Blind spot image display apparatus and method thereof for vehicle
First Claim
1. A blind spot image display apparatus for a vehicle, which displays an image of a blind spot area to which a driver'"'"'s view is obstructed by a structural component of the vehicle, the apparatus comprising:
- an image displaying device provided on the structural component of the vehicle;
an imaging device configured to take an image of a peripheral area of the vehicle, the peripheral area including at least the blind spot area; and
an image converting device configured to convert the image taken by the imaging device, and to create an output image to be displayed on the image displaying device, based on space coordinates of a reference point at which the driver'"'"'s eye point is assumed to exist and space coordinates of each of pixels constituting a display screen of the image displaying device, wherein the image converting device sets a spherical reference surface defined as a surface of a sphere around the reference point, in a predetermined position in the peripheral area of the vehicle including the blind spot area, the image converting device obtains positions respectively of intersecting points at which half-lines extending from the reference point as a start point and passing respectively through the pixels constituting the display screen of the image displaying device, intersect with the spherical reference surface, the image converting device identifies pixels of the image taken by the imaging device corresponding to the respective intersecting points, based on parameters of the imaging device, and the image converting device creates the output image to be displayed on the image displaying device by using data of the respective identified pixels of the taken image.

Abstract
An apparatus for displaying an image of a blind spot area to which driver'"'"'s view is obstructed by a pillar, includes: an monitor on the pillar; a camera to take an image of a peripheral area including the blind spot area; and an image converting device to convert the camera image and create an output image to be displayed on the monitor. The image converting device sets in the peripheral area a reference surface defined as a surface of a sphere around a reference point at which the driver'"'"'s eye point is assumed to exist; obtains positions of intersecting points at which half-lines extending from the reference point and passing through respective screen pixels of the monitor intersect with the reference surface; identifies pixels of the camera image corresponding to the respective intersecting points based on the camera'"'"'s parameters; and creates the output image using data of the identified pixels.

1. A blind spot image display apparatus for a vehicle, which displays an image of a blind spot area to which a driver'"'"'s view is obstructed by a structural component of the vehicle, the apparatus comprising:
-
an image displaying device provided on the structural component of the vehicle;
an imaging device configured to take an image of a peripheral area of the vehicle, the peripheral area including at least the blind spot area; and
an image converting device configured to convert the image taken by the imaging device, and to create an output image to be displayed on the image displaying device, based on space coordinates of a reference point at which the driver'"'"'s eye point is assumed to exist and space coordinates of each of pixels constituting a display screen of the image displaying device, wherein the image converting device sets a spherical reference surface defined as a surface of a sphere around the reference point, in a predetermined position in the peripheral area of the vehicle including the blind spot area, the image converting device obtains positions respectively of intersecting points at which half-lines extending from the reference point as a start point and passing respectively through the pixels constituting the display screen of the image displaying device, intersect with the spherical reference surface, the image converting device identifies pixels of the image taken by the imaging device corresponding to the respective intersecting points, based on parameters of the imaging device, and the image converting device creates the output image to be displayed on the image displaying device by using data of the respective identified pixels of the taken image. - View Dependent Claims (2, 3)

4. A method of displaying an image of a blind spot for a vehicle, the blind spot area being an area to which a driver'"'"'s view is obstructed by a structural component of the vehicle, the method comprising the steps of:
-
providing an image displaying device on the structural component of the vehicle;
providing a imaging device configured to take an image of a peripheral area of the vehicle, the peripheral area including at least the blind spot area; and
converting the image taken by the imaging device to create an output image to be displayed on the image displaying device, based on space coordinates of a reference point at which the driver'"'"'s eye point is assumed to exist and space coordinates of each of pixels constituting a display screen of the image displaying device, wherein, in the step of converting the image, a spherical reference surface defined as a surface of a sphere around the reference point is set in a predetermined position in the peripheral area of the vehicle including the blind spot area, positions respectively of intersecting points at which half-lines extending from the reference point as a start point and passing respectively through the pixels constituting the display screen of the image displaying device, intersect with the spherical reference surface are obtained, pixels of the image taken by the imaging device corresponding to the respective intersecting points, are identified based on parameters of the imaging device, and the output image to be displayed on the image displaying device is created by using data of the respective identified pixels of the taken image.
