BLIND SPOT DISPLAY APPARATUS
First Claim
1. A blind spot display apparatus that displays an image of an object in a blind spot of a vehicle, said apparatus comprising:
- a storage unit configured to store omni-directional images which have been obtained from cameras at different positions and each of which includes the image of the object in the blind spot and an image of the vehicle;
an object model generating unit configured to calculate a coordinate position of the object seen from a predetermined camera among the cameras, using a difference between coordinate positions of the images of the object that are included in the omni-directional images;
a vehicle model generating unit configured to calculate a coordinate position of the vehicle seen from the predetermined camera, using a difference between coordinate positions of the images of the vehicle that are included in the omni-directional images; and
a display unit configured to display the image of the object as seen from the vehicle on a display, using the calculated coordinate positions of the object and of the vehicle, the image of the object being included in common in each of the omni-directional images.

Abstract
Provided is a blind spot display apparatus that presents a situation at a blind spot occurring at an intersection from a driver'"'"'s viewpoint, in a method of presenting the situation to a driver. For generating a blind spot situation image without any uncomfortable feeling, the driver'"'"'s viewpoint and a depth of the blind spot are calculated with higher precision and lower cost. The blind spot display apparatus includes: an omni-directional image storage unit (102) storing omni-directional images obtained at different positions; a blind spot model generating unit (109) calculating a position of the object based on each image of the object (in the blind spot) included in the omni-directional images; an own-vehicle model generating unit (110) calculating a position of a vehicle based on images of the vehicle included in the omni-directional images; an own-vehicle viewpoint coordinate transforming unit (107) transforming the calculated position of the object into display coordinates relative to the calculated position of the vehicle; and a display unit (108) that performs display.

18. A blind spot display method of displaying an image of an object in a blind spot of a vehicle, said method comprising:
-
storing omni-directional images which have been obtained from cameras at different positions and each of which includes the image of the object in the blind spot and an image of the vehicle; calculating a coordinate position of the object seen from a predetermined camera among the cameras, using a difference between coordinate positions of the images of the object that are included in the omni-directional images; calculating a coordinate position of the vehicle seen from the predetermined camera, using a difference between coordinate positions of the images of the vehicle that are included in the omni-directional images; and displaying the image of the object as seen from the vehicle on a display, using the calculated coordinate positions of the object and of the vehicle, the image of the object being included in common in each of the omni-directional images.

19. A computer program for displaying an image of an object in a blind spot of a vehicle using a computer, said computer program being recorded on a computer-readable recording medium and causing the computer to execute:
-
storing omni-directional images which have been obtained from cameras at different positions and each of which includes the image of the object in the blind spot and an image of the vehicle; calculating a coordinate position of the object seen from a predetermined camera among the cameras, using a difference between coordinate positions of the images of the object that are included in the omni-directional images; calculating a coordinate position of the vehicle seen from the predetermined camera, using a difference between coordinate positions of the images of the vehicle that are included in the omni-directional images; and displaying the image of the object as seen from the vehicle on a display, using the calculated coordinate positions of the object and of the vehicle, the image of the object being included in common in each of the omni-directional images. - View Dependent Claims (20)
