面向iOS的移动端全景地图构建方法

Research on Panorama Image Map Service on iOS Mobile Device

随着移动互联网和街景地图的发展,基于360°全景影像的街景地图服务将成为移动互联网时代位置服务的主流趋势。该文提出了一种面向iOS移动端的全景地图应用构建方法。首先,提出基于球面模型的移动端全景场景构建、纹理贴图和渲染优化的技术方法;其次,针对移动终端应用模式,设计了面向移动终端的全景地图数据服务的技术框架;最后,采用移动端全景地图模型和数据服务框架,实现了iOS下移动端全景地图的开发。实验结果表明移动端全景浏览流畅,可以广泛应用在增强现实位置服务,具有很好的应用前景。

With the development of mobile Internet and Street View technology,it′s highly possible that Street View Service based on 360°panorama image becomes the main stream of Location Based Service.In this paper,a construction method of iOSoriented panorama image map service is presented.Firstly,panorama image scene construction,texturing mapping and rendering optimization based on spherical panorama model in mobile device is presented.Secondly,a data service technology framework of panorama image map is designed.Finally,an iOS based panorama image map application prototype is implemented using the spherical panorama model and the aforementioned data service.The experiment result shows that the panorama image can be viewed fluently which can guarantee a promising prospect in enhanced reality LBS（Location Based Service）.
