Methods and systems for augmented navigation
First Claim
1. A navigation device comprising:
- a processing device;
a memory communicatively coupled to said processing device, said memory comprising a database of cartographic navigation map data;
a first sensor operable to provide location data to said processing device;
a display operatively coupled to said processing device;
a gyroscope; and
at least one image acquisition device operatively coupled to said processing device, said processing device programmed to, when in a first mode of operation, to cause said display to display a portion of the cartographic navigation map data, the displayed portion based on the location data received by said processing device, and said processing device configured, when in a second mode of operation, to cause said display to display an image acquired by said at least one image acquisition device, the image overlaid by one or more symbols indicative of one or more points of interest within the database of cartographic navigation map data, the one or more symbols correlated to the acquired image based on the location data received by said processing device, said at least one image acquisition device being operable to provide a view angle and a focal length of a lens associated with said at least one image acquisition device to said processing device, said gyroscope being operable to determine which direction the lens of said at least one image acquisition device is directed, the directional information calculated by said processing device using received gyroscope data, and said processing device being programmed to correlate the view angle, focal length, and directional information with the map data in said database to assign a coordinate to each symbol on said display by calculating its relative position to an edge of the acquired image.

Abstract
A navigation device is described that includes a processing device, a memory communicatively coupled to the processing device, the memory including a database of cartographic navigation map data, a first sensor operable to provide location data to the processing device, a display operatively coupled to the processing device, and an image acquisition device operatively coupled to the processing device. The processing device is programmed to, when in a first mode of operation, to cause the display to display a portion of the cartographic navigation map data, the displayed portion based on the location data received by the processing device. The processing device is further configured, when in a second mode of operation, to cause the display to display an image acquired by the image acquisition device, the image overlaid by one or more symbols indicative of one or more points of interest within the database of cartographic navigation map data, the one or more symbols correlated to the acquired image based on the location data received by the processing device.

9. An augmented navigation method for a navigation device comprising:
-
determining if the navigation device is in a map display mode or in an acquired image display mode; if the navigation device is determined to be in a map display mode, determining a location of the navigation device, and displaying a portion of a cartographic map associated with the determined location; and if the navigation device is determined to be in an acquired image display mode, determining a location of the navigation device, providing a view angle and a focal length of a lens associated with an image acquisition device coupled to the navigation device, determining, using a gyroscope, which direction the lens of the image acquisition device is directed, correlating the view angle, focal length, and directional information with the cartographic map data, assigning a coordinate to each symbol on a display by calculating its relative position to an edge of an acquired image, displaying the acquired image, and displaying overlays of points of interest on the acquired image, the points of interest stored in the cartographic map data, the overlays correlated to be in a correct position with respect to the acquired image. - View Dependent Claims (10, 11, 12, 13)
