Three-dimensional Surface Reconstruction Technology in Reverse Engineering

Surface reconstruction is an important part of CAD technology modeling in reverse engineering,surface reconstruction of scattered point cloud technology based on three-dimensional is a research focus.To the application of surface reconstruction of three-dimensional scan data points in the actual system,the article take this three-dimensional scattered point cloud as the research object,proposed a non-uniform rational B-spline surface construction method,which targets according to the known data point approximation surface.Through the system application,this method is an effective method of surface fitting reconstruction.
