Evaluation of Pose Hypotheses by Image Feature Extraction for Vehicle Localization

Abstract. For the realization of driving assistance and safety systems vehicles are being increasingly equipped with sensors. As these sensors contribute a lot to the cost of the whole package and at the same time consume some space, car manufacturers try to integrate applications that make use of already integrated sensors. This leads to the fact that each sensor has to fulfil several functions at once and to deliver information to different applications. When estimating very precise positioning informa-tion of a vehicle existing sensors have to be combined in an appropriate way to avoid the integration of additional sensors into the vehicle. The GPS receiver, which is coupled with the navigation assistant of the vehicle, delivers a rough positioning information, which has to be im-proved using already available information from other built in sensors. The approach discussed in this paper uses a model-based method to com-pare building models obtained from maps with video image information. We will examine, if the explorative coupling of sensors can deliver an appropriate evaluation criteria for positioning hypotheses
