碩士 === 國立臺灣科技大學 === 建築系 === 102 === The research uses 3D laser scanner to record the 3D (Three-Dimensional) urban data and build based on former 3D scans of vertical and horizontal streets, this project will create the contents of “Digital City” gradually by scanning famous Taipei business districts near the streets as an extension from points, lines, to whole urban areas. As-built urbanscape database can be shared cross government departments as a way to integrating related urban information. 3D scans of building facades, which are part of an integrated environmental database, are feasible for deformation measurement. As-built data also present the most updated spatial information which can be edited cross disciplines. Finally, use mini laser scanner to integrate points by different software . Expression with simpler and recording variety of distinctive and characteristics street pedlars by the National Taiwan Normal University circle and the East District circle. 1.Taipei National Taiwan Normal University circle: ?郼he record and illustration of “Alley Commercial Activities” ?郼he interface between the circle and the National Taiwan Normal University Campus ?郼he conflicts between the residential area and he commercial activities ?郼he variation of alley facades 2.Taipei East District circle: ?郼he presence of large department stores ?逭ulti-level connections between business blocks ?郼he construction and as-built scenes near main transportation (MRT) neighborhood facilities in east Taipei ?郿cans of street facades The purpose of this study is to build-up precise digital urbanscape, based on as-built architectural, landscape, and urban forms using a 3D long range scanner. The urbanscape includes 1) static scenes contributed by building facades, plants, open spaces; and 2) dynamic scenes contributed by the circulations of human, vehicles, and objects. The contents of urbanscape will be retrieved by 3D long-range laser scanners and be analyzed afterward. The result is an information management system up to 4 mm precision level of geometries. The main in Taipei East District circle is ground scanning, and the assist is height scanning. Taipei National Taiwan Normal University circle is reverse. The combine of this research is used to different ways to do it. In the last , the scan points data could analysis of ancient maps, cadastral maps, diagrams and analysis variety of data.
