Method of updating navigation map data
First Claim
1. A method of updating navigation map data comprised in a global positioning system (GPS) navigator having a digital camera module on real time, the method comprising:
- receiving at least one GPS signal to obtain at least one corresponding coordinate position with movement of the global positioning system navigator;
taking at least one image of road scene when traveling to a street intersection is confirmed, and recording the coordinate position of the street intersection;
recording a traveling route comprising the image according to the coordinate positions received before traveling to a next street intersection; and
updating the map database according to the traveling route when the traveling route does not exist in the map database.

Abstract
A method of updating navigation map data obtains at least one corresponding coordinate position with movement of the global positioning system navigator by receiving at least one satellite positioning signal. When it is determined that a vehicle is traveling to a street intersection, at least one image of road scene is photoed, and the coordinate position of the street intersection is recorded. At the same time, a traveling route comprising the image is recorded according to all coordination positions received between intersections, and a street map, road type information, and road scene information in a map database are updated according to the traveling route, such that navigation map database is updated, navigation route accuracy is maintained, and scene navigation and other functions are implemented immediately without linking to a server.
