Abstract

The invention belongs to the technical field of digital twinning, and particularly relates to a three-dimensional model reconstruction method and device based on point cloud, equipment and a storage medium. According to the method, fusion processing is carried out on acquired to-be-reconstructed point cloud data, the fused point cloud data is projected to obtain a projection point set, recessive feature recognition is carried out on the projection point set to obtain two-dimensional boundary features, and the two-dimensional boundary features of all projection surfaces are spliced to obtain three-dimensional boundary features of the fused point cloud data. The three-dimensional boundary features are matched with existing three-dimensional components in a model library, the matched existing three-dimensional components are determined as target components, the scale of the target components is adjusted until the scale of the three-dimensional boundary features is met, the adjusted target components are determined as the three-dimensional model of the to-be-reconstructed point cloud data, and reconstruction of the three-dimensional model is achieved. The above process does not need to accurately analyze the point cloud features, so that the analysis efficiency is improved, and the accuracy can be improved by adopting a model library matching mode.

Description

technical field [0001] The present application belongs to the technical field of digital twins, and in particular, relates to a point cloud-based three-dimensional model reconstruction method, device, equipment and storage medium. Background technique [0002] At present, in reverse engineering, 3D model reconstruction is the process of converting the 3D spatial information of the target object into a digital model. , BIM) reconstruction. The premise of object inverse reconstruction is to obtain the three-dimensional information data of the target object, and the three-dimensional information data can be obtained in various ways. However, the traditional data acquisition method is mainly realized by manual measurement method, which has a large workload, a low degree of automation, and it is difficult to obtain complete geometric data. 3D laser scanning is a new type of measurement technology, which has the characteristics of initiative, all-weather, non-contact, etc. It is...
