摘　　要：城市建筑屋顶立面是待开发的珍贵资源。针对屋顶立面进行装饰设计,可极大提高城市景观水平。特别是结合屋顶绿化等生态屋顶装饰技术,对城市绿色低碳发展亦有较大作用。本文提出了一种利用无人机倾斜摄影进行城市屋顶立面装饰潜力调查的方法。首先利用四轴无人机对城市进行倾斜摄影信息采集,然后通过空间三角测量算法重建城市三维实景模型,再使用GIS技术提取城市屋顶立面,并进行相关绿化装饰潜力分析。该方法运用数字化手段,极大地提高了城市屋顶立面的调查分析效率,对城市景观水平提高及绿色低碳发展有一定意义。The roof facade of urban buildings is a precious resource to be developed. The decoration design of roof facade can greatly improve the level of urban landscape. Especially in combination with eco-roof decoration technologies such as roof greening, it also plays a great role in the green and low-carbon development of cities. This paper presents a method to investigate the decoration potential of urban roof facades by using UAV oblique photography. Firstly, the four axis UAV is used to collect the oblique photography information of the city, and the three-dimensional real scene model of the city is reconstructed through the spatial triangulation algorithm. Then, the GIS technology is used to extract the urban roof elevation, and the relevant greening decoration potential is analyzed. This digital method can greatly improve the investigation and analysis efficiency of urban roof facades, which is of great significance for the improvement of urban landscape level and green low-carbon development.
