Toward the Automatic Generation of a Semantic VRML Model from Unorganized 3D Point Clouds
Helmi Ben Hmida, Christophe Cruz, Christophe Nicolle +1
This paper presents our experience regarding the creation of 3D semantic facility model out of unorganized 3D point clouds. Thus, a knowledge-based detection approach of objects us…
From 9-IM Topological Operators to Qualitative Spatial Relations using 3D Selective Nef Complexes and Logic Rules for bodies
Helmi Ben Hmida, Christophe Cruz, Frank Boochs +1
This paper presents a method to compute automatically topological relations using SWRL rules. The calculation of these rules is based on the definition of a Selective Nef Complexes…
Knowledge Base Approach for 3D Objects Detection in Point Clouds Using 3D Processing and Specialists Knowledge
Helmi Ben Hmida, Christophe Cruz, Frank Boochs +1
This paper presents a knowledge-based detection of objects approach using the OWL ontology language, the Semantic Web Rule Language, and 3D processing built-ins aiming at combining…
Integration of knowledge to support automatic object reconstruction from images and 3D data
Frank Boochs, Andreas Marbs, Hung Truong +6
Object reconstruction is an important task in many fields of application as it allows to generate digital representations of our physical world used as base for analysis, planning,…
From 3D Point Clouds To Semantic Objects An Ontology-Based Detection Approach
Helmi Ben Hmida, Christophe Cruz, Frank Boochs +1
This paper presents a knowledge-based detection of objects approach using the OWL ontology language, the Semantic Web Rule Language, and 3D processing built-ins aiming at combining…
Ontology-based Recommender System of Economic Articles
David Werner, Christophe Cruz, Christophe Nicolle
Decision makers need economical information to drive their decisions. The Company Actualis SARL is specialized in the production and distribution of a press review about French reg…
From Quantitative Spatial Operator to Qualitative Spatial Relation Using Constructive Solid Geometry, Logic Rules and Optimized 9-IM Model, A Semantic Based Approach
Helmi Ben Hmida, Christophe Cruz, Frank Boochs +1
The Constructive Solid Geometry (CSG) is a data model providing a set of binary Boolean operators such as Union, Difference and Intersection. In this work, these operators are used…
