Building reconstructing system and method based on three-dimensional laser scanning and three-dimensional printing

Abstract

The invention provides a building reconstructing system and method based on three-dimensional laser scanning and three-dimensional printing. By means of a three-dimensional laser scanning measuring subsystem, a data processing and three-dimensional modeling subsystem, a three-dimensional model analysis and amendment subsystem and an entity building three-dimensional printing subsystem, the technical problems that by means of a traditional monitoring method, only single-point data can be obtained, reliability is low, and the requirements of building reconstructing mapping for a large scale, quick and accurate measurement and the like cannot be met are solved. The problems that in a traditional single-point type monitoring method in building reconstructing mapping, the monitoring range is small, informatization is low, and construction efficiency and the automation degree of traditional building reconstructing are low are solved. The problem that a traditional printing device cannot move or extend in a horizontal plane range is solved. Building point cloud data can be obtained rapidly with large areas and high precision in a non-contact mode, and rapid, efficient and automatic construction of a building can be achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a building reconstruction system and method based on three-dimensional laser scanning and 3D printing. Background technique [0002] my country has successively issued a series of programmatic documents including "National High-tech Research and Development Plan (863 Plan)", "National Additive Manufacturing Industry Development Promotion Plan (2015-2016)" and "Made in China 2025", all of which will include 3D printing Technology as a national strategy for priority development. At present, the automation level of the construction industry is still lagging behind compared with other industries, and its development urgently needs transformation and upgrading. 3D printing architecture has the characteristics of high degree of automation, one-time molding, less construction consumables and process loss. In view of the current situation of extensive construction in the c...
