摘要
Aiming at the problems of low forming precision and low processing efficiency of the current slicing processing methods using spatial point cloud data for Reverse Engineering/Rapid Prototyping(RE/RP) integrated system, a series of efficient and effective algorithms were proposed. First, the Inverse Distance Square method (IDS) was adopted to determine the direction and thickness to make an adaptive slicing for the spatial point cloud data. Then, the extended extrapolation method was presented to obtain a vertical slicing contour curve. Moreover, the contour points in each layer were searched, sorted and reconstructed by applying Non-Uniform Rational B-spline (NURBS) interpolation method, and the reconstructed profile data points were homogenized and finished. Finally, several simulation results and the practical examples were given to demonstrate the novel methods which have a higher forming precision and processing speed for rapid fabrication.
