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
a processor coupled to the image sensor, the processor configured to process the image to alternatively implement beacon-based navigation and scene-based navigation depending on the processed image,wherein the processor is further configured to determine if the processed image includes a representation of a beacon, to implement the beacon-based navigation in response to a determination that the processed image includes the representation of the beacon and to implement the scene-based navigation in response to a determination that the processed image excludes the representation of the beacon.

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.

2. A non-transitory computer readable medium comprising machine readable instructions which, when executed 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 in response to a determination that the image includes the representation of the beacon; and generate a second position data signal according to scene-based navigation in association with another image in response to a determination that the another image excludes the representation of the beacon. - View Dependent Claims (3, 4, 16, 17)

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 using the 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 in response to a determination that the image includes the representation of the beacon; and generating a second position data signal according to scene-based navigation in association with another image in response to a determination that the another image excludes the representation of the beacon wherein at least one of the determining, the generating the first position data signal and the generating the second position data is performed by a navigation processing logic in one of an integrated circuit and a processor of the navigation system. - View Dependent Claims (12, 13, 14, 15)
