Problems solved by technology

[0004] Due to the inevitable errors in measurement and construction of super high-rise buildings, there are deviations between the actual constructed structure or components and the design. Once the deviation exceeds the allowable value or range of the code, it will not meet the design requirements on the one hand, and there will be safety hazards on the other hand.
For construction deviation, there is currently no effective and rapid inspection method, and construction measurement lacks a rapid verification method

Abstract

The invention provides a 3D scanning based digital testing system and method for construction deviation of a super high-rise building. Point cloud data of a super high-rise building structure is acquired by a 3D laser scanning subsystem for scanning, a construction deviation digital testing subsystem processes the point cloud data obtained through scanning, a 3D scanning model is obtained, design models are subjected to digital processing, deviation analysis is performed on the 3D scanning model and the digitalized design models, testing evaluation of construction progress, location and dimension deviation of the super high-rise building is obtained, and precise and rapid digital testing of the construction deviation of the super high-rise building can be realized.

Description

technical field [0001] The invention relates to a digital inspection system and method for super high-rise building construction deviation based on 3D scanning. Background technique [0002] The development of super high-rise buildings in large and medium-sized cities is conducive to solving the contradiction between the rapid increase in population and the extreme scarcity of soil resources. At present, my country's super high-rise buildings are in a period of prosperity and development. It is predicted that by 2020, more than 70% of the world's super high-rise buildings will be in China. Construction surveying plays an extremely important role in the construction of super high-rise buildings. Compared with conventional engineering, the measurement and control accuracy of super high-rise buildings is higher, and most of them exceed the technical indicators of existing specifications. At the same time, due to a series of effects such as temperature difference, sunshine, wi...
