Abstract

The invention provides a 3D laser scanning based building prefabricated part quality detection system and method. Prefabricated part point cloud data is acquired through a master control and scanning of an auxiliary scanner, a 3D scanning mode obtained based on the prefabricated part point cloud data and a design model are compared and analyzed to achieve evaluation of prefabricated part size and surface quality, and the technical problem that size and surface quality detection of an existing industrial building prefabricated concrete part are completed manually and the efficiency is low can be solved.

Description

technical field [0001] The invention relates to a quality inspection system and method of building prefabricated components based on 3D laser scanning. Background technique [0002] my country's traditional construction production methods generally have problems such as high energy consumption of construction resources, low production efficiency, worrying project quality and safety, gradually rising labor costs, and serious resource shortages. Therefore, the construction industry urgently needs transformation and upgrading. Construction industrialization is one of the important ways to realize the transformation and upgrading of the construction industry, and it is also the key development direction of my country's construction industry during the "13th Five-Year Plan" period. [0003] Factory production of prefabricated concrete components is an important part of construction industrialization. In order to ensure the production quality of precast concrete components, the ...
