碩士 === 國立政治大學 === 地政學系 === 106 === Due to the significant improvement of wearable devices, virtual reality (VR) and augmented reality (AR) applications have been developed rapidly. To support various VR and AR applications, three-dimensional models are essential tools. Moreover, a flexible, efficient and real-time processing to generate 3D models is highly required. To achieve this, smart phone nowadays equipping with GNSS receiver, MEMS-based IMU, excellent computational capabilities and high resolution camera becomes a possible solution for purpose of low-cost and accessible mobile mapping system (MMS). In this study we developed a smartphone application aiming for interior space model reconstruction. With the technique of monocular simultaneous localization and mapping (Mono SLAM) and data collected through IMU in smartphone, users are able to reconstruct, localize and visualize the 3D model of interior space. In additional, by using the system we designed in the application, users can interactively guide the reconstruction process to resolve the structural ambiguities and errors during the acquisition with MonoSLAM. The resultant 3D model can be displayed in near real-time.
