QUALITY MANAGING METHOD FOR CONSTRUCTION MATERIAL USING REVERSE MODELING AND RECONSTRUCTION DETERMING METHOD USING REVERSE MODELING

摘要

A construction material quality management method using reverse modeling according to the present invention comprises the steps of scanning construction materials using a 3D laser scanner (500); enabling a computer processor device to generate a 3D model using scan data obtained through the 3D laser scanner (501); and enabling the computer processor device to compare by analyzing the 3D model with the 3D CAD model for construction materials. A method for determining the quality comprises the steps of extracting a 3D CAD model for the construction materials from a CAD database (502); merging the 3D model and the 3D CAD model (503); calculating a deviation between the 3D model and the 3D CAD model (504); and determining the quality of the construction materials according to whether the deviation exceeds a quality reference value (505).
