本研究為台北師大與東區商圈三維數據的記錄，建立已有之都市垂直、水平交通幹道紀錄，由點、線擴展至面之都市區域，針對台北市交通軸線周邊商圈掃瞄逐步完成「數位都市」內容。
現況都市景觀數位資料庫建立之成果可作為跨部會整合用之共用數位都市景觀模型，3D 外觀之描述不僅可建立具體可量測變異之描述資料且跨領域較具公信力，並可視需求增刪。
最後再以小型掃瞄器以不同軟體把點雲數據結合在一起，試圖使點雲的資料以更簡單的方式去呈現，並且記錄下師大與東區商圈內部較有特色的小攤販，用各種面向去記錄這兩個商圈特色。
1.台北市師大商圈探討議題如下：
文教住宅社區「巷弄商圈」風貌之記錄與呈現。
商圈街道空間與師範大學校園介面掃瞄記錄。
居住與商業空間衝突之辨識。
沿街面之巷弄景觀改變記錄。
2.台北市東區商圈探討議題如下：
大型購物百貨風貌之記錄與呈現
多層次商圈空間3D掃瞄紀錄
臺北市東區重要轉運站週邊設施現狀或施工掃瞄記錄
重要幹道掃瞄
本研究運用長距離3D 掃瞄器建立精確的都市數位景觀，以現況資訊為擷取對象，將都市建物立面、植栽綠地、開放空間等靜態景觀及人、車、物流路徑動態景觀掃瞄記錄、分析、比對，建構一外觀描述模型精度可達4mm 之都市資訊系統。
其中東區商圈以地面點為主、制高點為輔；師大商圈則是相反本研究以不同結合方式去做結合並且將掃瞄到的點雲資料與古地圖、地籍圖、分析數據圖等各種圖面去做分析。
關鍵字:電腦模型建構、建築、都市設計、三維掃瞄、現況資料、商圈、夜市、攤販

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:
The record and illustration of “Alley Commercial Activities”
The interface between the circle and the National Taiwan Normal University Campus
The conflicts between the residential area and he commercial activities
The variation of alley facades
2.Taipei East District circle:
The presence of large department stores
Multi-level connections between business blocks
The construction and as-built scenes near main transportation (MRT) neighborhood facilities in east Taipei
Scans 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.
Keywords: 3D computer modeling, architecture design, urban design, 3D scan, as-built data, circle, night market, street pedlars
