摘　　要：基于位置的社交网络受限于二维的多媒体内容形式,并且这些社交内容与位置的联系仍不够紧密。为优化基于位置的社交网络,提出了一套将增强现实(augmented reality,AR)技术和地理围栏技术应用于社交网络的系统设计方案。在特定区域内将载有社交媒体的虚拟模型叠加到用户移动终端捕捉到的场景中,呈现逼真的增强现实效果。基于ARKit和CoreLocation框架,在iOS平台上完成了系统。该系统实现了移动增强现实环境下用户之间的信息交流与互动,增强了用户社交场景感知。Location-based social networks are limited by 2D social media content forms,and the connection between the social content and location is still not close enough. In order to optimize location-based social networks,we propose a system design scheme that applies augmented reality(AR)technology and geo-fencing technology to social networks. By overlapping the realistic scene captured from the users’ mobile terminal in a specific area with the virtual model containing social media,the realistic augmented reality effect is presented. The system is completed on iOS platform by the ARKit and CoreLocation frameworks. The information exchange and interaction between users in a mobile augmented reality environment are realized by the system,which enhances users’ perception of the social scene.
