Location based brand detection

Abstract

Techniques for determining brand information and refining a position of a mobile device are described herein. An example of a method for displaying branding information on a mobile device includes receiving a reference image feature data table based on a rough location of the mobile device, such that the reference image feature data table includes a collection of entity records and wherein each entity record includes a plurality of logo image feature fields, obtaining an image including a displayed logo, utilizing an image recognition process and the reference image feature data table on the image to determine a recognized logo, and displaying brand information based on the recognized logo.

What is claimed is: 
     
         1 . A method of providing reference image feature data to a mobile device, comprising:
 obtaining a rough location area of the mobile device;   selecting a relevant points of interest list based on the rough location area of the mobile device;   refining the rough location area of the mobile device if the relevant points of interest list is greater than a threshold;   building a reference image feature data table if the relevant points of interest list is less than or equal to the threshold; and   providing the reference image feature data table to the mobile device.   
     
     
         2 . The method of  claim 1  wherein the reference image feature data table includes at least one entity and a plurality of logo image feature fields that are associated with the entity. 
     
     
         3 . The method of  claim 2  wherein the reference image feature data table includes position information associated with each logo image feature. 
     
     
         4 . The method of  claim 1  wherein refining the rough location area includes receiving a wireless signal information from the mobile device. 
     
     
         5 . The method of  claim 4  wherein the wireless signal information includes Round Trip Time (RTT) data. 
     
     
         6 . An apparatus, comprising:
 a memory;   at least one processor coupled to the memory and configured to:
 obtain a rough location area of a mobile device; 
 select a relevant points of interest list based on the rough location area of the mobile device; 
 refine the rough location area of the mobile device if the relevant points of interest list is greater than a threshold; 
 build a reference image feature data table if the relevant points of interest list is less than or equal to the threshold; and 
 provide the reference image feature data table to the mobile device. 
   
     
     
         7 . The apparatus of  claim 6  wherein the reference image feature data table includes at least one entity and a plurality of logo image features that are associated with the entity. 
     
     
         8 . The apparatus of  claim 7  wherein the reference image feature data table includes position information associated with each logo image feature. 
     
     
         9 . The apparatus of  claim 6  wherein the at least one processor is further configured to receive a wireless signal information from the mobile device. 
     
     
         10 . The apparatus of  claim 9  wherein the wireless signal information includes Round Trip Time (RTT) data. 
     
     
         11 . An apparatus for providing reference image feature data to a mobile device, comprising:
 means for obtaining a rough location area of the mobile device;   means for selecting a relevant points of interest list based on the rough location area of the mobile device;   means for refining the rough location area of the mobile device if the relevant points of interest list is greater than a threshold;   means for building a reference image feature data table if the relevant points of interest list is less than or equal to the threshold; and   means for providing the reference image feature data table to the mobile device.   
     
     
         12 . The apparatus of  claim 11  wherein the reference image feature data table includes at least one entity and a plurality of logo image features that are associated with the entity. 
     
     
         13 . The apparatus of  claim 12  wherein the reference image feature data table includes position information associated with each logo image feature. 
     
     
         14 . The apparatus of  claim 11  wherein the means for refining the rough location area includes means for receiving a wireless signal information from the mobile device. 
     
     
         15 . The apparatus of  claim 14  wherein the wireless signal information includes Round Trip Time (RTT) data.
