本文經由文獻探討與分析無線訊號、影像視覺與可見光通訊等技術在室內定位技術上之發展與應用。並對室內定位技術之瓶頸與場域應用會遭遇之挑戰進行深入剖析，對於日後如何設計更精確與低成本之室內定位系統之發展方向本論文亦將提出建言，有利於室內定位之普及與實際應用。

This paper explores and analyzes the developments and applications of wireless LAN, image vision methodology, and visible light communication technology in indoor positioning system through the literatures survey. And the development bottleneck and the challenges to the field applications for indoor positioning technology will be discussed in-depth. We will propose the suggestions and development direction of how to design the precise and low-cost indoor positioning system in the future. Hopefully this paper will be helpful for popularity and practical applications in indoor positioning.
