中文摘要 | 本文提出整合Wi-Fi與GPS(Wi-Fi/GPS)技術於室外定位的演算法,希望在都市區域能提供無縫的適地性服務。以國立政治大學的山下校區為實驗區,並對下列議題加以研究:(1)Wi-Fi定位的精度,(2)GPS定位的精度,(3)Wi-Fi/GPS定位的精度,及(4)Wi-Fi定位之平面精度與參考點間距之函數關係。根據實驗結果顯示:(1)Wi-Fi/GPS室外定位的平面與高程精度,皆優於Wi-Fi定位或GPS定位;(2)可以簡單函數,建立Wi-Fi定位之平面精度與參考點間距之關係。 |
英文摘要 | In order to provide a ubiquitous location-based service (LBS) in the urban areas, an outdoor positioning algorithm integrating Wi-Fi with Global Positioning System (GPS) (Wi-Fi/GPS) was proposed in this study. Two test data sets from the downhill campus of National Chengchi University were used to test the proposed algorithm. The following topics were studied: (1) Wi-Fi positioning accuracy, (2) GPS positioning accuracy, (3) Wi-Fi/GPS positioning accuracy, and (4) the relationship between the reference point intervals and the Wi-Fi planimetric accuracies. According to the test results, the following comments can be concluded: (1) the Wi-Fi/GPS positioning accuracies are better than those from Wi-Fi positioning or GPS positioning, and (2) a simple function can be used to establish the relationship between the reference point intervals and the Wi-Fi planimetric accuracies. |
