摘要
当机场噪声等值线生成后,需对其进行光滑处理,提出一种改进的三次B样条算法,该算法是在三次B样条曲线光滑的基础上改进此方法不经过型值点的缺点。通过反求型值点的控制顶点,由新产生的三次B样条曲线插值处理得到更多的等值点,从而既得到光滑等值线,又使光滑后的等值曲线经过每一个型值点。
Mter airport noise contour generated, the need for its smooth handling is necessary. This paper presents an improved cubic B-spline algorithm, which is based on the disadvantage of cubic B-spline curve that does not go through the data points. Through the Reverse data points control vertex, more equivalent points generated by the new cubic B-spline curve interpolation, which has been both smooth contour, and the contour after smooth passes each data ooints.
