Vehicle-use visual field assistance system in which information dispatch apparatus transmits images of blind spots to vehicles
First Claim
1. A vehicle-use visual field assistance system comprising:
- an information dispatch apparatus comprisingblind spot image acquisition means configured to acquire a blind-spot image showing a current condition of a region that is a blind spot with respect to the forward field of view of a driver of an object vehicle approaching the vicinity of a street intersection,vehicle information receiving means configured to receive vehicle information, said vehicle information including a forward-view image corresponding to said forward field of view of said driver,image generating means configured to execute viewpoint conversion of said forward-view image and of said blind-spot image to a converted forward-view image and to a converted blind-spot image respectively, said converted forward-view image and converted blind-spot image having a common viewpoint, and to combine said converted forward-view image and converted blind-spot image into a synthesized image, andinformation dispatch means configured to transmit said synthesized image; and
a vehicle-mounted apparatus installed in said object vehicle, comprisinginformation receiving means configured to receive said synthesized image transmitted from said information dispatch apparatus,information transmitting means configured to transmit vehicle information relating to said object vehicle, andinformation display means configured to display said received synthesized image.

Abstract
A camera of a ground-based information dispatch apparatus captures a blind-spot image, showing a region that is a blind spot with respect to a vehicle driver. A vehicle-mounted camera captures a forward-view image corresponding to the viewpoint of the driver, and the forward-view image is transmitted to the information dispatch apparatus together with vehicle position and direction information and camera parameters. Based on the received information, the blind-spot image is converted to a corresponding image having the viewpoint of the vehicle driver, and the forward-view image and viewpoint-converted blind-spot image are combined to form a synthesized image, which is transmitted to the vehicle.

23. A vehicle-use visual field assistance system comprising:
-
an information dispatch apparatus comprising a first camera, installed at a location in or adjacent to a street intersection, said camera being positioned and oriented to capture a blind-spot image showing a current condition of a region that is a blind spot with respect to the forward field of view of a driver of an object vehicle approaching the vicinity of said street intersection, circuitry configured to generate first characteristic information, said first characteristic information being specific to said first camera and comprising internal parameters of said first camera, a location of said first camera, and a height and an orientation direction of said first camera; a radio receiver apparatus for receiving vehicle information relating to said object vehicle, said vehicle information including a forward-view image and second characteristic information, image generating means configured to convert said blind-spot image to a converted blind-spot image which has a viewpoint of said forward-view image, said conversion being executed based upon said first characteristic information and said second characteristic information, and to combine said forward-view image and at least a selected part of said converted blind-spot image into a synthesized image, and a radio transmitter for transmitting said synthesized image; and a vehicle-mounted apparatus installed in said object vehicle, comprising a second camera, mounted on said vehicle, for capturing said forward-view image, position detection means configured to detect a current location of said object vehicle, circuitry configured to generate second characteristic information, said second characteristic information being specific to said second camera and comprising internal parameters of said second camera, said current location, and a height and a current orientation direction of said second camera, a radio transmitter for transmitting said forward-view image in conjunction with said second characteristic information, as said vehicle information, a radio receiver for receiving said synthesized image transmitted from said information dispatch apparatus, and a display unit for displaying said received synthesized image. - View Dependent Claims (24)
