| Outline of Final Research Achievements |
The authors have developed a high-accurate positioning system for wide indoor area by using ultrasonic. Feature of the proposed system is that the system is not required time synchronization between transmission and receiving parts. The system evaluation was carried out in a corridor of more than 30m range, and the positioning error less than a few cm was verified. The positioning system by using a speaker of a smartphone has also developed, and its positioning accuracy is maintained even in the noisy environment.
The server system that displays the map and positioning information has been designed and implemented in order to visualize the positioning results in real time. The dead reckoning by using inertia sensors implemented in a smartphone has been investigated. The authors realize the positioning platform that can be corresponded to user’s accuracy requirement by combining the positioning system by ultrasonic and dead reckoning by inertia sensors.
