Abstract

A method of operation of a navigation system includes: calculating a travel route from an origin location to a destination location; and identifying an orientation location along the travel route for assisting in an initial orientation from the origin location for displaying on a device.

Claims

1. A method of operation of a navigation system comprising:

calculating a travel route from an origin location to a destination location; and

identifying an orientation location along the travel route for assisting in an initial orientation from the origin location for displaying on a device.

2. The method as claimed in claim 1 wherein identifying the orientation location includes selecting a prominent location that is recognizable from the travel route with the prominent location as the orientation location.

3. The method as claimed in claim 1 wherein identifying the orientation location includes selecting a prominent location along the travel route that is closest to the origin location with the prominent location as the orientation location.

4. The method as claimed in claim 1 wherein identifying the orientation location includes:

generating an orientation instruction from the origin location to the orientation location; and

displaying the orientation instruction on the device.

5. The method as claimed in claim 1 wherein identifying the orientation location includes:

generating a search region with the origin location within the search region; and

searching for a prominent location within the search region with the prominent location as the orientation location.

6. A method of operation of a navigation system comprising:

calculating a travel route from an origin location to a destination location;

identifying an orientation location along the travel route for assisting in an initial orientation from the origin location;

selecting a prominent location that is recognizable from the travel route with the prominent location as the orientation location; and

generating an orientation instruction from the origin location to the orientation location for displaying the orientation instruction on a device.

7. The method as claimed in claim 6 wherein selecting the prominent location includes selecting the prominent location based on a prominence score for selecting the prominent location as the orientation location.

8. The method as claimed in claim 6 wherein selecting the prominent location includes selecting prominent locations having a first prominent location, a second prominent location, and a third prominent location.

9. The method as claimed in claim 6 wherein identifying the orientation location includes:

selecting prominent locations having a first prominent location, a second prominent location, and a third prominent location;

generating a search region, with the origin location within a search boundary; and

searching for the first prominent location, the second prominent location, and the third prominent location within the search boundary.

10. The method as claimed in claim 6 wherein identifying the orientation location includes:

selecting prominent locations having a first prominent location, a second prominent location and a third prominent location;

ranking the first prominent location, the second prominent location and the third prominent location based on a prominence score; and

displaying the orientation location as the prominent locations having the highest value of the prominence score.

11. A navigation system comprising:

a location unit for determining an origin location;

a route generation module, coupled to the location unit, for calculating a travel route from the origin location to a destination location; and

an orientation module, coupled to the route generation module, for identifying an orientation location along the travel route for assisting in an initial orientation from the origin location for displaying on a device.

12. The system as claimed in claim 11 wherein:

the orientation module is for selecting a prominent location that is recognizable from the travel route; and

further comprising;

a route modification module, coupled to the orientation module, for modifying the orientation location with the prominent location as the orientation location.

13. The system as claimed in claim 11 wherein:

the orientation module is for selecting a prominent location along the travel route that is closest to the origin location; and

further comprising;

a route modification module, coupled to the orientation module, for modifying the orientation location with the prominent location as the orientation location.

14. The system as claimed in claim 11 further comprising:

a route modification module, coupled to the route modification module, for generating an orientation instruction from the origin location to the orientation location; and

a display interface, coupled to the route modification module, for displaying the orientation instruction on the device.

15. The system as claimed in claim 11 wherein:

the orientation module includes a search module for generating a search region with the origin location within the search region and for searching for a prominent location within the search region; and

further comprising;

a route modification module, coupled to the orientation module, for modifying the orientation location with the prominent location as the orientation location.

16. The system as claimed in claim 11 wherein:

the orientation module includes a search module for selecting a prominent location along the travel route; and

further comprising;

a route modification module, coupled to the orientation module, for modifying the orientation location with the prominent location as the orientation location and the route modification module includes;

an instruction generation module for generating an orientation instruction from the origin location to the orientation location.

17. The system as claimed in claim 16 wherein:

the orientation module is for selecting the prominent location based on a prominence score; and

the route modification module for selecting the prominent location as the orientation location.

18. The system as claimed in claim 16 wherein the orientation module includes a search module for selecting prominent locations having a first prominent location, a second prominent location, and a third prominent location.

19. The system as claimed in claim 16 wherein the orientation module includes:

a location selection module for selecting prominent locations having a first prominent location, a second prominent location, and a third prominent location;

a region generation module for generating a search region, with the origin location within a search boundary; and

a region search module for searching for the first prominent location, the second prominent location, and the third prominent location within the search boundary.

20. The system as claimed in claim 16 wherein the orientation module includes:

a search module for selecting prominent locations having a first prominent location, a second prominent location and a third prominent location;

a ranking module, coupled to the search module, for ranking the first prominent location, the second prominent location and the third prominent location based on a prominence score; and

wherein;

the route modification module is for displaying the orientation location as the prominent locations having the highest value of the prominence score.
