Problems solved by technology

However, the ontology structure has too many layers and is too complex to provide efficient use of knowledge. Applying it to 3D scene construction can guarantee a certain degree of semantic consistency, but reduces the efficiency of 3D scene construction.

Embodiment Construction

[0019] like figure 2 As shown, in this embodiment, a three-layer ontology is used to construct a 3D scene, and the implementation structure of the collaborative construction of a 3D scene is based on a three-layer ontology model. Annotation in scene construction, detection and verification of semantic constraints in 3D scenes.

[0020] This embodiment includes the following steps:

[0021] 1) Build a domain-related three-tier model ontology: Modelers analyze the characteristics of models involved in related domains and build a general ontology; model managers analyze the categorical relationships of 3D models to construct domain ontology; domain experts analyze the spatial relationships of domains Construct scene ontology with application constraints.

[0022] The general ontology mentioned starts from the actual scene modeling process and extracts some conceptual features that users care about. Its formal representation method is WGO={Object, Feature, Environment, Behavio...

Abstract

Provided are a three-dimensional scene cooperative construction system based on a three-layer body, and a realization method thereof. A three-layer body includes a general body, a field body and a scene body, wherein the general body is specific to the appearance characteristic of a three-dimensional model, the field body represents professional field knowledge, and the scene body unifies semantic constraints in a modeling process. Three layers are dependent in application, meanwhile are separate in construction, and have great expansibility. The three-layer body can eliminate semantic ambiguity of a three-dimensional model, and improve three-dimensional model reusability, and is of great importance to distributed three-dimensional scene multi-person cooperative modeling.

Description

technical field [0001] The invention relates to a construction technology in the field of computer three-dimensional scenes, in particular to an ontology construction method in the field of three-dimensional scene modeling, including a general ontology, a domain ontology and a scene ontology for collaborative modeling of three-dimensional scenes. Applying this three-layer ontology to the collaborative construction of 3D scenes can effectively improve the construction efficiency, improve the accuracy of model matching and retrieval, and facilitate the collaborative management of 3D models. Background technique [0002] With the continuous development and maturity of 3D modeling technology, 3D modeling in various fields has become more and more complex and involves the application of high-level domain knowledge. As more and more fields involve the construction of 3D scenes, the traditional single-computer design mode is facing severe challenges. How to break through the tradit...
