Abstract

The invention discloses a model simplification method and device, electronic equipment and storage equipment, and relates to the field of buildings. The method comprises the following steps: acquiring at least one target geometric instance in a target model; performing geometric discretization processing on each target geometric instance to generate discrete grid data corresponding to each target geometric instance; and simplifying the discrete grid data, and updating the target model based on the simplified data so as to simplify the target model. The discrete grid data is simplified by adopting the method, and the target model is updated based on the simplified data, so that the simplification of the target model is realized. Therefore, the simplified target model is convenient to share and exchange. Moreover, the method can effectively recognize and remove the local detail features of the target model, only keeps the main contour of the target model, and effectively reduces the geometric complexity of the target model.

Description

technical field [0001] The invention relates to the field of architecture, in particular to a model simplification method, device, electronic device and storage device. Background technique [0002] Building Information Model (BIM), as the core technology of intelligent manufacturing in the construction industry, is constantly developing and is widely used in the construction field at home and abroad. The open source BIM data standard IFC (IndustryFoundation Classes) is used for data between various BIM platforms Exchange and various applications of the BIM life cycle. The key of BIM technology lies in the efficient data sharing and exchange of models between multiple platforms and fields. However, the huge model scale and complex geometric expression of BIM have brought challenges to the storage, transmission and application of various scenarios. How to simplify the geometric expression data of the IFC model has become an urgent problem to be solved. [0003] However, the...
