Vision system as an aid to car navigation

Abstract

We focus on car navigation method using vision system and digital road map. Vision system installed onboard the car serves as an additional source of navigation information. It is used to determine the car lateral deviation relative to the road axial line, range and bearing to the intersection center. Algorithm generating these parameters is described with account for the topology and parameters of roads presented in the digital map. Accuracy of lateral deviation and range measurements is estimated using real data.
