A System and Method for Orientating Scan Cloud Data Relative to Base Reference Data

摘要

Abstract A system for orientating scan cloud data of a surface relative to base reference data system for aligning scan cloud with data with a base reference data for measuring he displacement of a surface relative to a base reference including a scanning means to generate point cloud data in respect of a measure of the spatial orientation of a distal surface relative to a reference point to define a three-dimensional image of said surface including an input source generator adapted to provide said scan cloud data and storage means to store base reference data in respect of the spatial orientation of a base reference relative to said surface and a tilt-correction means for orientating said point cloud data relative to the base reference data; and a data editing means to filter spurious point data from the accumulated point cloud data and a processing means to process said point cloud data and said base Reference data to determine the relative displacement of said surface with respect to said base reference, The system also provides Ofor the measurement of the volume of objects that are nonfixably connected to a surface and to measure the size of apertures in a surface. Finally, the invention provides a system for identifying features in scan cloud data of a surface including an input source Generator adapted to provide said scan cloud data and a partitioning means to partition said point cloud data into discrete segments Corresponding to different geometrically described sections of said surface.
