场地整理土(石)方量三维坐标自动解算中的几个问题

Several Problems in Auto-algorithm of the 3-D Coordinate of Cubic Meters of Earth (Stone) of Construction Site Renovation

直接针对一定数量的的观测数据进行处理。得到一系列散点的三维坐标，继而对散点进行曲面拟合，求得方格网结点的三维坐标，并采用最小二乘原理求场地最佳设计平面，从而实现用方格网法计算土（石）方工程量的目的。

By directly dealing with a certain amount of observation data, people find the 3-D coordinate of a series of scattering points. Then by fitting the curved surface, they find the 3-D coordinate of the intersection points.The least square method is adopted to seek the best surface design of the construction site. Therefore, the aim can be reached to calculate the cubic meters of earth (stone)by means of the mesh method.
