Dynamic map synchronization

A computer-implemented method of providing location-specific information, comprising:

• receiving a query image of a physical map captured by a computing device;
• determining, for the physical map, first features represented in the query image;
• determining at least one annotation that is marked on the physical map represented in the query image;
• comparing the first features to second features for map information of a map application;
• determining matching map information for the query image based at least in part upon at least one first feature matching at least one second feature from the map information, the matching map information including geographic location information;
• determining a set of feature points corresponding to the at least one annotation;
• determining a geographic relationship between the set of feature points and the geographic location information;
• determining a set of navigation instructions based at least in part on the geographic relationship;
• and
• based at least in part upon a current location of the computing device and the set of navigation instructions, displaying location-specific information on the computing device the location-specific information being related to at least one location in the query image.

A system for providing location-specific information, comprising:

• a processor;
• and
• a memory device including instructions that, when executed by the processor, cause the processor to:
• receive a query image of a physical map captured by a computing device;
• determine, for the physical map, first features represented in the query image;
• determine at least one annotation that is marked on the physical map represented in the query image:
• compare the first features to second features for map information of a map application;
• determine matching map information for the query image based at least in part upon at least one first feature matching at least one second feature from the map information, the matching map information including geographic location information;
• determine a set of feature points corresponding to the at least one annotation;
• determine a geographic relationship between the set of feature points and the geographic location information;
• determine a set of navigation instructions based at least in part on the geographic relationship;
• and
• based at least in part upon a current location of the computing device and the set of navigation instructions, display location-specific information on the computing device the location-specific information being related to at least one location in the query image.

A computer-readable storage medium storing instructions for providing location-specific information, the instructions when executed by a processor causing the processor to:

• receive a query image of a physical map captured by a computing device;
• determine, for the physical map, first features represented in the query image;
• determine at least one annotation that is marked on the physical map represented in the query image:
• compare the first features to second features for map information of a map application;
• determine matching map information for the query image based at least in part upon at least one first feature matching at least one second feature from the map information, the matching map information including geographic location information;
• determine a set of feature points corresponding to the at least one annotation;
• determine a geographic relationship between the set of feature points and the geographic location information;
• determine a set of navigation instructions based at least in part on the geographic relationship;
• and
• based at least in part upon a current location of the computing device and the set of navigation instructions, display location-specific information on the computing device the location-specific information being related to at least one location in the query image.
