隱藏式室內廣角監控系統

本論文針對一般路面上轉角處所置放的廣角鏡進而改良為鍍膜廣角鏡，結合攝影機放置在室內公共場所達到一種隱藏式攝影機監控系統。一般傳統攝影機沒有偽裝，同時又有死角，導致暴徒可以選擇攝影死角施暴而事後無法蒐證的情形。鍍膜廣角鏡與一般傳統廣角鏡不同的是利用介電質薄膜材料讓安裝在內的攝影機達到隱密性且成像的效果。本論文為了增加拍攝視角，利用一般視訊攝影機視角62度兩顆製作具寬視野輔助縫合視訊，使拍攝角度比一般監控攝影機更為廣泛提高至112度。為提升縫合的視訊品質，進行分析實景縫合時所引發的問題。動態即時影像縫合技術基本概念以SIFT尺度不變特徵演算法為基礎來實現，並針對縫合後PSNR影像訊號雜訊比作裝設鍍膜廣角鏡後失真度測量比較。關鍵詞:真空鍍膜、影像縫合、SIFT、角度量測、Solidworks

This study aims at wide-angle lens around the corner of the roadside that is improved to coating wide-angle lens in combination with camera for an achievement of a hidden indoor wide-angle monitoring system in indoor public places. Traditional cameras have either no disguise or dead angle causing that the mob can choose photographic dead zone to use violence without evidences being able to collect afterwards. The difference between coating and normal traditional wide-angle lens is that the former uses dielectric coatings as material to reach confidentiality and imaging effect for camera installed inside. Two ordinary video cameras at 62° visual angle for the purpose of increasing shooting visual angle to comprehensively increase to 112° more than that of ordinary surveillance camera. For the promotion of stitched video quality, problems incurred from real scene stitch will be analyzed. The basic concept of using dynamic instant image stitching technology is to be realized on the basis of SIFT (Scale Invariant Feature Transform) algorithm, and distortion measurement between PSNR (Peak Signal-to-Noise Ratio) after being stitched and costing wide-angle lens after being installed is then compared. Keywords: Vacuum coating、Image stitching、SIFT、Measuring Angles、Solid works
