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.

城市规划和 GIS 等广泛的应用激发了人们对生成 3D 模型的兴趣。近年来，对 3D 逼真建筑模型的需求急剧增加。这些需求尤其来自 3D GPS 导航系统和在线服务，例如诺基亚、谷歌和苹果地图。根据 Parks Associates (2010) 的预测，到 2014 年，全球智能手机用户数量预计将超过 10 亿。Juniper Research 最近的一份报告显示，包括广告和营销在内的移动定位服务 (MLBS) 将产生数十亿美元的收入显示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，其中三维地图是最重要的特征之一在下一代地图中。迄今为止，还没有有效的解决方案能够完全自动创建具有 LiDAR（光检测和测距）地面细节的逼真建筑模型。自动方法可以显着提高生产力，降低成本，并且引起基于位置的服务提供商的极大兴趣。
