Reverse Engineering System for Free-Form Surface

Based on the studies of sampling planning and surface reconstruction , the reverse engineering system with non-contact measurement is developed. During digitizing, the adaptive sampling planning method based on the curvature of surface and the slope of tangent line of measured point is proposed. For surface reconstruction, the new adaptive extracting approach based on curvature of surface is developed so as to reconstruct the NURBS surface for the scattered data. The experiment shows that the system is reliable and efficient.
