Abstract

A method for inspecting connectors of multi-fiber optical cables is disclosed. The method may include receiving a plurality of images of a plurality of areas of a connector and determining, via at least a processor, matching features in two or more images according to unique visual characteristics of the images. The method further may include aligning the images, according to unique matching features of the images, and combining the images such as to obtain a combined-image of the full connector or a desired area of the connector. The combined-image of the connector may be displayed on a monitor or a display.

First claim

What is claimed:

1. An apparatus for inspecting connectors of multi-fiber optical cables, the apparatus comprising a non-transitory computer readable media comprising a program configured to:
determine, via at least a processor, matching features in two or more images;
incrementally combine the images such as to obtain a combined-image of a connector; and
determine whether the combined-image is a full image of the connector by analyzing the connector in the combined-image, wherein the combined-image comprises a first image extended from an edge of a second image, wherein incrementally combining the images continues when the image is determined to not be a full image of the connector, and wherein incrementally combining the images stops when the image is determined to be a full image of the connector.

2. The apparatus of claim 1 , further comprising a camera configured to record a plurality of images of a plurality of areas of a connector.

3. The apparatus of claim 1 , further comprising a display for displaying the images and the combined-image.

4. The apparatus of claim 1 , wherein the program is configured to:
receive “live” streams of images;
automatically and “live” combine the stream of images in a combined-image of the connector; and
cause a display to display the combined-image “live”.

5. The apparatus of claim 4 , further comprising a program configured to determine whether the combined-image, obtained at a certain time during receiving the “live” stream, is the full image of the connector.

6. The apparatus of claim 5 , further comprising a program configured to cause a display to display the full image of the connector and to notify a user that the full image of the connector is displayed.

7. The apparatus of claim 1 , wherein the camera comprises a video-camera and one or more of the images are frames of a video-recording.

8. The apparatus of claim 1 , further comprising:
storage media for storing the plurality of images;
wherein the apparatus is configured to receive input from a user causing the apparatus to select a set of images, to match and align images of the set of images according to common features, and to combine the images in the combined-image.

9. The apparatus of claim 1 , wherein the program configured to determine matching features comprises an image recognition software.

10. A method for inspecting connectors of multi-fiber optical cables, the method comprising:
receiving a plurality of images of a plurality of areas of a connector;
determining, via at least a processor, matching features in two or more images and incrementally combining the images such as to obtain a combined-image of the connector;
causing a display to display the combined-image; and
determining whether the combined-image is a full image of the connector by analyzing the connector in the combined-image, wherein
the combined-image comprises a first image extended from an edge of a second image, wherein incrementally combining the images continues when the image is determined to not be a full image of the connector, and wherein incrementally combining the images stops when the image is determined to be a full image of the connector.

11. The method of claim 10 , wherein the recording is performed by a camera comprising a video-camera and wherein one or more of the plurality of images are frames of a video-recording.

12. The method of claim 10 , wherein the recording is performed by a camera comprising a still-camera and wherein one or more of the plurality of images are collected by the still-camera.

13. The method of claim 10 , further comprising:
receiving “live” streams of images from a camera, combining the stream images automatically and “live” in a combined-image, and causing a display to display the combined image “live”.

14. The method of claim 13 , further comprising:
determining whether the combined-image, obtained at a certain time during receiving the “live” stream, is the full image of the connector.

15. The method of claim 14 , further comprising:
displaying the full image of the connector; and
notifying a user that the full image of the connector has been displayed.

16. The method of claim 10 , further comprising:
storing the plurality of images as still-images and as frames of video-recordings;
receiving input from a user to select a set of images, to align the selected images and to combine the selected images in a combined-image.

17. The apparatus of claim 1 , wherein the combined-image further comprises the first image extended away from the second image such that the combined image has a greater length than any of the first image and the second image.

18. The apparatus of claim 1 , wherein the combined-image further comprises a combination of a series of images, in addition to the two or more images, and
the images, of the series of images, extend from each other and from the two or more images.

19. The apparatus of claim 18 , wherein adjacent images, of the series of images, are aligned with each other at matching features contained within each adjacent image respectively.

20. The apparatus of claim 1 , wherein the combined-image further comprises a plurality of images extended from both the first image and the second image.

21. The method of claim 10 , wherein each of the two or more images comprises at least two fibers of a multi-fiber optical cable, and each image is of a respective area of the connector.

22. The method of claim 10 , further comprising determining whether the combined-image is the full image of the connector by analyzing a number of images combined into the combined-image.

23. The method of claim 10 , wherein the full image of the connector comprises a cross-sectional view comprising all fibers of a multi-fiber optical cable connected to the connector.
