Innovative Design on Photography Platform for the Digitized Data of Original Cadastral Maps

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 peoples 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 kept 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 data.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.
