    標題: 數位化紙圖保存攝影平台之創新設計
    Innovative Design on Photography Platform for the Digitized Data of Original Cadastral Maps
    作者: 黃家昶
    貢獻者: 應用空間資訊系
    關鍵字: Before the digital measurement technology has been applied, various maps measurement results were use graphical method. Among them, the number of cadastral maps and topographic maps is mostly. Cadastral maps related to people's rights, topographic map is used by engineering design. Both must be kept as the basis for data traceability. At present, most of these maps are digitally saved by scanning. However, there are different sizes of maps that need different sizes scanners. Image distortion may occur during scanning, causing misjudgment of subsequent map datas. In recent years, processing paper data into true orthophoto through multi-view image processing technology, the result of obtaining consistency with paper datas and maps has been verified and feasible. However, the verification method is too simple. It is quite inconvenient for the map datas that need to be processed in large quantities. This study will design a simple and convenient photography platform, through Smooth moving slide rail system and height-adjustable shooting base, can quickly capture fixed-position results for image processing. Expand the number of experiments and the type of maps in the verification process. Research results show that this new photography platform can effectively speed up processing and expand the multi-size maps. There is considerable help in the subsequent preservation of cadastral data.

    摘要: 在數值測量技術尚未應用之前,各種圖籍測量成果皆為圖解法測量的紙圖,其中以地籍圖和地形圖數量居多,地籍圖關係民眾權益,地形圖是工程設計之用,二者皆須保存作為資料溯源之依據。目前雖多利用掃描方式將這些紙圖進行數位化保存,然會面臨需有不同尺寸的掃描儀因應大小不一的紙圖,和掃描過程中產生的影像扭曲失真,造成後續圖籍資料的誤判問題。
