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;

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

selecting a prominent location along the travel route;

modifying the orientation location with the prominent location as the orientation location,

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

wherein;

selecting the prominent location includes selecting the prominent location based on a prominence score.

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

4. The method as claimed in claim 1 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 the 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;

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

wherein;

selecting the prominent location includes selecting the prominent location based on a prominence score.

7. 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.

8. 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.

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;

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.

10. 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;

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

a route modification module, coupled to the orientation module, for modifying the orientation location with the prominent location as the orientation location, the route modification module includes an instruction generation module for generating an orientation instruction from the origin location to the orientation location; and

wherein;

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

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

11. The system as claimed in claim 10:

the orientation module is for selecting the prominent location recognizable from the travel route.

12. The system as claimed in claim 10 wherein:

the orientation module is for selecting the prominent location along the travel route closest to the origin location.

13. The system as claimed in claim 10 wherein:

the route modification module is for generating an orientation instruction from the origin location to the orientation location; and

further comprising;

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

14. The system as claimed in claim 10 wherein:

the search module is for generating a search region with the origin location within the search region and for searching for a prominent location within the search region.

15. The system as claimed in claim 10 wherein the search module is for selecting the prominent location having a first prominent location, a second prominent location, and a third prominent location.

16. The system as claimed in claim 10 wherein the orientation module includes:

a location selection module for selecting the prominent location 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.

17. The system as claimed in claim 10 wherein the orientation module includes:

the search module for selecting the prominent location 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 location having the highest value of the prominence score.
