Three-dimensional scene cooperative construction system based on three-layer body, and realization method thereof

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.
