One of the key research issues in reverse engineering is about the geometric modeling restruction of parts with complex surfaces.In order to solve the problem that how to extract the boundary from point clouds,the boundary extraction method in reverse engineering based on slicing data of spiral scanning parts is investigated.The boundary extraction process consists of two major steps;at first,doing layer contour feature point extraction and fitting cross section outlines using adjacent layer feature points after slicing the point clouds.Then,the trajectory can be fitted though the adjacent layer boundary points.This method is proven to be operability and practicability though one typical spiral scanning part.
