Witryna2024. TLDR. An online map matching algorithm based on higher-order hidden Markov model (HMM) is proposed for processing trajectory data in complex urban road network environment such as parallel road segments and various road intersections and outperforms state-of-the-art algorithms built on the first-order HMM. PDF. WitrynaThird, fuzzy logic Map Matching (MM) is introduced to be integrated into the system. When there is GNSS outage, the INS/ Stereo VO solution can be projected on the digital map by fuzzy logic MM. The projected point provides the position information for the system, which effectively limits the drift of DR systems.
