Campared wih the old methods, it has two advantage: 1 It can be applied expediently. 2 In this method, where the dispersive curve skips can be seen distinctly in the range of the whole survey line and the position of air-raid shelter can be easily estimated. A new exploration example was offered by this method.

在探测防空洞时，该方法比其它的方法具有明显优点，即施工方便，并能在一条测线的范围内准确清楚地看到频散曲线的跳跃，从而判断出防空洞的位置。

Given a planar point set,the moving least squaremethod is adopted to denoise and resample it so that the resulting point set is with low noise and uniform sampling density.Then the reliable signed distance field of the preprocessed point set is constructed by using the Level Set method.Finally,an algebraic B-spline function is adopted to fit the signed distance field by solving a linear equation system.

首先给定一个表示封闭曲线、可能带有噪音且分布不均匀的平面点云，采用移动最小平方(moving least square，简称MLS)方法对点云去噪、重采样，得到一个低噪音、分布均匀的"线状"点云，再通过Level Set方法建立该"线状"点云的离散几何距离场，最后用一个代数B-样条函数光顺拟合该离散距离场，代数函数的零点集即为重建曲线。
