In order to solve the problems of those endoscopes discussed above, this paper presents a new beter endoscope examination system named Megnetic-Levitated Capsule Endoscope Control System and related experiments. The purpose of this paper to develop a confortable, convenient, and effective endoscope examination method. Megnetic-levitated capsule endoscope control system applies magnetic-levitated control theories and technologies. It performs capsule endoscope movement and position control by using magnetic force; moreover, it transmits the images captured by capsule's inner image capturing device to the monitor. The system also utilizes man-machine interface control technologies. It make doctors not only be able to operate capsule endoscope easily and well with man-machine interface devices like joystick, monitor, and monitoring software fram, but also perform endoscope examination clearly and effectively. In this paper, to begin with, we will introduce megnetic-levitated control theories and methods concerned with the system and also discuss image capture and processing researches and technologies. Then, we will explan how to apply the theories and technologies of magnetic-levitated control and image to the system. The construction, design concept, and hardware scheme of system will be described. Finally, we will illustrate the experiment system and equipment, and also analyze the results of experiment to verify the theories presented in this paper. Further, the performance and usability of whole system will be estimated, and the future research direction about megnetic-levitated capsule endoscope will be discussed.中文摘要………………………………………………………… Ⅰ Abstract………………………………………………………… Ⅱ 目錄……………………………………………………………… Ⅳ 圖表目錄………………………………………………………… Ⅶ 第一章 緒論……………………………………………………………1 1.1 研究動機與目的…………………………………………… 1 1.2 研究方法…………………………………………………… 3 1.3 論文架構介紹……………………………………………… 4 第二章 內視數位影像理論基礎………………………………………5 2.1 內視鏡發展及應用概況…………………………………… 5 2.2 數位影像處理系統說明…………………………………… 6 2.2.1 系統架構與作業流程……………………………… 7 2.2.2 數位影像模式……………………………………… 8 2.2.3 影像處理技術………………………………………12 2.3 影像擷取……………………………………………………15 2.3.1 鏡頭…………………………………………………16 2.3.2 影像感測器…………………………………………17 2.3.3 自動測光技術………………………………………21 第三章 磁浮理論應用說明………………………………………… 23 3.1 磁浮概敘……………………………………………………23 3.2 磁浮原理與運用……………………………………………24 3.3 磁力分析與計算……………………………………………29 3.3.1 磁極間磁力分析……………………………………29 3.3.2 磁路分析技巧………………………………………31 3.3.3 能量法之應用………………………………………34 3.4 人體導磁係數說明…………………………………………39 3.5 線圈設計……………………………………………………40 第四章 系統設計與架構規劃……………………………………… 45 4.1 系統架構設計介紹…………………………………………45 4.2 系統控制硬體架構…………………………………………45 4.2.1 體內攝影控制系統…………………………………47 4.2.2 外圍控制系統………………………………………49 4.3 系統控制軟體規劃…………………………………………62 4.3.1 主磁場磁通控制……………………………………63 4.3.2 主磁線圈升降及受測物之旋轉方位控制…………64 4.3.3 影像擷取控制與影像處理…………………………66 4.4 人機介面操作設計…………………………………………67 4.4.1 指令輸入操控裝置設計……………………………68 4.4.2 監控畫面設計規劃…………………………………70 第五章 實驗說明與分析…………………………………………… 73 5.1 概述…………………………………………………………73 5.2 實驗流程及設備架構………………………………………73 5.2.1 實驗設備架構說明…………………………………73 5.2.2 控制介面規劃說明…………………………………84 5.3 系統磁力量測分析…………………………………………86 5.4 影像擷取分析………………………………………………92 5.5 整體系統評估………………………………………………96 第六章 結論………………………………………………………… 98 6.1 總結…………………………………………………………98 6.2 未來研究方向與目標………………………………………99 參考文獻………………………………………………………………1012380591 bytesapplication/pdfen-US膠囊內視鏡Capsule Endoscope磁浮膠囊內視鏡控制系統研製Study and Implementation of Magnetic-Levitated Capsule Endoscope Control Systemthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/53412/1/ntu-93-R91921065-1.pdf
