and the rotation amount; and a second overhead view video generation section (36) that generates a second overhead view video from the first overhead view video on the basis of the viewpoint conversion table.
