摘　　要：本文根据遗传算法,提出了一种B样条曲线逼近大量测量点的方法。为了使曲线具有良好的光顺性和曲线在端点处较好的控制性,本文采用端点插值的三次非均匀B样条算法逼近测量数据点。An method based on generic algorithm is presented to construct a B-spline curve approximating given data points. To construct a smooth curve and make curve with better controllability in first and last data points, the cubic non-uniform B-spilne curve with interpolation in first and last data points is used to approximate measuring data points.
