增强现实技术在城市功能性建设中的应用研究

Application of Augmented Reality Technology in Urban Functional Construction

随着新媒体技术的推广普及,"虚拟化"开始从单体向区域融合发展,人们对超现实生活的追求应运而生。目前,虚拟信息几乎无一例外地在屏幕空间完成,缺乏与三维场景的有效融合,其主要原因在于面向城市大场景增强现实模型的缺失。针对城市增强现实应用中高融合度信息在线展示的需求,文章提出一种面向大规模城市场景的增强现实模型。该模型通过统一空间位置融合了由真实世界数据构成的实景模型、由场景模型及中介面片构成的虚景模型、由虚拟提示信息及其组织方式构成的虚拟信息模型。

With the popularization of new media technology, ＂virtualization＂ begins to develop from monomer to regional integration. People＇s pursuit of surrealistic life arises at the historic moment. At present, most of virtual information completes in screen space, and lacks effective integration with 3 D scene. The main reason is the lack of augmented reality models for large urban scenes. Aiming at the need for online display of high integration information in urban augmented reality applications, this paper proposes an augmented reality model for large-scale urban scenes. The model integrates the real scene model composed of the real world data, the virtual scene model composed of the scene model and the intermediate patch, and the virtual information model composed of the virtual prompt information and its organization mode through the unified spatial location.
