3D factory generation method and system based on RVM data, medium and equipment

Abstract

The invention relates to a 3D factory generation method based on RVM data. The method comprises a data reading step, a hierarchical structure analysis step, a three-dimensional model reuse judgment step, a 3D factory construction step and a grid data compression optimization step. Traversing all the three-dimensional models, and reading an RVM file in a binary format and an ATT file in a Json format; analyzing a hierarchical structure of the RVM and objects of a basic body and a non-basic body of leaf nodes of the hierarchical structure, and obtaining attribute information of each three-dimensional model based on the read ATT file; performing multiplexing judgment on the basic body and the non-basic body according to the geometric type, the size or the type identifier; performing triangular patch processing based on a reuse result of the three-dimensional model, and performing compression optimization on grid data; and reconstructing the RVM hierarchical structure according to the scene construction and business requirements of the 3D factory to be generated. The invention also relates to a 3D factory generation system, a medium and equipment based on RVM data.

Description

technical field [0001] The present invention relates to the technical field of 3D modeling, and in particular, to a method, system, medium and device for generating a 3D factory based on RVM data. Background technique [0002] At present, PDMS (PlantDesignManagementsystem) is the three-dimensional layout design management system of the factory, which is known as the preferred design software system for large and complex factory design projects, and is widely used in petroleum, chemical, electric power, gas, steel structure and other fields. It can create full-scale 3D models with geometric information and attribute information, has a powerful component library, supports multi-discipline (architectural, structural, electrical, equipment, HVAC, instrumentation, etc.) collaborative design, and can be exported as open exchange files, Model data files (.rvm) and attribute auxiliary files (.att). [0003] The RVM data contains complete geometric information and material informati...

Problems solved by technology

In addition, in the process of parsing RVM and ATT data, the original ecological tree structure has not been effectively sorted out and reorganized, and the multi-level structure has not been fully utilized, which affects the model building of the 3D factory and the development of related businesses in the later stage

[0005] In order to solve the problems existing in the existing technology, it is urgent to develop a 3D factory generation method based on RVM data, which can simultaneously solve the problems of 3D large model loading and 3D factory structure reconstruction
