| Abstract(in English) | In this paper, considering a train positioning system using triaxial acceleration information and acoustic information obtained from smartphone fixed in the train by various performance evaluations. First, we study ground truth that become a problem in case of evaluation of the positioning system, and we calculate ground truth by using video data showing the outside of the train. Next, we mention that the triaxial acceleration information include different characteristics about location information when fixed in the train by examination about acquired triaxial acceleration information and acoustic information. The results of position estimation using a single piece of information among the four types of information show that lateral acceleration is the best performance among triaxial acceleration information and acoustic information. We scrutiny the input fusion method, the output fusion method, and the hybrid method are examined as three types of data fusion methods, and the results of the performance evaluation describes the hybrid method represent best performance under this research conditions. |
