摘要
本文给出的算法可以在间距较大的等高线之间形成新的等高线,该算法以任意直线与B样条曲线求交算法为基础。新等高线的形成建立在原有等高线和已知的离散点等客观信息基础之上,等高线加密效果好。
When the intervals of the existing contours are too big, The given arithmetic can make new contours between them. The base of the arithmetic is the method of getting the intersection point of a line and a B-spline curve. creation of the new contours are based on objective information such as existed contours and knowed scatter points. The arithmetic shorten the contours＇ interval, and the result is preferable.
