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

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
