摘　　要：将移动端增强现实(AR)技术引入海洋地貌可视化中,从海洋洋体和海底地貌两个方面探讨了海洋地貌AR可视化应用系统的设计思路和实施方案。首先将某一海域的海底地貌进行标准化处理,利用Blender建立海洋三维地貌模型;再基于Unity设计实现面向移动端的海洋地貌AR可视化交互系统,突破了目标识别、跟踪注册、坐标转换等关键技术,实现了放大、缩小、旋转、视角变换以及海洋洋体与海底地貌模型属性修改等人机交互功能,将真实海洋世界与虚拟海洋世界相结合,取得了较好的应用效果。In this paper,we introduced mobile augmented reality(AR)technology into the ocean geomorphology visualization,and discussed the design strategy and implementation plan of AR visualization application system for ocean geomorphology from water body and submarine geomorphology two aspects.First of all,we made a standard processing for the submarine geomorphology of one sea area,and utilized Blender to establish a 3 D ocean landform model.And then,we used Unity to design and realize the interaction system on mobile terminal for ocean geomorphology AR visualization.We solved some key technologies,such as target recognition,tracking registration and coordinate transformation,and achieved zoom,rotate,perspective transformation and the attribute modification of water body and the submarine geomorphology model.This system combines the real ocean with the virtual ocean,and has achieved good result.
