  • 本文主要的目的在於運用可轉向控制攝影機,發展一套海岸影像觀測與分析系統。利用一台具有Pan/Tilt控制功能之攝影機拍攝不同方位的影像,取代架設多台拍攝不同方向之攝影機,進行海岸長期觀測、資料蒐集、即時監控及變更觀測模式。本文研究區域包含西子灣人工岬灣和人工養灘等部分海岸。將所得之海岸影像,利用商業軟體進行全景圖(Panoramas)拼嵌,以及運用座標轉換、邊緣偵測等影像處理方法,獲得西子灣海岸淤積增生、漂沙現象及波浪淺化…等相關特性分析。由此較低成本的海岸影像觀測系統分析方式,來分析西子灣海岸影像,經由長期架站可獲得良好的海岸影像追蹤結果以及灘線長時間的變化情形。

    The purpose of this study is to develop an image analysis system for coastal observation based on the pan/tilt camera. The pan/tilt camera instead of a number of cameras is used to capture multi-directional images for coastal observation, data collection, real-time monitoring and observation mode alteration. In this study, the field site includes the artificial headland and artificial beach nourishment of Shi-Hzuwan Bay. First, the coastal images obtained by pan/tilt camera are mosaicked into a coastal panorama by commercial software. Then the coastal characteristics of Shi-Hzuwan Bay (e.g., sand siltation, drift, and wave shoaling) are obtained by image processing (e.g., coordinate transformation and edge detection).. In this thesis, the coastal images of Shi-Hzuwan Bay are analyzed based on this low-cost coastal image observation system in which the behavior of the beach line can be traced in a long time.
