Abstract

A method for displaying and processing an image captured by an optical system used to simulate a rear-view system of a vehicle, includes capturing the image, identifying primary edges of a first image of the plurality of images, locating a first border within the first image that extends to part of a first edge of the first image, identifying secondary edges of a second image of the plurality of images, selecting a second edge from the secondary edges closest in position and orientation to the part of the first edge of the first image, locating a second border within the second image that extends to the second edge, and adjusting the second image such that a second part of the second border of the second image aligns with the first border of the first image, wherein the optical system simultaneously simulates both a plane mirror and a spotter mirror in form of a spherical mirror in the single image to provide a plurality of optical subsystems.

First claim

What is claimed is:

1. A method for producing a single image from data collected in a plurality of images captured by an optical system to simulate a mirror used as a rear-view mirror of a vehicle, the method comprising:
identifying primary edges of a first image of the plurality of images;
locating a first border within the first image that extends to part of a first edge of the first image;
identifying secondary edges of a second image of the plurality of images;
selecting a second edge from the secondary edges closest in position and orientation to the part of the first edge of the first image;
locating a second border within the second image that extends to the second edge; and
adjusting the second image such that a second part of the second border of the second image aligns with the first border of the first image,
wherein the optical system simultaneously simulates both a plane mirror and a spotter mirror in form of a spherical mirror in the single image to provide a plurality of optical subsystems.

2. The method of claim 1 , wherein the plurality of optical subsystems includes a system designed to detect electromagnetic radiation outside the visible spectrum.

3. The method of claim 1 , wherein identifying secondary edges includes identifying secondary edges of a second image of the plurality of images closest in position and orientation to at least part of the first edge of the first image.

4. The method of claim 1 , wherein the step of adjusting includes generating an overall image using the first and second images.

5. The method of claim 4 , further comprising:
rectifying visual distortion in the single image.

6. The method of claim 1 , wherein a portion of the secondary edges and a portion of the first edge overlap.

7. The method of claim 6 , wherein the portion of the first image includes a part of the secondary edges and the first edge.

8. The method of claim 1 , further comprising:
iteratively selecting first and second images until all of the plurality of images have been adjusted to produce the single image.

9. The method of claim 8 , wherein the step of adjusting includes a step of generating an overall image using the plurality of images.

10. The method of claim 9 , further comprising:
rectifying visual distortion in the single image.

11. The method of claim 1 , further comprising:
classifying an object by sampling a periodic descriptor function for a query point in the image from the environment.

12. The method of claim 11 , further comprising:
extracting at least one feature value from at least one of one or more keypoints in an image from an environment to assist in the step of classifying the object.

13. A method for producing a single image from data collected in a plurality of images captured by an optical system to simulate a mirror used as a rear-view mirror of a vehicle, the method comprising:
identifying primary edges of a first image of the plurality of images;
locating a first border within the first image that extends to part of a first edge of the first image;
identifying secondary edges of a second image of the plurality of images;
selecting a second edge from the secondary edges closest in position and orientation to the part of the first edge of the first image;
locating a second border within the second image that extends to the second edge;
adjusting the second image such that a second part of the second border of the second image aligns with the first border of the first image; and
stitching the first image and the second image together to form a single image,
wherein the optical system simultaneously simulates both a plane mirror and a spotter mirror in form of a spherical mirror in the single image to provide a plurality of optical subsystems.
