技術名稱: 多感測器協同定位技術

技術簡介

傳統 GPS 定位技術提供室外位置資訊,但 GPS 於無法收到衛星訊號之室內環境即無法運作,另外,對於多樓層之高樓內亦無法提供高度資訊辨識使用者所在樓層。常見之室內定位技術包括 Wi-Fi 訊號定位與近年來熱門之 Apple iBeacon 訊號定位技術。然而,根據不同應用場域特性與成本考量等需求,單一技術之定位效果往往不及多技術整合後之準確。本技術透過結合多種無線訊號 (Wi-Fi、iBeacon 等) 以及慣性感測元件訊號 (加速度計、地磁感測器、陀螺儀等) 之融合,以三角定位與樣式比對演算法、結合如 Particle Filter 等訊號處理技術,提供一套相較於單一技術更加準確之定位系統。此外,本技術亦包含半自動化佈建工具,協助加速系統佈建之無線訊號訓練流程。

Abstract

GPS positioning system is widely used in vehicle navigation system. But it can’t be used in indoor navigation. Recently the wifi positioning system using hotspot detection method is used in mobile phone, the resolution is about 10m. The muti-sensors enabled positioning system integrates wifi signal strength detection and inertial navigation system which leverages the gyroscope, accelerometer and magnetic sensor. The technology integrates these two sub-systems to provide the indoor navigation solution.
