Automatic Detection and Classi cation of Objects in Point Clouds using multi-stage Semantics

Abstract: Due to the increasing availability of large unstructured point clouds from lasers canning and photogrammetry, there is a growing demand for automatic evaluation methods. Given the complexity of the underlying problems, several new methods resort to using semantic knowledge in particular for object detection and qualification support. In this paper, we present a novel approach which makes use of advanced algorithms, and benefits from intelligent knowledge management strategies for the processing of 3D point clo… Show more

“…For instance, ontologies describing railway facilities are used together with 3D modeling algorithms for processing point clouds to guide 3D object detection and labeling [16]. In [19], authors employ an ontology with a set of semantic rules to select algorithms and related parameters for detecting specific types of objects in a point cloud. In other fields, ontologies are used for better representation, sharing and reuse of spatial data.…”
