COMBINED BEACON AND SCENE NAVIGATION SYSTEM
First Claim
Patent Images
1. A controller for navigation in a navigation system, the controller comprising:
- an image sensor configured to generate an image within a field of view of the controller; and
navigation processing logic coupled to the image sensor, the navigation processing logic configured to process the image to alternatively implement beacon-based navigation and scene-based navigation depending on the processed image.

Abstract
A controller and navigation system to implement beacon-based navigation and scene-based navigation is described. The navigation system may generate position data for the controller to compensate for a misalignment of the controller relative to the coordinate system of the navigation system. The navigation system may also distinguish between a beacon light source and a non-beacon light source.

11. A method for controlling a navigation system, the method comprising:
-
generating a plurality of images within a field of view of an image sensor; determining whether at least one of the plurality of images includes a representation of a beacon; generating a first position data signal according to beacon-based navigation in association with an image which includes the representation of the beacon; and generating a second position data signal according to scene-based navigation in association with another image which excludes the representation of the beacon. - View Dependent Claims (12, 13, 14, 15)

16. A computer readable medium comprising machine readable instructions which, when processed by a digital processor of a navigation system, cause the digital processor to perform operations comprising:
-
receive a plurality of images within a field of view of an image sensor; determine whether at least one of the plurality of images includes a representation of a beacon; generate a first position data signal according to beacon-based navigation in association with an image which includes the representation of the beacon; and generate a second position data signal according to scene-based navigation in association with another image which excludes the representation of the beacon. - View Dependent Claims (17, 18, 19, 20)
