Optimization of map matching algorithms for indoor navigation in shopping malls

Maps used in car navigation systems differ from indoor maps due to the fact that they were designed to address different needs. Therefore, map matching techniques used for outdoor navigation cannot be applied indoors without significant modifications. The main aim of this paper is to present modified map matching algorithm for special usage such as indoor navigation in shopping malls, hotels and airports. The research concentrates to improve accuracy of positioning engine and natural presentation of pedestrian trajectory. The article includes the indoor map matching algorithm proposals, with the highlights of their strengths and weaknesses.
