摘要： A system and method is provided for automatically recognizing building numbers (530) in street level images (320). In one aspect, a processor (210) selects a street level image (320) that is likely to be near an address (530) of interest. The processor (210) identifies those portions of the image that are visually similar to street numbers, and then extracts the numeric values (410) of the characters displayed in such portions. If an extracted value (720) corresponds with the building number of the address of interest (750) such as being substantially equal to the address of interest, the extracted value (820) and the image portion (850) are displayed to a human operator. The human operator confirms, by looking at the image portion (850), whether the image portion (850) appears to be a building number that matches the extracted value (820). If so, the processor (210) stores a value that associates that building number with the street level image (320).
