Abstract

The invention provides a prefabricated part point cloud automatic mold closing method based on particle swarm optimization variable domain search matching points. The prefabricated part point cloud automatic mold closing method comprises the steps: inputting prefabricated part point cloud, retrieving a corresponding BIM model, discretely extracting contour point cloud data by the BIM model, re-sampling, roughly matching and judging, grading important parts of the BIM model, searching and pairing matching points, optimizing a spatial position and the like. The invention provides a technical method for automatically carrying out mold closing by the prefabricated part point cloud and the BIM design model, effectively solving the problem that a large amount of human intervention is needed forassembling the prefabricated part point cloud and the BIM design model during quality detection, and providing method support for later size data estimation.

Description

technical field

[0001] The invention relates to the field of building safety management, in particular to a prefabricated component point cloud automatic mold-closing method based on particle swarm algorithm variable domain search pairing points. Background technique

[0002] In the prefabricated construction industry, in order to ensure the successful installation of prefabricated components at the construction site, strict quality inspections are required before transportation. The quality inspection method currently used is the traditional manual measurement method. Manual measurement of prefabricated components has obvious disadvantages, such as: large personnel consumption, high time and money costs during the detection process, and once the workload is too large, it is easy to cause human detection errors. Therefore, when faced with a large number of prefabricated components and complex component forms, the use of three-dimensional laser scanning measurement technolog...
