Based on the Point Cloud Data of Columnar Structures to Tilt Analysis
Based on the problem that tilt and convergence of some cylindrical structures in the building regularly need monitoring after the construction is completed. 3 D laser scan technology was applied and 3 D laser scanner was used to get the point-cloud data of a cylindrical structure which was deformed for external extrusion in the course of construction. The slope of the structure was calculated by the method of calculating the elliptical circle through more adjustment and proved that the method of using the 3 D laser scan technology to monitor the tilt and convergence of some cylindrical structures in the building is feasible and stable. 3 D laser scan technology can be used to calculate the slope of the cylindrical structure with minor error.
