Method, system and storage medium for slice fusion of multi-source heterogeneous models

Abstract

The present invention provides a slice fusion method, system and storage medium of a multi-source heterogeneous model. The method includes: performing grid division or block processing on model data; according to the vertex density of any grid data or any block data, Determine the slicing method for any grid data or any block data. The slicing method includes vertex clustering slicing method and edge folding slicing method; perform slicing processing to obtain multiple first slicing data and BIM models of oblique photographic model data a plurality of second slice data of the data; merge the plurality of first slice data and the plurality of second slice data respectively, and output the first slice model data and the second slice model data; the first slice model data and the The second slice model data is fused. According to the vertex density contained in the grid data or block data, the present invention slices in different ways, without changing the original data model, and also reduces the data slice processing time.

Description

technical field [0001] The present invention relates to the field of data segmentation and fusion, and more specifically, to a method, system and storage medium for slice fusion of multi-source heterogeneous models. Background technique [0002] With the continuous development of oblique photographic models and BIM (Building Information Modeling, Building Information Modeling) technology, the amount of model data generated by them is increasing, which makes the speed of loading model data too slow. Therefore, in order to improve the loading efficiency, A common practice is to slice the model data to implement a loading mechanism at the LOD (Levels of Detail) level. [0003] At present, when slicing oblique photographic model and BIM model data, they are sliced ​​separately; in addition, for the same model data, for example, for all data of oblique photographic models or for all data of BIM models, the same The slicing method is used for slicing processing, which also increa...
