Abstract

A system is disclosed for determining optical correction information of optical equipment. The system includes a camera system for capturing at least one camera image, a target, toward which the camera system is directed, a detection area between the camera system and the target for receiving the optical equipment including at least one lens, and a processing system with a searching routine for determining at least one center of the at least one lens based on the at least one camera image of the target via the optical equipment.

Claims (20)

1 . A system for determining optical correction information of optical equipment, wherein the optical correction information is not known a priori, said system comprising a camera system, a target, toward which the camera system is directed, a detection area between the camera system and the target for receiving the optical equipment including at least one lens, and a processing system with a searching routine for determining at least one center of the at least one lens based on a plurality of images of the target acquired by the camera system as the target is viewed through the optical equipment in the detection area.

2 . The system as claimed in claim 1 , wherein the detection area includes an optically transparent surface on which the optical equipment may be placed.

3 . The system as claimed in claim 1 , wherein the target is a known distance from the camera system.

4 . The system as claimed in claim 1 , wherein the system further includes a position sensor to facilitate determining a position of the optical equipment.

5 . The system as claimed in claim 1 , wherein the searching routine employs iterative analysis of different resolutions of patterns responsive to the plurality of images.

6 . The system as claimed in claim 1 , wherein the searching routine employs iterative analysis of target images at different locations responsive to the plurality of images.

7 . The system as claimed in claim 1 , wherein the target includes a repeating pattern.

8 . The system as claimed in claim 1 , wherein the target includes a dynamic pattern that is changeable.

9 . A method of determining optical correction information of optical equipment including at least one lens, wherein the optical correction information is not known a priori, said method comprising positioning the optical equipment in a detection area, the detection area located between a camera system and a target, capturing a plurality of images with the camera system, said plurality of images including an image of the target viewed through the optical equipment in the detection area, and determining at least one center of the lens using a searching routine based on the plurality of images of the target viewed through the optical equipment.

10 . The method of claim 9 , wherein the detection area includes an optically transparent surface on which the optical equipment may be placed.

11 . The method of claim 9 , wherein the target is a known distance from the camera system.

12 . The method of claim 9 , wherein the system further includes a position sensor to facilitate determining a position of the optical equipment.

13 . The method of claim 9 , wherein the searching routine employs iterative analysis of different resolutions of patterns responsive to the plurality of images.

14 . The method of claim 9 , wherein the searching routine employs iterative analysis of target images at different locations responsive to the plurality of images.

15 . The method of claim 9 , wherein the target includes a repeating pattern.

16 . The method of claim 9 , wherein the target includes a dynamic pattern that is changeable.

17 . A system for determining optical correction information of optical equipment, wherein the optical correction information is not known a priori, said system comprising a camera system for capturing at least one camera image for capturing successive images, a target, toward which the camera system is directed, a detection area between the camera system and the target for receiving the optical equipment including at least one lens, and a processing system with a searching routine for determining at least one center of the at least one lens based on the successive images of the target as viewed through the optical equipment.

18 . The system as claimed in claim 17 , wherein the detection area includes an optically transparent surface on which the optical equipment may be placed.

19 . The system as claimed in claim 17 , wherein the searching routine employs iterative analysis of different resolutions of patterns responsive to the successive images.

20 . The system as claimed in claim 17 , wherein the searching routine employs iterative analysis of target images at different locations responsive to the successive images.
