應用無人機傾斜攝影三維建模於遠距建成環境模擬之方法

<p>遠距山坡地區建成環境的環境模擬一直困擾規劃者，不僅僅是建成環境的調查測繪困難、3D建模與環境模擬不易，凸顯了規劃設計者的窘境。因此，本文嘗試利用遠距地區建成環境，以無人機傾斜攝影進行3D建模，以致於運用到環境模擬，研提一套簡便的方法論供規劃設計者參考。研究成果為：1.建置遠距地區建成環境模擬之方法論；2.透過陽明山中國文化大學為例實地案例分析，驗證遠距山區建構3D模型及物理環境模擬方法論的可行性。最後再討論此方法論的適用情況。</p> <p>&nbsp;</p><p>The environmental simulation of the built environment in the remote hillside area has always troubled planners. It is not only the difficulty of surveying and mapping the built environment, but also the difficulty of 3D modeling and environmental simulation, which highlights the dilemma of planners and designers. Therefore, this paper attempts to make use of the built environment in the remote area to carry out 3D modeling with UAV tilt photography, so as to apply it to the environment simulation, and to develop a set of simple methodology for planning designers’ reference. The research results are: 1. Establish the methodology of the built environment simulation in the remote area; 2. Through the field case analysis of Yangmingshan Chinese Culture University as an example, verify the feasibility of the construction of the 3D model and the physical environment simulation methodology in the remote mountain area. Finally, discuss the application of this methodology.</p> <p>&nbsp;</p>

Assessing the Effect of a Visual Navigational System on Route-Learning From an Ecological Perspective

Route-learning, considered from an ecological approach to perception, is posited to involve the detection of information over time that specifies a path from one location to another. The study examines whether the use of a visual navigational system (e.g., GPS) may impede route-learning by drawing attention away from transitions along a path that serve as information for way-finding. Virtual reality (VR) technology used in conjunction with an extensive, detailed environmental simulation was employed to explore this possibility. One group of participants drove a simulated car in VR along a designated path while relying on visual GPS guidance. It was expected that use of the GPS display would draw attention away from temporally continuous path information. A second group initially drove the same route without GPS guidance. Both groups drove the path a second time without navigational assistance. Overall, the percentage of correct actions taken at intersections (transitions) during the second trial were significantly lower for the first group who initially drove the route with visual GPS guidance as compared to those who initially traveled the route without it. The results are consistent with the kind of trade-off that is commonplace when tools are used to mediate and assist skilled action.
