distance to closest point of approach

A new algorithm to calculate the near distance spot of adjacent well by using cylinder helix method;

应用圆柱螺线法计算邻井最近距离点的新算法

First this method matched background using TSS and MCD and then it takes frame difference and wide off the background noise using grayscale morphology method.

该方法首先对相邻两帧运动图像利用三步搜索法和最多邻近点距离相关匹配准则进行背景匹配,然后对匹配后的图像进行帧间差分并对差分图像进行灰度形态学滤波以去除背景噪声点,最后利用阈值分割方法检测到运动目标的位置。
