An Approach of 3-Dimendional Modeling for Aircraft Recognition

A algorithm for adaptive data sampling of freeform surface based on chord approximate error is proposed to optimize the uneven spacing of data points acquisition.Furthermore,a modeling method applying this algorithm to construct complex surface objects is addressed.First,range data of control sections are extracted with measuring method in revere engineering.Then non-uniform cubic B-Spline curve is applied to fit the discrete data.Finally,using skinning method,the mode is made and object contour surface is reconstructed.
