Abstract

The invention provides a PDS three-dimensional model analysis and reconstruction method. The method involves a model analysis module and a model reconstruction module. The model analysis module comprises a DGN file element acquisition module (S11), an information extraction module (S12) and an information writing module (S13). The model reconstruction module comprises an assembly file creation module (S21), an information analysis module (S22) and a model reconstruction module (S23). According to the PDS three-dimensional model analysis and reconstruction method provided by the invention, geometric information and attribute information of a DGN three-dimensional model can be analyzed and the DGN three-dimensional model is reconstructed into an accurate model in other format, so that a user can perform accurate virtual simulation verification and display on a PDS model by using virtual reality software.

Description

technical field

[0001] The invention relates to the fields of three-dimensional design and virtual reality, in particular to a PDS three-dimensional model analysis and reconstruction method. Background technique

[0002] In the field of digital design, when the 3D model constructed by 3D design software is used for virtual simulation verification, it is necessary to convert the model format, and there is often a problem of model information loss in the process of model conversion and transmission.

[0003] The virtual verification or display functions of the 3D design software PDS (widely used in petroleum, chemical, and energy fields) or Microstation are not powerful, and other software such as DELMIA is required for simulation verification. At this time, the DGN model (PDS model is in DGN format ) into a format compatible with virtual simulation software. When using the model format conversion plug-in that comes with Microstation software for conversion, there are problem...
