摘要
A method of using road signs to augment Global Positioning System (GPS) coordinate data for calculating a current position of a personal navigation device includes obtaining recent GPS coordinate data with the personal navigation device, obtaining an image from a camera of the personal navigation device, the image showing areas surrounding a road on which the personal navigation device is traveling, recognizing a sign in the image by performing image processing on the image, and using a known position of the sign to augment the recent GPS coordinate data in order to more precisely determine an actual location of the personal navigation device.
