Dynamic position calibration by road structure detection

Abstract

In this research study, the potential of landmarks for accuracy improvement in terms of satellite-based localization is analyzed. Advanced driver assistance systems (ADAS) and vehicle-to-vehicle (V2V) communication applications benefit from precise determination of position. Especially applications for cooperative car safety work best when the position determination is as accurate as possible. The novel approach is related to the differential GPS method, but without using a base station. Previously measured landmarks are used instead. To determine the potential of the approach, the level of increasing localization accuracy is evaluated. Moreover the distribution of naturally existing landmarks is analyzed using the recorded data of an endurance testing vehicle.
