Oversized model lightweight method based on ship feature extraction and electronic equipment

Abstract

The invention relates to the technical field of ship digital virtual aided design, in particular to an oversized model lightweight method based on ship feature extraction and electronic equipment. The method comprises the following steps: firstly, defining a model display data structure adaptive to the oversized data volume of the ship by adopting a multi-document lightweight display technology; then, aiming at model characteristics of a ship structure, a pipeline, equipment and the like in the ship model, constructing a lightweight algorithm library adaptive to each professional model; and finally, defining a plurality of sets of models with different precision levels by adopting a multi-level display method to obtain hierarchical expressions of the models and realize differential display of the models with different precision levels. The invention can adapt to the data size characteristics of the ship super-large model, the problem that a current three-dimensional software platform is generally lack of big data model display support is solved, the ship three-dimensional scene can be optimally displayed, the hardware load is effectively reduced, and real-time roaming of the ship super-large model scene is achieved.

Description

technical field [0001] The invention relates to the technical field of ship digital virtual aided design, in particular to a super-large model lightweight method and electronic equipment based on ship feature extraction. Background technique [0002] Digital prototype technology can enable designers, craftsmen and even installation and maintenance personnel to grasp the comprehensive performance and possible problems of the product before the physical prototype is manufactured, so that digital prototype technology can be integrated into the entire process of the product life cycle, It can effectively reduce design errors and modification frequency. [0003] Using concurrent design, virtual design, and computer-aided design and manufacturing of ships based on virtual reality technology is the direction of future digital shipbuilding development. For ship products, the 3D digital prototype model of the whole ship is huge, and the number of original triangular faces is expected...

AI Technical Summary

Problems solved by technology

[0004] The existing digital sample ship aided design technology has the problem of large amount of model data, which requires high hardware such as graphics card and CPU, and it is difficult to realize the real-time roaming effect of the whole ship data; when the data amount of the model reaches a certain level, in the computer The virtual maintenance process of the operation model will have poor real-time performance, which will affect the virtual maintenance process simulation and interference inspection of the model; in the process of ship product design, different disciplines often need to carry out collaborative design, and different disciplines need to coordinate technically on the large model. When the amount of model data is large, it will affect the coordinated display of the model and the smooth progress of collaborative design
