Abstract: As the technology of UAV plays an increasingly important role in landscape planning and design, it has become possible to introduce technology of UAV into Landscape Architecture design and teaching. This article explained the concept, technological process, and advantages of UAV 3D reconstruction technology, application of the technology in landscape architecture design. This article also showed the way of combining technology of UAV with designing and teaching of Landscape Architecture based on UAV 3D reconstruction of current model, combining the landscape design, teaching and cutting-edge science with technology.
