The interest in generating 3D models has been motivated by a wide range of applications such as urban planning and GIS. In recent years, the demand for 3D photorealistic building models has dramatically increased. These needs arise particularly from 3D GPS navigation systems and on-line services such as Nokia, Google, and Apple maps. According to Parks Associates (2010), the number of Smartphone users worldwide is predicted to exceed 1 billion by 2014. The mobile location based services (MLBS) including advertising and marketing is to generate multi-billion revenues, as a recent report from Juniper Research showing that the market of MLBS is expected to reach more than $12.7 billion by 2014. Maps are the backbone of the location based services, where the three dimensional maps are one of the most important features in the next generation maps. To date, no efficient solutions are able to fully automate the creation of photorealistic building models with ground-level details from LiDAR (Light Detection And Ranging). Automatic methods could significantly increase productivity, reduce costs, and be of enormous interest to location based service providers.

对生成3D模型的兴趣受到诸如城市规划和GIS等广泛应用的激发。近年来，对3D真实感建筑模型的需求急剧增加。这些需求特别来自3D GPS导航系统和在线服务，如诺基亚，谷歌和苹果地图。根据Parks Associates（2010）的数据，到2014年，全球智能手机用户数量预计将超过10亿。包括广告和营销在内的移动的基于位置的服务（MLBS）将产生数十亿美元的收入，Juniper Research最近的一份报告显示，MLBS市场预计到2014年将达到127亿美元以上。地图是基于位置的服务的支柱，其中三维地图是下一代地图中最重要的特征之一。到目前为止，还没有有效的解决方案能够完全自动化地创建具有LiDAR（光探测和测距）地面细节的逼真建筑模型。自动化方法可以显著提高生产率，降低成本，并对基于位置的服务提供商产生巨大的兴趣。
