Lane-Level Positioning Method for 3D In-Vehicle Navigation System

Abstract:

The objective of this study is to find an effective way to realize lane-level route guidance for vehicle navigation system. Based on the modeling of 3D map, a lane-level positioning method was presented by the way of combination of virtual differential GPS, height aiding, and collision detecting technique. GPS parameters were amended through virtual differential technology and height aiding technology by the way of elevation interpolation and least squares estimation in order to improve the output precision. Then a method of lane-level map matching was implemented in 3D digital map based on the collision detection technology. Tested by RTK technique, the method was proven to fulfill the demands of vehicle navigation systems.
