Pipeline joint BIM refined modeling method and device, electronic equipment and storage medium

Abstract

The invention discloses a pipeline joint BIM refined modeling method and device. The method comprises the steps of obtaining two-dimensional vector pipeline and two-dimensional vector pipe point data corresponding to a target multi-way joint; cutting a two-dimensional vector pipeline corresponding to the target multi-way joint, and respectively calculating position coordinates of a joint pipe section and a pipe cap; according to the distribution of the target multi-way joint, decomposing the target multi-way joint into a main pipe section, a branch pipe section and a pipe cap, and performing main pipe section modeling, branch pipe section modeling and pipe cap modeling respectively; performing mutual cutting calculation on the three-dimensional main pipe model and the three-dimensional branch pipe model based on entity geometric Boolean operation; and fusing the cut three-dimensional main pipe model, the three-dimensional branch pipe model and the three-dimensional pipe cap model, constructing a three-dimensional topological joint geometric grid, and hooking semantic information of each component to obtain a three-dimensional joint BIM model. According to the method, interpolation sampling is carried out according to real pipeline data, the three-dimensional joint BIM model keeping topology correctness is automatically constructed, joint outlet pipe sections are fused into a whole, and refined modeling is achieved.

Description

technical field [0001] The invention belongs to the field of computer modeling, and in particular relates to a method and device for BIM fine modeling of pipe joints, electronic equipment and storage medium. Background technique [0002] With the rapid development of the national economy and the continuous progress of the society, the construction of the city is also undergoing a new transformation. Urban construction is not only extending upwards, but also developing underground. Among them, the underground pipe network is an important basic information for urban planning, construction and management, and it is also a particularly important part of the management of urban infrastructure construction. The underground pipe network facility is a basic part of modern urban infrastructure, and it is the material transportation and discharge channel for the daily life of urban residents. The planning, laying, management and maintenance of urban underground pipe network directly...
