Propose Semantic Formalization for 3D Reconstruction of Architectural Objects

Archi3D project is a very successfully practice well proved by real engineering practices. In this paper, we propose to reconstruct semantics for the purpose of reconstruct 3D architecture in Archi3D fundamentally. The formalization approach starts from several hypotheses on semantics which include: there is a core mechanism of semantics which is not limited to conceptual expressions; and a complete expression of semantics necessaries the ¿implicita¿explicit¿ of human side knowledge, etc. The necessity and feasibility concerning applying the proposed method and technology to the practice of Archi3D is discussed systemically by way of semantics revelations on some cases related to natural language and logic expressions, etc.
