本論文主要建立一套3D空間定位系統，採用三個線性CCD來對空間中的紅外線LED點光源來進行感測。利用基本幾何特性，以三個線性獨立的平面交集為空間一點，來計算空間位置。在電路系統方面以嵌入式系統的設計方法，採用DSP來進行CCD的控制與影像處理，後端則用可程式邏輯IC與USB2.0介面來進行資料傳輸，將三台CCD所感測到的LED位置回傳PC，並在PC上進行空間位置計算。影像處理在程式中執行，可更換不同的演算法較具彈性。所有的電路具有高度可程式化的能力，可因應情況而做調整。系統可進行靜態位置量測與動態的動作捕捉，亦可撰寫不同功能的程式，用於其它自動化方面訊號擷取與處理之應用，為一低成本、多功能的光學量測系統。

　　The major purpose of the thesis is to establish a 3D position localizer. Three line scan cameras detect the infrared LED. The detected image points and the axes of their lens form three planes. The three planes meet at a point that is the location of the LED. In this study, we use the concept of embedded system for local computation to alleviate the loading of the main computer. A DSP chip controls the linear CCD and execute the image process. The data flow is controlled by CPLD and transferred to the PC by USB2.0 interface. The calculation of space point is executed in PC. All of the circuits are highly programmable to overcome different situation. This system can measure static space points as well as the motion points at 960Hz data rate. This electronic-optical system is versatile and low cost, in that it can be tailored for other automation usage just changing the software.
