Abstract

This invention provides an instantaneous method for a user or traveler to obtain a meaning of a symbol that is unfamiliar to said user. The symbol is captured in a format that is easily transmitted to a remote database server. Together with the symbol, the GPS coordinates of the location of the symbol must be sent to the server. The server performs an image matching search, and then uses the location information (GPS) to resolve multiple matches and to determine the meaning of the symbol and instantaneously transmits in the language of their choice the meaning to the user requesting the search.

Claims

1. A method for determining a meaning of traffic symbols, comprising:

capturing an image of a symbol using an imaging device selected from a group consisting essentially of a cell phone camera, digital camera, wi-fi camera, and scanner;

transmitting image data to an image database, the image data corresponding to the image of the symbol, and captured image location data, the location data comprising a geographical location of the imaging device

determining a meaning of the symbol based on the image data and the location data;

comparing the image data with symbol data, the symbol data being associated with location data, for determining whether the symbol data includes the captured symbol of the image data;

updating the symbol data to include the image data when the symbol data does not include the symbol image data before the updating; and

transmitting to a cell phone of a user of the imaging device the meaning of the symbol.

2. The method of claim 1, the image database being configured to store symbol data, the symbol data including at least one of a pictogram and an iso-symbol, and at least one meaning corresponding to the pictogram or the iso-symbol.

3. The method of claim 2, comprising the meaning being associated with a geographical location.

4. The method of claim 3, comprising:

searching the database for symbol data based on the location data.

5. The method of claim 1, the meaning being transmitted by voice transmission.

6. The method of claim 1, comprising:

identifying a symbol or meaning stored in the image database that corresponds to the symbol of the image data.

7. The method of claim 6, comprising:

transmitting to the user an indication that a corresponding symbol cannot be identified in the image database.

8. The method of claim 1, comprising:

cleaning up the captured image before the transmitting.

9. The method of claim 1, the captured image being in a digital data format.
