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.
Claims17
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.
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.
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.
