NEW METHOD FOR FREE-FORM SURFACE FITTING IN PRECISION METROLOGY

• Abstract:

  To assess if a given manufactured artifact conform to a template CAD model, the artifact is measured by a coordinate measuring system to obtain a point cloud. The point cloud is compared to the CAD model by fitting the point cloud to the CAD model. One of approaches is based on a method required to determine footpoint parameters.
  The footpoints are the projection of the points in the point cloud onto the CAD surface. In this paper we introduce a new efficient method for estimating footpoint parameters.
