Abstract

The invention discloses a method and system for realizing data compression of a transformer substation three-dimensional model. The method comprises: traversing sub component model data in a transformer substation three-dimensional equipment model; carrying out grouping matching on sub components in the transformer substation equipment model by using a model feature matching method and obtaining a reference model from each kind of sub component model set; on the basis of the reference model, calculating spatial transformation parameters of the involved kind of all component models relative to the reference model; according to the calculated spatial transformation parameters, carrying out indexing and recoding on the transformer substation equipment model to complete data compression of the three-dimensional scene of the transformer substation. According to the embodiment of the invention, united coding is carried out based on the reference models, thereby substantially reducing the data flow of the three-dimensional scene of the transformer substation and realizing data compression of the three-dimensional scene of the transformer substation. Therefore, the transmission efficiency of the three-dimensional scene of the transformer substation is improved.

Description

technical field [0001] The invention relates to the technical field of power system simulation, in particular to a method and system for realizing data compression on a three-dimensional model of a substation. Background technique [0002] With the development of information technology, virtual reality technology and other digital means are currently used to realize the digitalization of substation scenes. A network-based substation simulation system is constructed in the substation simulation training environment to realize real-time monitoring, information sharing and simulation training of substations. In order to achieve a high-quality visual experience, the amount of data in the 3D scene of the substation is often large. However, during network transmission, the large amount of data will increase the network transmission time, causing delays in real-time browsing of the 3D scene of the substation. How to reduce the amount of data in the 3D scene of the substation while ...
