Abstract

The invention discloses a constructional engineering quality control system based on combination of 3d laser sensing and BIM. The method comprises the steps of obtaining a BIM point cloud model and astructure point cloud model of a to-be-detected target, converting the structure point cloud model of the to-be-detected target into a BIM coordinate system where the BIM point cloud model is located,calculating the actual deviation between the BIM model under the BIM coordinate system and the structure point cloud model, and if the actual deviation is smaller than or equal to a preset controllable deviation in the BIM model, considering that the building quality is qualified; and if the deviation is greater than a preset controllable deviation in the BIM model, outputting a quality early warning. According to the invention, the constructional engineering quality of constructional engineering quality automatic detection can be efficiently realized in real time.

Description

technical field

[0001] The invention relates to a control system for construction engineering quality. Background technique

[0002] During the construction process, real-time quality control and early defect detection are important methods to ensure project progress and prevent overruns. Effective identification of early defects in the construction process is crucial for quality and cost control, because 6% to 12% of the construction volume is caused by rework caused by untimely defect detection. my country's current infrastructure is not perfect. In the process of realizing modernization, a large number of buildings will rise from the ground. It is of great practical significance to reduce the waste of resources and ensure the quality of construction during the construction process.

[0003] Current building quality inspection and control methods are time-consuming and inefficient. Generally, it is carried out in the following way: at a specific construction stage, for a...
