隨著包含室內導航系統、無人工廠、虛擬實境等應用的發展，高精確室
內定位技術受到廣大的關注。相關的精確度要求，可能造成潛在成本隨之增
加。基於商用上的實際考量，本論文將研究基於市面上較低成本的商用模組，
實現高精確室內定位的相關技術。
本論文利用商用投影機作為定位光源，相應投影機安裝於無線網路接取
節點，利用投影機精確調整光訊號投影角度的特性，進行終端用戶的位置掃
描，相應終端用戶收到相應光訊號時，會回傳相應反饋訊號，以提供接取節
點進行用戶估算。相關系統可與無線光通訊技術直接整合，提供定位之外的
通訊附加價值。為了測試使用低成本商用模組實現相關系統的可行性與相應
表現，本論文從基礎電子元件整合 Arduino Nano 控制開始，從頭建立相關概
念的原型系統，並進行包含各式投影機參數設定(像素大小、亮度、掃描方式)
設定、用戶數目、通訊方式等議題對於系統表現的深入討論。本論文成功透
過低成本的商用模組，驗證基於可見光通訊、具有 cm 等級定位精準度的定
位系統。

With the development of applications including indoor navigation systems,
unmanned factories, and virtual reality, high-accuracy indoor positioning
technology has attracted wide attention. The high accuracy requirements may
increase in potential costs. Based on practical considerations in commercial
utilization, this thesis will study related technologies for achieving high-precision
indoor positioning based on relatively low-cost commercial modules on the market.
This thesis uses a commercial projector as a positioning optical source, and
the projector is also installed as a wireless network access node. Using the
projector characteristics of precisely adjusting the projection angle of the optical
signal, the user position is being scanned. When the user receives the optical signal
from the projector, the user will send a corresponding signal back to provide the
access node for estimating where is the user. To test the feasibility and
corresponding performance of using low-cost commercial modules for positioning
systems, this thesis study in the integration of basic electronic components with
Arduino Nano, builds a module and sets various projector parameters (pixel size,
brightness, scanning mode) setting, number of users, communication mode and
other topics for discussion of the system performance. Finally, this thesis
successfully verified a positioning system based on visible light communication
with centimeter-level positioning accuracy through low-cost commercial modules
