摘要: This paper presents our experience regarding the creation of 3D semantic facility model out unorganized point clouds. Thus, a knowledge-based detection approach objects using OWL ontology language is presented. knowledge used to define SWRL rules. In addition, combination processing built-ins and topological Built-Ins in rules aims at combining geometrical analysis clouds specialist's knowledge. allows more flexible intelligent annotation contained The created WiDOP prototype takes set as input, produces an indexed scene colored visualized within VRML output. context study railway materialized Deutsche Bahn such signals, technical cupboards, electric poles, etc. Therefore, resulting enriched populated domain ontology, that contains annotations clouds, feed GIS system.
