Application of modeling reverse engineering technology based on laser scanning in construction supervision

Abstract

The invention discloses application of a modeling reverse engineering technology based on laser scanning in construction supervision. The technology comprises the steps that a supervision station is built, scanning parameters are set, the supervision station is spliced, point cloud data is processed, the earthwork volume is calculated, the quality is controlled, and concealed works and completiondata of a project are subjected to supervision operation such as three-dimensional digitizing archiving by using digital scanning modeling reverse engineering. According to the application, traditional construction supervision means are improved, three-dimensional laser scanning and reverse modeling are applied to the construction supervision process, a supervision engineer can conduct three-dimensional scanning and reverse BIM modeling on building entities, models of reverse BIM modeling are compared with models of design BIM modeling, data analysis is conducted, problems or deviations in theconstruction process are discovered, modification is conducted in time, supervision analysis is more accurate, and the management quality and the project management efficiency are improved.

Description

technical field [0001] The invention relates to the field of laser scanning, and specifically refers to the application of a reverse engineering technology based on laser scanning modeling in construction supervision. Background technique [0002] Construction supervision means that the supervision unit is entrusted by the owner to control the construction progress, quality, investment, safety, etc. of the project on behalf of the owner within the scope of the owner's authorization, manage the project contract and information, and coordinate a series of supervision on the relationship between all parties involved in the construction Management activities, the traditional construction supervision is that the relevant supervisors apply measurement tools according to the relevant quality acceptance specifications, and obtain data that can truly reflect the quality of the building through on-site testing and measurement, and compare the measured real data with the design data to ...

[0002] Construction supervision means that the supervision unit is entrusted by the owner to control the construction progress, quality, investment, safety, etc. of the project on behalf of the owner within the scope of the owner's authorization, manage the project contract and information, and coordinate a series of supervision on the relationship between all parties involved in the construction Management activities, the traditional construction supervision is that the relevant supervisors apply measurement tools according to the relevant quality acceptance specifications, and obtain data that can truly reflect the quality of the building through on-site testing and measurement, and compare the measured real data with the design data to conduct manual inspections. Evaluation, this method requires a lot of manpower and time to complete, and the real data measured cannot be guaranteed to be accurate, and data analysis cannot be performed macroscopically, which may cause some problems in the evaluation process
