提出了一种在城市景观的不规则间隔点云中检测城市结构的方法。该方法专门设计用于检测裸露地面的延伸结构（例如桥梁、坡道等）。该方法涉及对点云进行分割，然后进行分类。数据的分割和分类都是基于对数据结构的分析，其中点云表示为一组正交的剖面。还提出了用于结构检测问题的景观概念和逻辑模型。
A method for detecting urban structures in an irregularly spaced point-cloud of an urban landscape is proposed. The method is especially designed for detecting structures that are extensions to the bare-earth (e.g., bridges, ramps, etc.,). The method involves a segmentation of a point-cloud followed by a classification. Both the segmentation and classification of the data are based on the analysis of a data structure in which the point-cloud is represented as an orthogonal set of profiles. Also proposed is a conceptual and logical model of the landscape for the structure detection problem.
