US 2009/0276153 A1 · Navigating method and navigation apparatus using road image identification

Abstract

A navigating method and a navigation apparatus capable of real-time road image identification are disclosed. The apparatus equips a camera used to capture the road image in some specific sections, and the image is used to be identified, so that the navigation accuracy can be improved. The preferred embodiment of the navigating method includes the steps of determining a section to be identified, and capturing the road image by means the camera installed in a vehicle, and retrieving the digitized road image which is used to compare the road image from an image database synchronously, and identifying the road, and transferring the identification result to a navigation system for producing the navigation information via vocal or a displayer.
