| Abstract | For indoor wireless location, it is useful to have 3D models to document and to validate the results of the locations derived from wireless sensing equipment. Visualization using a 3D model also allows the user to generate a realistic mental model while navigating their virtual surroundings. While it is possible to build a 3D framework model from CAD drawings, the results do not feature the exact locations and models of indoor equipment, such as tables, fire sprinklers, fluorescent lamps, and so on. A 3D Terrestrial Laser Scanner (3DTLS) is a tool that can be used to record indoor 3D coordinates of real objects efficiently and effectively. It has remarkable advantages including high data acquisition rate, high accuracy and excellent spatial data density (Yusuf A. 2007). The resulting dense “point-cloud” of data makes it easy to model any scanned object. In this study, we summarize our experiences in scanning and modeling. Using visual C++ and OpenGL, we developed a 3D visualization platform that enables browsing and navigation of 3D models and other applications. A case study using 3DTLS at the NTU Position & Wireless Technology Center (PWTC) is also presented in this paper. |
