摘要:
Methods and systems for location determination and navigation using textual information may comprise in a wireless communication device: capturing one or more images of one or more sources of textual information in the vicinity of the wireless communication device, extracting text from the one or more sources of textual information, and determining a position of the wireless communication device by, at least in part, determining a distance to a letter at a beginning of the one or more sources of textual information, determining a distance to a letter at an end of the one or more sources of textual information, and triangulating the position using the determined distances. An orientation of the text in the captured one or more images may be sensed relative to the wireless device. An orientation of the wireless device may be utilized in conjunction with the extracted text for the position determining.
